ni kweli kutekelezwa kimwili.

7
00:00:18,720 --> 00:00:21,480
Na unaweza kukumbuka kwamba kuna
kweli rundo zima la nyaya

8
00:00:21,480 --> 00:00:23,690
kama vile waya
teknolojia ambayo kuunganisha

Ilikuwa kama biashara ilikuwa mvuke
wa habari kwamba duru Dunia,

Na hii ni kweli kitu
hasa karibu na moyo wangu.

muda mfupi baada ya kuhitimu, kwa kweli.

51
00:02:19,150 --> 00:02:22,280
Na kama nilikuwa exiting duka, hii
kijana mdogo ambaye alikuwa katika stroller

ilianza kugeuka halisi ya bluu.

kwa EMS tu kwa njia ya marafiki,

58
00:02:36,390 --> 00:02:37,597
kabisa froze.

59
00:02:37,597 --> 00:02:40,430

kama lifeguard 15 mwenye umri wa miaka ambaye

00:02:40,430 --> 00:02:43,460
mbio juu na kwa kweli alijua nini cha
kufanya instinctively na kutoa wito kwa msaada

61

na kwa kweli kujiondoa
mvulana nje ya stroller lake

62

Na kisha kwa vyuo vikuu wote
kutakuwa na CS50 haki

Na kwa kweli, mwisho
mwaka tulikuwa na programu $ 0.99

138

kwamba sisi kupakuliwa kutoka programu ya Windows
kuhifadhi ili kuteka juu ya screen.

139

>> Lakini kusema ukweli, ilikuwa na vitu vingi sana.

140
00:06:22,580 --> 00:06:24,996
Ni alituruhusu kuteka juu
screen, lakini kulikuwa na, kama,

141
00:06:24,996 --> 00:06:26,060
mengi ya icons hapa.

142
00:06:26,060 --> 00:06:27,580
Interface user ni pretty mbaya.

143
00:06:27,580 --> 00:06:28,845
Kama alitaka mabadiliko
mazingira fulani,

144
00:06:28,845 --> 00:06:30,420
kulikuwa na Clicks tu wengi damn.

145
00:06:30,420 --> 00:06:32,770
Na user interface--
au, vizuri zaidi,

146
00:06:32,770 --> 00:06:35,075

ilikuwa pretty suboptimal,

147
00:06:35,075 --> 00:06:36,950
hasa kutumia katika
hotuba mazingira.

148
00:06:36,950 --> 00:06:38,658
>> Na hivyo sisi kufikiwa nje
kwa rafiki ya yetu

149
00:06:38,658 --> 00:06:42,090
katika Microsoft, Bjorn, ambaye kweli
wamekuwa kufuatia pamoja na CS50 online.

150
00:06:42,090 --> 00:06:45,430
Na kama mradi wake wa mwisho,
kimsingi, alivyofanya neema sana

151
00:06:45,430 --> 00:06:48,630
kuchukua baadhi ya pembejeo kutoka kwetu kama na hasa
makala na user uzoefu

152
00:06:48,630 --> 00:06:49,350
tunataka.

161
00:07:14,420 --> 00:07:16,850
Na kama sisi kweli wanapendelea
turubai nyeupe, tunaweza kufanya hivyo.

162
00:07:16,850 --> 00:07:20,800
Hivyo anafanya hivyo sana kidogo
kwa kubuni na anafanya vizuri.

DAVID Malan: zote haki.

188
00:09:43,260 --> 00:09:45,900
Hivyo Stephen Colbert kipande cha
kwamba mimi ilionyesha muda tu iliyopita

189

ilikuwa kweli kwenye TV tu siku chache zilizopita.

190
00:09:47,947 --> 00:09:51,280
Na kwa kweli, kadhaa za wengine
tutaweza kuonyesha leo ni incredibly hivi karibuni.

191
00:09:51,280 --> 00:09:54,120
Na kwa kweli, mimi kinachosema
ukweli kwamba kiasi ya teknolojia

192
00:09:54,120 --> 00:09:56,900
na, kusema ukweli, mengi ya mawazo
tumekuwa kuzungumza juu katika CS50

193
00:09:56,900 --> 00:09:57,892
kweli ni omnipresent.

194
00:09:57,892 --> 00:09:59,850
Na moja ya malengo ya
Bila shaka ni hakika

195
00:09:59,850 --> 00:10:03,300
kuvipa wewe na ujuzi wa kiufundi ili
kwamba unaweza kweli kutatua matatizo

198
00:10:08,110 --> 00:10:11,420
Na, kwa kweli, ufadhili katika
vyombo vya habari na video online na makala

199
00:10:11,420 --> 00:10:15,100
siku hizi ni tu ya kutisha
kutokuelewana au ukosefu

200
00:10:15,100 --> 00:10:18,640
ya uelewa wa jinsi teknolojia
kazi, hasa miongoni mwa wanasiasa.

201
00:10:18,640 --> 00:10:22,091
>> Na hivyo kweli kweli, kidogo tu tutaweza
tuangalie mmoja wa wale maelezo,

202
00:10:22,091 --> 00:10:22,590
vilevile.

203
00:10:22,590 --> 00:10:24,660
Lakini literally tu mwisho
usiku alikuwa amekaa mimi

204
00:10:24,660 --> 00:10:27,600
katika Bertucci wa, ndani
franchise Italia mahali.

205
00:10:27,600 --> 00:10:28,960
Na mimi hopped juu yao Wi-Fi.

206
00:10:28,960 --> 00:10:32,220
Na mimi nilikuwa kuhakikishiwa sana
kuona kwamba ni salama.

207
00:10:32,220 --> 00:10:35,710
Najua kwamba kwa sababu anasema
hapa "Salama Internet Portal"

208
00:10:35,710 --> 00:10:36,710
wakati screen akapanda.

209
00:10:36,710 --> 00:10:38,918
Hivyo hii ilikuwa haraka kidogo
kuja juu katika Mac OS

210
00:10:38,918 --> 00:10:41,840
au katika Windows wakati kuungana kwa
mtandao wa Wi-Fi kwa mara ya kwanza.

211
00:10:41,840 --> 00:10:45,480
Na nilikuwa na kusoma kwa njia masharti yao
na hali na hatimaye bonyeza OK.

212
00:10:45,480 --> 00:10:47,140
Na kisha mimi aliruhusiwa kuendelea.

213
00:10:47,140 --> 00:10:51,510
>> Basi hebu kuanza kufikiri upya nini yote ya
hii ina maana na kwa tena kuchukua kwa

214
00:10:51,510 --> 00:10:54,800
nafasi gani watu wanatuambia wakati sisi
kukutana ni pamoja na teknolojia mbalimbali.

215
00:10:54,800 --> 00:10:57,520
Hivyo moja, ni nini maana kwamba
hii ni salama internet portal?

216
00:10:57,520 --> 00:11:00,260

217
00:11:00,260 --> 00:11:02,557
Nini inaweza Bertucci ya
kuwa kumtuliza yangu ya?

218
00:11:02,557 --> 00:11:04,890
Watazamaji: pakiti kutumwa
na kurudi ni encrypted.

219
00:11:04,890 --> 00:11:05,030
DAVID Malan: Mwema.

220
00:11:05,030 --> 00:11:07,470
Pakiti kupelekwa nyuma
na huko ni encrypted.

221
00:11:07,470 --> 00:11:08,984
Ni kwamba kwa kweli kesi?

222
00:11:08,984 --> 00:11:12,150
Kama kwamba walikuwa kesi, gani mimi
una kufanya au kitu gani mimi kujua?

223
00:11:12,150 --> 00:11:14,486
Vizuri, utaweza kuona kidogo
kufuli icon katika Mac OS

224
00:11:14,486 --> 00:11:16,860
au katika Windows akisema kwamba
kuna kweli baadhi encryption

225
00:11:16,860 --> 00:11:17,818
au scrambling kinachoendelea.

226
00:11:17,818 --> 00:11:20,970
Lakini kabla unaweza kutumia encrypted
portal au Wi-Fi uhusiano, nini

227
00:11:20,970 --> 00:11:23,300
je, una kawaida aina katika?

228
00:11:23,300 --> 00:11:23,890
Password.

229
00:11:23,890 --> 00:11:26,570
Najua hakuna password nyingine, wala
je, mimi aina password yoyote kama hiyo.

230
00:11:26,570 --> 00:11:27,530
Mimi tu clicked sawa.

231
00:11:27,530 --> 00:11:29,360
Hivyo hii ni kabisa maana.

232
00:11:29,360 --> 00:11:31,400
Hii si salama internet portal.

233
00:11:31,400 --> 00:11:34,500
Hii ni 100% salama internet portal.

234
00:11:34,500 --> 00:11:38,290
Kuna kabisa hakuna kuficha kwenda
juu, na kwamba wote ni kuifanya kupata

235
00:11:38,290 --> 00:11:41,660
ni kwamba mitatu neno maneno
juu ya screen huko.

236
00:11:41,660 --> 00:11:44,027
>> Hivyo kwamba maana yoyote ile,
lazima, teknolojia.

237
00:11:44,027 --> 00:11:45,860
Na kidogo zaidi
inatia mashaka, kama wewe kweli

238
00:11:45,860 --> 00:11:48,560
kusoma kwa njia ya sheria na masharti,
ambayo ni ya kushangaza someka,

239
00:11:48,560 --> 00:11:50,070
ilikuwa Haya "wewe
kuelewa kwamba tunayo

240
00:11:50,070 --> 00:11:53,380
Haki ya kuingia au kufuatilia trafiki kwa
kuhakikisha maneno haya ni kuwa na kufuatiwa. "

241
00:11:53,380 --> 00:11:56,940
Hivyo hiyo ni kidogo creepy, ikiwa Bertucci ya
ni kuangalia biashara yangu trafiki.

242
00:11:56,940 --> 00:11:59,480
Lakini wengi makubaliano yoyote ambayo
umefanya upofu clicked kupitia

243
00:11:59,480 --> 00:12:01,220
ina hakika alisema kuwa kabla.

244
00:12:01,220 --> 00:12:03,370
>> Kwa hiyo kile gani kwamba kwa kweli
maana teknolojia?

245
00:12:03,370 --> 00:12:05,839
Hivyo kama kuna baadhi creepy
guy au mwanamke katika nyuma

246
00:12:05,839 --> 00:12:07,880
ambaye ni, kama, ufuatiliaji
trafiki wote biashara,

247
00:12:07,880 --> 00:12:12,120
ni jinsi yeye au yeye kupata
kwamba taarifa hasa?

248
00:12:12,120 --> 00:12:14,900
Je, ni teknolojia
ina maana kupitia ambayo

249
00:12:14,900 --> 00:12:17,200
kwamba person-- au
Maana adui, zaidi generally--

250
00:12:17,200 --> 00:12:18,450
Unaweza kuwa na kuangalia trafiki wetu?

251
00:12:18,450 --> 00:12:21,366
>> Naam, kama hakuna kuficha, kile
aina ya mambo wao wanaweza vuta,

252
00:12:21,366 --> 00:12:24,622
hivyo kusema, aina ya kuchunguza katika hewa.

253
00:12:24,622 --> 00:12:25,580
Kitu gani ukiangalia?

254
00:12:25,580 --> 00:12:25,830
Yeah?

255
00:12:25,830 --> 00:12:28,790
>> Watazamaji: pakiti kupelekwa
kutoka kwa kompyuta yako na router?

256
00:12:28,790 --> 00:12:29,100

257
00:12:29,100 --> 00:12:31,160
Pakiti kupelekwa kutoka
kompyuta kwa router yako.

258
00:12:31,160 --> 00:12:32,540
Hivyo unaweza kukumbuka wakati
tulikuwa katika New Haven,

259
00:12:32,540 --> 00:12:36,047
sisi kupita bahasha hizo, kimwili,
katika watazamaji kuiwakilisha

260
00:12:36,047 --> 00:12:37,380
data ya kwenda kwa njia ya mtandao.

261
00:12:37,380 --> 00:12:40,940
Na hakika, kama sisi walikuwa kutupa
yao kwa njia ya watazamaji wirelessly

262
00:12:40,940 --> 00:12:45,631
kufikia marudio yao, mtu yeyote anaweza
aina ya kunyakua hiyo na kufanya nakala yake

263
00:12:45,631 --> 00:12:47,630
na kwa kweli kuona nini
ndani ya kwamba bahasha.

264
00:12:47,630 --> 00:12:49,630
>> Na, bila shaka, nini
ndani ya bahasha hizi

265
00:12:49,630 --> 00:12:53,390
ni idadi yoyote ya mambo,
ikiwa ni pamoja na anwani ya IP

266
00:12:53,390 --> 00:12:55,910
kwamba wewe ni kujaribu
upatikanaji au jina jeshi,

267
00:12:55,910 --> 00:12:59,070
kama www.harvard.edu au
yale.edu kwamba wewe ni kujaribu

kupata au kitu kingine kabisa.

269
00:13:00,840 --> 00:13:04,740
Aidha, njia, too-- unajua kutoka
pset sita kwamba ndani ya maombi HTTP

270
00:13:04,740 --> 00:13:08,130
ni kupata kufyeka something.html.

271
00:13:08,130 --> 00:13:12,010
Hivyo kama wewe ni kutembelea ukurasa maalum,
kupakua picha maalum au video,

272
00:13:12,010 --> 00:13:14,780
wote wa habari kwamba
ni ndani ya kwamba pakiti.

273
00:13:14,780 --> 00:13:19,186
Na hivyo mtu yeyote pale katika Bertucci ya can
kuwa na kuangalia kwamba data huo sana.

274
00:13:19,186 --> 00:13:21,310
Naam, ni nini ni baadhi ya wengine
vitisho pamoja mistari haya

275
00:13:21,310 --> 00:13:24,590
kuwa kukumbuka ya kabla
tu kuanza kukubali kama kweli

276
00:13:24,590 --> 00:13:26,980
nini mtu kama
Bertucci ya tu atakwambia?

277
00:13:26,980 --> 00:13:29,350
Vizuri, hii ilikuwa article--
mfululizo wa makala

278
00:13:29,350 --> 00:13:31,260
waliotoka tu miezi michache nyuma.

279
00:13:31,260 --> 00:13:34,450
Chuki yote siku hizi ni
hizi newfangled smart TV.

280
00:13:34,450 --> 00:13:37,787
Nini TV smart, kama wameweza
kusikia yao au kuwa moja nyumbani?

281
00:13:37,787 --> 00:13:39,120
Watazamaji: kuunganishwa mtandao?

282
00:13:39,120 --> 00:13:40,828
DAVID Malan: Yeah,
kuunganishwa mtandao.

283
00:13:40,828 --> 00:13:44,030
Hivyo kwa ujumla, TV smart ni
TV na internet kuunganishwa

284
00:13:44,030 --> 00:13:46,267
na user kweli crappy
interface kwamba inafanya

285
00:13:46,267 --> 00:13:49,100
ni vigumu kweli kutumia mtandao
kwa sababu una kutumia, kama, juu,

286
00:13:49,100 --> 00:13:51,260
chini, kushoto, na haki au kitu
juu ya utawala wako kijijini tu

287
00:13:51,260 --> 00:13:54,150
kupata mambo ambayo ni sana
urahisi zaidi kufanyika juu ya mbali.

288
00:13:54,150 --> 00:13:58,870
>> Lakini inatia mashaka zaidi kuhusu TV smart,
na Samsung TV katika kesi hii,

289
00:13:58,870 --> 00:14:03,290
ni kwamba Samsung TV na wengine
siku hizi kuja na vifaa fulani

290
00:14:03,290 --> 00:14:06,280
kujenga nini wanadai ni
bora user interface kwa ajili yenu.

291
00:14:06,280 --> 00:14:09,070
Hivyo moja, unaweza kuzungumza na
baadhi ya TV yako siku hizi,

292
00:14:09,070 --> 00:14:13,640
si tofauti na Siri au yoyote ya
EQUIVALENTS mengine kwenye simu za mkononi.

293
00:14:13,640 --> 00:14:15,530
Hivyo unaweza kusema amri,
kama mabadiliko channel,

294
00:14:15,530 --> 00:14:18,006
kuongeza kiasi, kugeuka mbali, au kama.

295
00:14:18,006 --> 00:14:19,880
Lakini nini maana
ya kwamba mantiki?

296
00:14:19,880 --> 00:14:23,400
Kama nimepata TV katika maisha yako
chumba au TV kwenye miguu ya kitanda yako

297
00:14:23,400 --> 00:14:25,299
na usingizi kwa,
nini maana?

298
00:14:25,299 --> 00:14:25,799
Yeah?

299
00:14:25,799 --> 00:14:29,222
>> Watazamaji: Ni lazima kuna kitu
kwenda katika kupitia utaratibu

300
00:14:29,222 --> 00:14:30,917
kuchunguza hotuba yako.

301
00:14:30,917 --> 00:14:31,667
DAVID Malan: Yeah.

302
00:14:31,667 --> 00:14:34,601

kutumwa kupitia mtandao.

303

304
00:14:36,617 --> 00:14:37,450
DAVID Malan: Kwa hakika.

305
00:14:37,450 --> 00:14:40,420
Kama una kipaza sauti kujengwa
ndani ya TV na madhumuni yake katika maisha

306
00:14:40,420 --> 00:14:43,550
ni, kwa kubuni, kuwasikiliza
kwako na kukabiliana na wewe,

00:14:43,550 --> 00:14:46,660
ni hakika kwenda kuwa
kusikiliza kila kitu kusema

308
00:14:46,660 --> 00:14:50,140
na kisha kutafsiri kwamba kwa
baadhi iliyoingia maelekezo.

309
00:14:50,140 --> 00:14:54,190
Lakini samaki ni kwamba wengi wa hawa
TV si kikamilifu smart wenyewe.

310
00:14:54,190 --> 00:14:56,430
Wao ni tegemezi sana kwa
kwamba uhusiano wa internet.

311
00:14:56,430 --> 00:14:58,560
>> Sana kama Siri, wakati
kuongea katika simu yako,

312
00:14:58,560 --> 00:15:01,660
haraka inapeleka kwamba data katika
biashara kwa watumishi Apple,

313
00:15:01,660 --> 00:15:05,551
kisha anapata nyuma majibu, literally
ni Nokia TV na EQUIVALENTS

314
00:15:05,551 --> 00:15:07,925
kutuma tu kila kitu uko
akisema katika chumba yako ya kuishi

315
00:15:07,925 --> 00:15:12,040
au chumba cha kulala kwa watumishi wao tu
kuchunguza yeye kusema, kurejea kwenye TV

316
00:15:12,040 --> 00:15:13,030
au kuzima TV?

317
00:15:13,030 --> 00:15:15,052
Na Mungu anayajua
mwingine anaweza kutamkwa.

318
00:15:15,052 --> 00:15:17,010
Sasa, kuna baadhi ya njia
kukabiliana na hii, sawa?

319
00:15:17,010 --> 00:15:20,730
Kama nini na nini Siri
anafanya Google na wengine kufanya

320
00:15:20,730 --> 00:15:23,630
angalau kulinda dhidi ya
kwamba hatari kwamba wao ni

321
00:15:23,630 --> 00:15:26,491
kusikiliza kila kitu kabisa?

322
00:15:26,491 --> 00:15:28,240
Ina kuwa kuanzishwa
kwa kusema kitu

323
00:15:28,240 --> 00:15:32,580
kama, hey, Siri, au hi Google au
kama au sawa, Google au kama.

324
00:15:32,580 --> 00:15:35,180
>> Lakini sisi wote tunajua kwamba wale
Maneno aina ya Suck, sawa?

325
00:15:35,180 --> 00:15:37,842
Kama nilikuwa tu sitting--
kweli mara ya mwisho

326
00:15:37,842 --> 00:15:41,050
Nilikuwa katika masaa ya ofisi katika Yale, nadhani,
Jason au mmoja wa TFS naendelea kunguruma,

327
00:15:41,050 --> 00:15:44,000
kama, hey, Siri, hey, Siri
na hivyo kufanya simu yangu

328
00:15:44,000 --> 00:15:46,460
kufanya mambo kwa sababu alikuwa pia
kupakana na simu yangu halisi.

329
00:15:46,460 --> 00:15:47,550
Lakini kinyume ni kweli, pia.

330
00:15:47,550 --> 00:15:49,740
Wakati mwingine mambo hayo tu
teke juu kwa sababu ni kasoro.

331
00:15:49,740 --> 00:15:51,640
Na hakika, asili
Lugha processing--

332
00:15:51,640 --> 00:15:54,660
kuelewa phrasing binadamu na
kisha kufanya kitu kulingana na it--

333
00:15:54,660 --> 00:15:55,970
Ni hakika si mkamilifu.

334
00:15:55,970 --> 00:15:58,220
>> Sasa, mbaya lakini, baadhi
ya unaweza kuwa na kuonekana

335
00:15:58,220 --> 00:16:01,939
au kuwa na TV ambapo unaweza kufanya
mambo ya kijinga au mpya wenye umri kama hii

336
00:16:01,939 --> 00:16:04,855
na mabadiliko ya njia ya kushoto au
hii na mabadiliko ya njia na haki

337
00:16:04,855 --> 00:16:07,400
au kupunguza kiasi au kuongeza kiasi.

338
00:16:07,400 --> 00:16:09,480
Lakini hiyo ina maana gani TV ina?

339
00:16:09,480 --> 00:16:12,610
Kamera alisema katika wewe
wakati wote iwezekanavyo.

340
00:16:12,610 --> 00:16:15,741
>> Na kwa kweli, brouhaha karibu Nokia
TV ambayo walichukua baadhi Flack

341
00:16:15,741 --> 00:16:18,490
ni kwamba kama wewe kusoma sheria na
masharti ya TV-- kitu

342
00:16:18,490 --> 00:16:22,300
wewe hakika kamwe kusoma wakati unpacking
TV yako kwa time-- kwanza iliyoingia

343
00:16:22,300 --> 00:16:26,700
katika kulikuwa na disclaimer kidogo
akisema sawa na,

344
00:16:26,700 --> 00:16:30,050
a unaweza si unataka kuwa na binafsi
Mazungumzo mbele ya TV hii.

345
00:16:30,050 --> 00:16:31,300
Na hiyo ndiyo inapunguza kwa.

346
00:16:31,300 --> 00:16:33,230
>> Lakini unapaswa hata
haja ya kuambiwa kuwa.

347
00:16:33,230 --> 00:16:35,063
Unapaswa kuwa na uwezo wa
kudai kutoka ukweli

348
00:16:35,063 --> 00:16:38,610
kwamba kipaza sauti na kamera halisi
akionyesha mimi wakati wote

349
00:16:38,610 --> 00:16:40,940
labda ni mbaya zaidi kuliko mema.

350
00:16:40,940 --> 00:16:43,600
Na kusema ukweli, Nasema hivi
kiasi fulani kinafiki.

351
00:16:43,600 --> 00:16:47,080
Mimi literally kuwa, mbali na kamera hizo,
Nina vidogo kamera kidogo hapa

352
00:16:47,080 --> 00:16:47,680
katika laptop yangu.

353
00:16:47,680 --> 00:16:48,950
Mimi na mwingine mmoja zaidi ya hapa.

354
00:16:48,950 --> 00:16:50,842
Nina katika wangu
simu za mkononi kwa pande zote mbili.

355
00:16:50,842 --> 00:16:52,550
Hivyo nisije kuiweka chini
njia sahihi, wao

356
00:16:52,550 --> 00:16:54,550
bado anaweza kuangalia mimi na kunisikiliza.

357
00:16:54,550 --> 00:16:56,430
>> Na hii yote inaweza kuwa
kinachotokea wakati wote.

358
00:16:56,430 --> 00:17:01,240
Basi nini kuacha iPhone yangu au Android
simu kutoka kwa kufanya hii wakati wote?

359
00:17:01,240 --> 00:17:04,099
Tunajuaje kwamba Apple na
baadhi mtu creepy katika Google,

360
00:17:04,099 --> 00:17:06,560
si kusikiliza katika kwa
mazungumzo haya sana

361
00:17:06,560 --> 00:17:09,404
kwa njia ya simu au mazungumzo
Nina nyumbani au kazini?

362
00:17:09,404 --> 00:17:11,220
>> Watazamaji: Kwa sababu maisha yetu
si kwamba kuvutia.

363
00:17:11,220 --> 00:17:13,511
>> DAVID Malan: Kwa sababu yetu
maisha si kwamba kuvutia.

364
00:17:13,511 --> 00:17:15,400
Kwamba kweli ni majibu halali.

365
00:17:15,400 --> 00:17:17,500
Kama sisi siyo wasiwasi
kuhusu tishio fulani,

366
00:17:17,500 --> 00:17:19,520
kuna aina ya nani
anayejali nyanja hiyo.

367
00:17:19,520 --> 00:17:22,000
Umri mdogo kwangu si kwenda
kwa kweli kuwa lengo.

368
00:17:22,000 --> 00:17:23,300
Lakini kwa hakika naweza.

369
00:17:23,300 --> 00:17:26,140
>> Na hivyo hata kama wewe kuona baadhi
mambo cheesy juu ya TV na sinema,

370
00:17:26,140 --> 00:17:29,830
kama, loo, tuangalie kwenye gridi and--
kama Batman gani hii mengi, kwa kweli,

371
00:17:29,830 --> 00:17:32,920
na kwa kweli unaweza kuona Gotham, nini
kinachoendelea kwa njia ya simu za mikononi ya watu

372
00:17:32,920 --> 00:17:33,420
au kama.

373
00:17:33,420 --> 00:17:37,410
Baadhi ya kwamba ni Futuristic kidogo,
lakini sisi ni pretty much pale siku hizi.

374
00:17:37,410 --> 00:17:40,030
>> Karibu wote wa kwetu ni
kutembea karibu na GPS

375
00:17:40,030 --> 00:17:42,130
transponders kwamba ni
kuwaambia Apple na Google

376
00:17:42,130 --> 00:17:44,460
na kila mtu mwingine kwamba anataka
kujua ambapo sisi ni katika dunia.

377
00:17:44,460 --> 00:17:45,340
Tuna kipaza sauti.

378
00:17:45,340 --> 00:17:46,140
Tuna kamera.

379
00:17:46,140 --> 00:17:50,410
Sisi ni kuwaambia mambo kama Snapchat na
maombi mengine kila mtu tunajua,

380
00:17:50,410 --> 00:17:53,090
wote wa namba za simu zao,
wote wa anwani zao email.

381
00:17:53,090 --> 00:17:56,650
Na hivyo tena, mmoja wa takeaways
leo, pengine, ni angalau pause

382
00:17:56,650 --> 00:17:58,830
kidogo kabla
tu upofu kusema, OK

383
00:17:58,830 --> 00:18:00,590
wakati unataka
urahisi wa Snapchat

384
00:18:00,590 --> 00:18:02,203
kujua nani wote wa rafiki yako ni.

385
00:18:02,203 --> 00:18:05,440
Lakini kinyume chake, sasa Snapchat
anajua kila mtu unajua

386
00:18:05,440 --> 00:18:08,140
na maelezo yoyote kidogo waweza
kuwa alifanya katika mawasiliano yako.

387
00:18:08,140 --> 00:18:09,850
>> Hivyo hii ilikuwa moja kwa wakati, pia.

388
00:18:09,850 --> 00:18:12,780
Miezi michache nyuma, Snapchat
yenyewe haikuwa kuathirika.

389
00:18:12,780 --> 00:18:14,780
Lakini kumekuwa na baadhi ya
maombi ya tatu

390
00:18:14,780 --> 00:18:18,220
kuwa alifanya hivyo rahisi kuokoa
snaps Na kukamata alikuwa

391
00:18:18,220 --> 00:18:21,520
kwamba kuwa huduma tatu
ilikuwa yenyewe kuathirika,

392
00:18:21,520 --> 00:18:25,200
katika sehemu kwa sababu huduma Snapchat ya
mkono kipengele kwamba wao pengine

393
00:18:25,200 --> 00:18:28,075
haipaswi kuwa, ambayo kuruhusiwa kwa
archiving hii na mtu wa tatu.

394
00:18:28,075 --> 00:18:32,740
>> Na tatizo ni kwamba archive
ya, kama, 90000 snaps, nadhani,

395
00:18:32,740 --> 00:18:34,690
walikuwa hatimaye kuathirika.

396
00:18:34,690 --> 00:18:37,980
Na hivyo unaweza kuchukua baadhi ya faraja katika
mambo kama Snapchat kuwa ephemeral,

397
00:18:37,980 --> 00:18:38,480
sawa?

398
00:18:38,480 --> 00:18:41,650
Una sekunde saba kuangalia
kwamba ujumbe muafaka au kumbuka,

399
00:18:41,650 --> 00:18:42,640
na kisha kutoweka.

400
00:18:42,640 --> 00:18:44,770
Lakini moja, wengi wenu
pengine figured nje

401
00:18:44,770 --> 00:18:48,620
jinsi ya kuchukua viwambo kwa sasa, ambayo
ni njia rahisi zaidi kukwepa hilo.

402
00:18:48,620 --> 00:18:53,050
Lakini wawili, kuna kitu kuacha
kampuni au mtu ni kwenye mtandao

403
00:18:53,050 --> 00:18:56,160
kutoka kukamata kwamba
data, uwezekano, kama vile.

404
00:18:56,160 --> 00:18:59,640
>> Hivyo hii ilikuwa literally
tu siku moja au mbili zilizopita.

405
00:18:59,640 --> 00:19:03,850
Hii ilikuwa nzuri makala ya kichwa cha habari juu ya
tovuti online. "Epic Fail-- Power minyoo

406
00:19:03,850 --> 00:19:07,767
Ransomware Ajali Huharibu
Mhasiriwa Takwimu Wakati Fiche. "

407
00:19:07,767 --> 00:19:10,100
Hivyo nyingine ripped kutoka
vichwa vya habari aina ya kitu hapa.

408
00:19:10,100 --> 00:19:11,808
Hivyo unaweza kuwa
sikia zisizo, ambayo

409
00:19:11,808 --> 00:19:15,380
ni kwa makusudi software-- programu mbaya
kwamba watu wenye kupita kiasi bure wakati

410
00:19:15,380 --> 00:19:15,900
kuandika.

411
00:19:15,900 --> 00:19:18,880
Na wakati mwingine, ni tu hana
mambo ya kijinga kama kufuta mafaili

412
00:19:18,880 --> 00:19:20,830
au kutuma barua taka au kama.

413
00:19:20,830 --> 00:19:23,880
>> Lakini wakati mwingine, na inazidi,
ni ya kisasa zaidi, sawa?

414
00:19:23,880 --> 00:19:26,000
Wewe wote tunajua jinsi ya
dabble katika encryption.

415
00:19:26,000 --> 00:19:27,950
Na Kaisari na Vigenere
si super salama,

416
00:19:27,950 --> 00:19:30,575
lakini kuna wale wengine, hakika,
ambazo ni za kisasa zaidi.

417
00:19:30,575 --> 00:19:33,700
Na hivyo kile adui hakufanya
ilikuwa aliandika kipande cha zisizo

418
00:19:33,700 --> 00:19:36,200
kwamba kwa namna fulani kuambukizwa
rundo la kompyuta za watu.

419
00:19:36,200 --> 00:19:39,830
Lakini alikuwa aina ya idiot na
aliandika buggy toleo la zisizo hii

420
00:19:39,830 --> 00:19:45,480
kiasi kwamba wakati yeye au yeye
kutekelezwa code-- loo, tuko

421
00:19:45,480 --> 00:19:49,280
kupata kura of-- pole.

422
00:19:49,280 --> 00:19:51,580
Sisi ni kupata mengi ya
hits juu ya kipaza sauti.

423
00:19:51,580 --> 00:19:52,260
SAWA.

424
00:19:52,260 --> 00:19:55,280
>> Kwa hiyo kile Tatizo ni kwamba
yeye au yeye aliandika baadhi ya kanuni mbaya.

425
00:19:55,280 --> 00:19:58,500
Na hivyo yanayotokana
pseudorandomly ufunguo encryption

426
00:19:58,500 --> 00:20:00,920
na ambayo encrypt
data ya mtu kwa nia mbaya,

427
00:20:00,920 --> 00:20:03,580
na kisha ajali kurusha
ule ufunguo wa mlango encryption.

428
00:20:03,580 --> 00:20:06,110
Hivyo athari za hii
zisizo hakuwa kama ilivyokusudiwa,

429
00:20:06,110 --> 00:20:09,750
na takwimu fidia ya mtu na
encrypting yake au gari yake ngumu

430
00:20:09,750 --> 00:20:13,930
na kisha wanatarajia $ 800 Marekani kwa malipo
kwa encryption muhimu, ambapo kiwango

431
00:20:13,930 --> 00:20:15,970
muathirika anaweza
decrypt data yake.

432
00:20:15,970 --> 00:20:18,810
Badala yake, mtu mbaya tu
encrypted data zote

433
00:20:18,810 --> 00:20:21,800
kwenye gari zao ngumu, ajali
kufutwa ufunguo encryption,

434
00:20:21,800 --> 00:20:23,390
na got hakuna fedha nje ya hiyo.

435
00:20:23,390 --> 00:20:26,850
Lakini hii pia ina maana kwamba waathirika ni
kweli muathirika kwa sababu sasa yeye au yeye

436
00:20:26,850 --> 00:20:30,450
hawezi kupona yoyote ya data isipokuwa
wao kweli kuwa baadhi umri wa kwenda shule

437
00:20:30,450 --> 00:20:31,660
Backup yake.

438
00:20:31,660 --> 00:20:35,840
>> Hivyo hapa pia ni aina ya ukweli
kwamba utasikia kusoma kuhusu siku hizi.

439
00:20:35,840 --> 00:20:37,340
Na jinsi gani unaweza kulinda dhidi ya hili?

440
00:20:37,340 --> 00:20:39,890
Naam, hii ni can nzima
ya minyoo, pun hakuna lengo,

441
00:20:39,890 --> 00:20:41,950
kuhusu virusi na minyoo na kadhalika.

442
00:20:41,950 --> 00:20:45,090
Na kuna shaka programu
na ambayo unaweza kutetea mwenyewe.

443
00:20:45,090 --> 00:20:47,500
Lakini bora kuliko hayo ni
tu kuwa smart kuhusu hilo.

444
00:20:47,500 --> 00:20:51,680
>> Kwa kweli, mimi have not hii ni moja ya
hizi kufanya kama mimi kusema, si kama mimi kufanya mambo,

445
00:20:51,680 --> 00:20:54,950
perhaps-- mimi si kweli kutumika
antivirus programu katika miaka

446
00:20:54,950 --> 00:20:58,700
kwa sababu kama wewe kwa ujumla kujua nini cha
kuangalia, unaweza kulinda dhidi ya

447
00:20:58,700 --> 00:20:59,720
kila kitu juu yako mwenyewe.

448
00:20:59,720 --> 00:21:02,870
Na kwa kweli, wakati hapa katika
Harvard-- kulikuwa na mdudu au suala

449
00:21:02,870 --> 00:21:04,880
wiki iliyopita ambapo Harvard
ni wazi, kama,

450
00:21:04,880 --> 00:21:06,690
ufuatiliaji kura ya trafiki mtandao.

451
00:21:06,690 --> 00:21:08,482
Na nyote hata
kutembelea tovuti CS50

452
00:21:08,482 --> 00:21:11,315
anaweza kuwa wamezipata msemo tahadhari
kwamba huwezi kutembelea tovuti hii.

453
00:21:11,315 --> 00:21:12,180
Ni si salama.

454
00:21:12,180 --> 00:21:13,730
Lakini kama wewe walijaribu kutembelea
Google au maeneo mengine,

455
00:21:13,730 --> 00:21:15,270
pia, hizo, pia, walikuwa salama.

456
00:21:15,270 --> 00:21:17,990
>> Hii ni kwa sababu Kikuu cha Harvard, pia, ina
aina fulani ya mfumo wa filtration

457
00:21:17,990 --> 00:21:21,860
kwamba ni kuweka jicho nje ya
tovuti uwezekano wa makusudi

458
00:21:21,860 --> 00:21:23,620

Hakika, kwa kitu
kama hii, ambapo Brits

wa takwimu, ambapo inaweza kuwa watakuwa kuja kutoka?

bila shaka, siyo tu

ni aina ya jamii haijulikani au
mikataba undisclosed,

ambayo kushika adui nje.

mbili, nyuma kama wewe kukabiliana

Na kama tumekuwa anashangaa yote haya
muda gani nywila halisi ilivyokuwa,

561
00:26:12,730 --> 00:26:14,934
hii ni nini, kwa kweli,
wao decrypt kwa, ambayo

cute maana hapa au katika New Haven.

565

wao wote, angalau hapa,

566
00:26:26,510 --> 00:26:28,619
ni pretty mfupi, mzuri guessable.

567
00:26:28,619 --> 00:26:31,160
I mean, kulingana na orodha hapa,
ambayo ni rahisi labda

568

Na ni just-- moja, ni
nenosiri kawaida sana.

573

Kwa kweli, kila mwaka kuna orodha ya
nywila ya kawaida katika dunia.

kwa ujumla ni atop orodha hiyo.

Mbili, ni katika kamusi.

576
00:26:48,425 --> 00:26:50,310
Na unajua na tatizo
kuweka tano kwamba siyo

00:26:50,310 --> 00:26:52,110
kwamba hard-- inaweza kuwa
kidogo wakati consuming--

578
00:26:52,110 --> 00:26:54,440
lakini siyo kwamba ni vigumu mzigo
kamusi kubwa katika kumbukumbu

Yeah?

583
00:27:02,084 --> 00:27:04,036

Baadhi yao chumvi mbalimbali.

590
00:27:24,820 --> 00:27:28,240
Hivyo unaweza kweli kuepuka kuwa
marudio ya baadhi ya wahusika tu

591
00:27:28,240 --> 00:27:30,220

Jambo rahisi sana nadhani.

593

na wote wa nywila hizo

594
00:27:35,770 --> 00:27:39,982
ni kwamba wao ni wote tu kwa kutumia 26
wahusika inawezekana, au labda 52

na kisha barua 10.

Mimi si kutumia wahusika yoyote funky.

unafikiri wewe kuwa wajanja, ingawa, na
kuwa sifuri kwa O katika password yako

or-- sawa, nikaona mtu tabasamu.

600
00:27:55,570 --> 00:28:00,790
Hivyo mtu ana sifuri kwa
O katika nenosiri yake.

601

>> Wewe si kweli kuwa kama
wajanja kama unaweza kufikiri, haki?

602
00:28:03,720 --> 00:28:06,150
Kwa sababu kama zaidi ya moja ya
sisi ni kufanya hivi kwa room--

603
00:28:06,150 --> 00:28:09,400

je adui una kufanya?

605

Tu kuongeza zeros na ndio
na wanandoa wa other--

dhidi nywila

Hivyo mimi literally tu got hii
katika Inbox yangu siku nne zilizopita.

614
00:28:34,640 --> 00:28:38,010
Hii ni kutokana na Brittany, ambaye
inaonekana anafanya kazi katika harvard.edu.

615
00:28:38,010 --> 00:28:40,080
Na yeye aliandika mimi kama
webmail mtumiaji. "Sisi tu

616
00:28:40,080 --> 00:28:41,880
niliona kuwa email yako
akaunti ilikuwa watumiaji

617
00:28:41,880 --> 00:28:43,796
kwenye kompyuta nyingine
katika eneo tofauti,

618
00:28:43,796 --> 00:28:46,410
na wewe ni kuthibitisha
utambulisho wako binafsi. "

619
00:28:46,410 --> 00:28:50,810
>> Hivyo ufadhili katika barua pepe nyingi kama
hii, ambayo ni mifano ya hadaa

620
00:28:50,810 --> 00:28:56,310
attacks-- P-H-I-S-H-I-N-G-- ambapo
mtu ni kujaribu kuvua na kupata baadhi ya

621
00:28:56,310 --> 00:28:59,560
Maelezo nje ya wewe,
ujumla kwa barua pepe kama hii.

622
00:28:59,560 --> 00:29:02,320
Lakini ni nini baadhi ya telltale
dalili kwamba hii si, kwa kweli,

623
00:29:02,320 --> 00:29:04,345
email halali kutoka
Chuo Kikuu cha Harvard?

624
00:29:04,345 --> 00:29:06,860

625
00:29:06,860 --> 00:29:09,080
Nini hiyo?

626
00:29:09,080 --> 00:29:11,380
>> Hivyo sarufi mbaya,
mtaji weird,

627
00:29:11,380 --> 00:29:13,540
jinsi baadhi ya barua ni
mtaji katika maeneo fulani.

628
00:29:13,540 --> 00:29:15,900
Kuna baadhi indentation isiyo ya kawaida
katika michache ya maeneo.

629
00:29:15,900 --> 00:29:18,220
Nini kingine?

630
00:29:18,220 --> 00:29:19,470
Nini hiyo?

631
00:29:19,470 --> 00:29:22,230
Naam, kwamba hakika
helps-- kubwa njano sanduku

632
00:29:22,230 --> 00:29:25,900
kwamba anasema hii inaweza kuwa barua taka kutoka
Google, ambayo ni hakika kusaidia.

633
00:29:25,900 --> 00:29:28,100
>> Hivyo kuna mengi ya ishara telltale hapa.

634
00:29:28,100 --> 00:29:30,700
Lakini ukweli ni hizi
barua pepe lazima kazi, haki?

635
00:29:30,700 --> 00:29:34,970
Ni pretty nafuu, kama siyo bure, kutuma
nje mamia au maelfu ya barua pepe.

636
00:29:34,970 --> 00:29:37,315
Na si tu kwa kutuma
yao nje ya ISP yako mwenyewe.

637
00:29:37,315 --> 00:29:39,930
Moja ya mambo ambayo
zisizo gani huwa na do--

638
00:29:39,930 --> 00:29:43,260
hivyo virusi na minyoo kwamba ajali
kuwaambukiza au kompyuta kwa sababu wameweza

639
00:29:43,260 --> 00:29:47,390
imeandikwa na adversaries-- moja ya
mambo ya wao kufanya ni churn nje tu taka.

640
00:29:47,390 --> 00:29:49,860
>> Kwa hiyo kile kuna gani zipo
katika dunia, kwa kweli,

641
00:29:49,860 --> 00:29:52,706
ni mambo kuitwa botnets,
ambayo ni njia dhana ya kusema

642
00:29:52,706 --> 00:29:55,080
kwamba watu wenye bora coding
ujuzi kuliko mtu ambaye

643
00:29:55,080 --> 00:29:59,040
aliandika kwamba buggy toleo la programu,
kwa kweli imeandikwa programu

644
00:29:59,040 --> 00:30:03,080
kwamba watu kama sisi unsuspectingly
kufunga kwenye kompyuta yetu

645
00:30:03,080 --> 00:30:05,830
na kisha kuanza mbio nyuma
pazia, unbeknownst kwetu.

646
00:30:05,830 --> 00:30:08,850
Na wale zisizo
mipango intercommunicate.

647
00:30:08,850 --> 00:30:11,350
Wao kuunda mtandao,
botnet kama wewe.

648
00:30:11,350 --> 00:30:13,820
Na kwa ujumla, wengi
kisasa ya wapinzani

649
00:30:13,820 --> 00:30:17,820
ina aina fulani ya kijijini udhibiti wa
maelfu, kama si mamia ya maelfu,

650
00:30:17,820 --> 00:30:20,800
ya kompyuta kwa kutuma tu
ujumbe kwenye mtandao

651
00:30:20,800 --> 00:30:24,620
kwamba wote wa roboti hizo, hivyo kusema,
wana uwezo wa kusikia au mara kwa mara

652
00:30:24,620 --> 00:30:29,430
ombi kutoka kwa baadhi Tovuti kati na kisha
inaweza kudhibitiwa apeleke barua taka.

653
00:30:29,430 --> 00:30:32,210
>> Na hawa barua taka mambo inaweza kuwa
tu kuuzwa kwa mzabuni wa juu.

654
00:30:32,210 --> 00:30:34,890
Kama uko kampuni au
aina ya pindo kampuni

655
00:30:34,890 --> 00:30:38,720
hiyo haina kweli huduma kuhusu
aina ya maadili ya spamming watumiaji yako

656
00:30:38,720 --> 00:30:40,600
lakini unataka tu
kugonga nje ya watu milioni

657
00:30:40,600 --> 00:30:42,390
na matumaini kwamba 1% ya
them-- ambayo bado

658
00:30:42,390 --> 00:30:45,326
idadi nontrivial
ya uwezo buyers--

659
00:30:45,326 --> 00:30:48,450
unaweza kweli kulipa wapinzani hawa
katika aina ya nyeusi soko la aina

660
00:30:48,450 --> 00:30:50,930
apeleke spams hizi
kupitia botnets yao kwa ajili yenu.

661
00:30:50,930 --> 00:30:54,380
>> Hivyo inatosha kusema, hii si
email hasa kulazimisha.

662
00:30:54,380 --> 00:30:56,410
Lakini hata Harvard na
Yale na kama mara nyingi

663
00:30:56,410 --> 00:31:00,150
kufanya makosa, kwa kuwa
tunajua kutoka wiki chache

664
00:31:00,150 --> 00:31:04,870
nyuma kwamba unaweza kufanya
kiungo kusema www.paypal.com.

665
00:31:04,870 --> 00:31:06,440
Na inaonekana kama unaendelea huko.

666
00:31:06,440 --> 00:31:08,480
Lakini, bila shaka, ni
haina kweli kufanya hivyo.

667
00:31:08,480 --> 00:31:11,646
>> Na hivyo Harvard na Yale na wengine wana
hakika na hatia katika kipindi cha miaka

668
00:31:11,646 --> 00:31:13,650
katika kutuma barua pepe
ambazo ni halali,

669
00:31:13,650 --> 00:31:15,810
lakini wao vyenye viungo ndani yao.

670
00:31:15,810 --> 00:31:19,030
Na sisi, kama binadamu, wamekuwa
mafunzo na aina ya viongozi,

671
00:31:19,030 --> 00:31:21,997
mara nyingi kabisa, kwa kweli kufuata tu
viungo kwamba sisi kupokea katika barua pepe.

672
00:31:21,997 --> 00:31:23,580
Lakini hata ambayo si njia bora.

673
00:31:23,580 --> 00:31:25,390
Hivyo kama huna milele kupata
email kama hii

674
00:31:25,390 --> 00:31:28,339
na labda ni kutokana na Paypal au
Harvard au Yale au Benki Kuu ya Marekani

675
00:31:28,339 --> 00:31:31,630
au like-- bado unapaswa si click
kiungo, hata kama inaonekana halali.

676
00:31:31,630 --> 00:31:34,019
Unapaswa manually aina
kuwa URL mwenyewe.

677
00:31:34,019 --> 00:31:36,060
Na kusema ukweli, kwamba ni nini
msimamizi wa mfumo

678
00:31:36,060 --> 00:31:39,530
lazima kutuambia kufanya ili
sisi siyo mkadanganywa katika kufanya hivyo.

679
00:31:39,530 --> 00:31:44,930
>> Sasa, ni wangapi kati yenu, labda
kwa kuangalia chini ya kiti yako,

680
00:31:44,930 --> 00:31:46,890
kuwa siri kuandikwa mahali fulani?

681
00:31:46,890 --> 00:31:52,640
Labda katika droo katika Dorm chumba yako au
labda under-- katika mkoba mahali fulani?

682
00:31:52,640 --> 00:31:53,140
Mkoba?

683
00:31:53,140 --> 00:31:53,450
Hakuna?

684
00:31:53,450 --> 00:31:54,950
>> Watazamaji: Katika lockbox moto?

685
00:31:54,950 --> 00:31:56,690
>> DAVID Malan: Katika lockbox moto?

686
00:31:56,690 --> 00:31:57,290
SAWA.

687
00:31:57,290 --> 00:32:01,750
Hivyo hiyo ni bora kuliko
kumbuka nata juu ya kufuatilia yenu.

688
00:32:01,750 --> 00:32:04,459
Hivyo hakika, baadhi ya
wewe ni kusisitiza hakuna.

689
00:32:04,459 --> 00:32:06,750
Lakini kitu ananiambia hiyo
si lazima kesi.

690
00:32:06,750 --> 00:32:08,920
Hivyo ni jinsi kuhusu rahisi,
zaidi uwezekano question--

691
00:32:08,920 --> 00:32:13,395
jinsi wengi wenu ni kutumia
nywila sawa kwa maeneo mbalimbali?

692
00:32:13,395 --> 00:32:14,040
Oh sawa.

693
00:32:14,040 --> 00:32:14,770
Sasa sisi ni kuwa waaminifu.

694
00:32:14,770 --> 00:32:15,270
>> Sawa.

695
00:32:15,270 --> 00:32:17,560
Hivyo hiyo ni habari ya ajabu, sawa?

696
00:32:17,560 --> 00:32:21,170
Kwa sababu kama itakuwa na maana ikiwa tu mmoja wa wale
maeneo nyote ni kutumia ni kuathirika,

697
00:32:21,170 --> 00:32:23,800
sasa adui ina
upatikanaji wa data zaidi

698
00:32:23,800 --> 00:32:26,220
kuhusu wewe au zaidi uwezo ushujaa.

699
00:32:26,220 --> 00:32:27,660
Hivyo hiyo ni moja rahisi kuepuka.

700
00:32:27,660 --> 00:32:30,250
Lakini jinsi wengi wenu kuwa
pretty guessable neno la siri?

701
00:32:30,250 --> 00:32:33,344
Labda si mbaya kama hii, lakini kitu?

702
00:32:33,344 --> 00:32:34,510
Kwa baadhi ya tovuti kijinga, haki?

703
00:32:34,510 --> 00:32:36,630
Siyo hatarishi,
hana kadi ya mikopo?

704
00:32:36,630 --> 00:32:37,200
Sisi sote.

705
00:32:37,200 --> 00:32:40,990
Kama, hata mimi na nywila kwamba
pengine 12345 tu, hakika.

706
00:32:40,990 --> 00:32:44,930
Hivyo sasa jaribu kuingia ndani ya kila tovuti
unaweza kufikiria na malan@harvard.edu

707
00:32:44,930 --> 00:32:47,000
na 12,345 na kuona kama kwamba kazi.

708
00:32:47,000 --> 00:32:47,980
>> Lakini sisi kufanya hivyo, pia.

709
00:32:47,980 --> 00:32:48,650
Hivyo kwa nini?

710
00:32:48,650 --> 00:32:54,510
Kwa nini hivyo wengi wetu kuwa na aidha pretty
nywila rahisi au nywila ile ile?

711
00:32:54,510 --> 00:32:58,070
Nini ulimwengu halisi
Asili ya hili?

712
00:32:58,070 --> 00:32:59,190
Ni rahisi, sawa?

713
00:32:59,190 --> 00:33:01,372
Kama nilivyosema badala yake,
kimasomo, nyie

714
00:33:01,372 --> 00:33:03,580
lazima kweli kuwa kuchagua
nywila pseudorandom kwamba

715
00:33:03,580 --> 00:33:07,060
ni angalau 16 wahusika kwa muda mrefu na kuwa na
mchanganyiko wa herufi herufi,

716
00:33:07,060 --> 00:33:09,550
idadi, na alama,
ambao kuzimu ni kwenda

717
00:33:09,550 --> 00:33:11,650
kuwa na uwezo wa kufanya hivyo au
kukumbuka nywila hizo,

718
00:33:11,650 --> 00:33:14,820
achilia mbali kwa kila mmoja na
kila tovuti inawezekana?

719
00:33:14,820 --> 00:33:16,022
>> Basi nini ufumbuzi faida?

720
00:33:16,022 --> 00:33:17,730
Naam, moja ya
kubwa takeaways leo,

721
00:33:17,730 --> 00:33:20,500
pia, pragmatically, ingekuwa
kuwa, kwa uaminifu, na kuanza

722
00:33:20,500 --> 00:33:22,820
kutumia aina fulani ya password meneja.

723
00:33:22,820 --> 00:33:25,260
Sasa, kuna upsides na
downsides ya mambo haya, pia.

724
00:33:25,260 --> 00:33:27,259
Hizi ni mawili ambayo sisi
huwa na kupendekeza katika CS50.

725
00:33:27,259 --> 00:33:28,530
Moja ya wito kifungo 1Password.

726
00:33:28,530 --> 00:33:29,664
Moja kuitwa LastPass.

727
00:33:29,664 --> 00:33:31,330
Na baadhi yenu wanaweza kutumia haya tayari.

728
00:33:31,330 --> 00:33:33,470
Lakini ni kwa ujumla
kipande cha programu kwamba

729
00:33:33,470 --> 00:33:36,710
haina kuwezesha kuzalisha kubwa
nywila pseudorandom kwamba

730
00:33:36,710 --> 00:33:38,790
hawawezi kukumbuka kama binadamu.

731
00:33:38,790 --> 00:33:41,650
Ni maduka hayo pseudorandom
nywila katika orodha yake mwenyewe,

732
00:33:41,650 --> 00:33:45,110
hopefully juu ya bidii yako ya mtaa
drive-- encrypted, bado bora.

733
00:33:45,110 --> 00:33:46,930
Na wote, binadamu,
Una kukumbuka,

734
00:33:46,930 --> 00:33:50,879
kawaida, ni bwana mmoja password, ambayo
pengine ni kwenda kuwa super muda mrefu.

735
00:33:50,879 --> 00:33:52,420
Na labda siyo wahusika random.

736
00:33:52,420 --> 00:33:56,350
Labda ni, kama, hukumu au
aya fupi kwamba unaweza kukumbuka

737
00:33:56,350 --> 00:33:59,430
na unaweza aina mara moja kwa siku
kufungua kompyuta yako.

738
00:33:59,430 --> 00:34:02,960
>> Hivyo matumizi hasa kubwa
password kulinda na encrypt

739
00:34:02,960 --> 00:34:04,610
yote ya nywila yako mengine.

740
00:34:04,610 --> 00:34:07,110
Lakini sasa uko katika
tabia ya kutumia programu

741
00:34:07,110 --> 00:34:10,139
kama hii ya kuzalisha pseudorandom
nywila hela yote ya tovuti

742
00:34:10,139 --> 00:34:10,770
wewe kutembelea.

743
00:34:10,770 --> 00:34:13,620
Na hakika, naweza
raha kusema sasa, katika mwaka 2015,

744
00:34:13,620 --> 00:34:15,900
Sijui zaidi ya
nywila yangu tena.

745
00:34:15,900 --> 00:34:18,659
Najua bwana password yangu,
na mimi aina hiyo, kwa kutojua,

746
00:34:18,659 --> 00:34:20,449
mara moja au zaidi kwa siku.

747
00:34:20,449 --> 00:34:23,655
Lakini suala la mafanikio ni kwamba sasa, kama wapo
ya moja ya akaunti yangu ni kuathirika,

748
00:34:23,655 --> 00:34:25,780
hakuna njia ya mtu ni
kwenda kutumia akaunti hiyo

749
00:34:25,780 --> 00:34:28,969
kupata katika mwingine kwa sababu hakuna hata mmoja
nywila yangu ni sawa tena.

750
00:34:28,969 --> 00:34:32,230
>> Na hakika, hakuna mtu, hata kama yeye
au yeye anaandika ushindani programu

751
00:34:32,230 --> 00:34:35,270
kwa brute nguvu mambo na
nadhani zote passwords-- iwezekanavyo

752
00:34:35,270 --> 00:34:38,850
tabia mbaya kwamba wao ni kwenda
kuchagua 24-tabia yangu kwa muda mrefu nywila

753
00:34:38,850 --> 00:34:43,480
ni hivyo tu, hivyo chini Mimi tu si
wasiwasi kuhusu kuwa tishio tena.

754
00:34:43,480 --> 00:34:45,250
>> Basi nini biashara-off hapa?

755
00:34:45,250 --> 00:34:46,409
Hiyo inaonekana ajabu.

756
00:34:46,409 --> 00:34:48,260
Nina mambo mengi zaidi salama.

757
00:34:48,260 --> 00:34:49,400
Nini biashara-off?

758
00:34:49,400 --> 00:34:50,000
Yeah?

>> Watazamaji: Wakati.

760
00:34:51,850 --> 00:34:52,600
DAVID Malan: Muda.

761

Ni rahisi sana kwa
aina 12345 na mimi nina sasa

762
00:34:54,516 --> 00:34:57,670
katika dhidi kitu ambacho ni 24
wahusika kwa muda mrefu au aya fupi.

763
00:34:57,670 --> 00:34:58,170
Nini kingine?

00:35:01,702 --> 00:35:03,660
Hivyo wewe ni aina ya kubadilisha
tishio mazingira.

767
00:35:03,660 --> 00:35:07,110
Kama mtu guesses au takwimu
nje au anasoma baada ya hayo kumbuka

768
00:35:07,110 --> 00:35:09,900
katika faili yako kuba salama,
bwana password una,

769
00:35:09,900 --> 00:35:12,576
sasa kila kitu ni kuathirika
ambapo awali ni

770
00:35:12,576 --> 00:35:13,700
Ilikuwa labda akaunti moja tu.

771
00:35:13,700 --> 00:35:14,200
Nini kingine?

772
00:35:14,200 --> 00:35:16,640
>> Watazamaji: Kama unataka kutumia yoyote
ya akaunti yako kwenye kifaa kingine

773
00:35:16,640 --> 00:35:18,110
na huna LastPass [inaudible].

774
00:35:18,110 --> 00:35:19,680
>> DAVID Malan: Yeah, hiyo ni
aina ya kukamata, pia.

775
00:35:19,680 --> 00:35:22,080
Pamoja na zana hizo, pia, kama
huna kompyuta yako

776
00:35:22,080 --> 00:35:25,430
na uko katika, kama, baadhi cafe au uko
katika nyumba ya rafiki au maabara ya kompyuta

777
00:35:25,430 --> 00:35:27,750
au popote unataka na
kuingia katika Facebook,

778
00:35:27,750 --> 00:35:29,980
huna hata kujua nini
yako Facebook password ni.

779
00:35:29,980 --> 00:35:32,600
Sasa wakati mwingine, unaweza kupunguza
hivyo kwa kuwa suluhisho

780
00:35:32,600 --> 00:35:35,670
kwamba tutaweza majadiliano juu katika muda tu
aitwaye mbili sababu uthibitisho

781
00:35:35,670 --> 00:35:38,740
ambapo Facebook Nakala wewe au
kutuma ujumbe maalum encrypted

782
00:35:38,740 --> 00:35:41,120
kwa simu yako au nyingine
kifaa kwamba wewe kubeba kuzunguka

783
00:35:41,120 --> 00:35:42,912
juu ya keychain yako na
ambayo unaweza kuingia katika.

784
00:35:42,912 --> 00:35:46,120
Lakini hiyo ni, pengine, annoying kama wewe ni
katika basement ya kituo cha sayansi

785
00:35:46,120 --> 00:35:48,130
au mahali pengine hapa katika chuo New Haven ya.

786
00:35:48,130 --> 00:35:49,320
Unaweza kuwa ishara.

787
00:35:49,320 --> 00:35:51,044
Na hivyo ndiyo si lazima ufumbuzi.

788
00:35:51,044 --> 00:35:52,210
Hivyo ni kweli ni biashara-off.

789
00:35:52,210 --> 00:35:54,780
Lakini nini napenda kuhimiza wewe
do-- kama wewe kwenda kwenye tovuti CS50,

790
00:35:54,780 --> 00:35:57,750
sisi kweli kupangwa kwa kwanza ya
makampuni haya kwa tovuti leseni,

791
00:35:57,750 --> 00:36:00,541
hivyo kusema, kwa wanafunzi wote CS50
hivyo huna kulipa $ 30

792
00:36:00,541 --> 00:36:01,860
au hivyo kawaida gharama.

793
00:36:01,860 --> 00:36:06,030
Kwa Macs na Windows, unaweza kuangalia nje
1Password kwa ajili ya bure kwenye tovuti CS50,

794
00:36:06,030 --> 00:36:07,730
na tutaweza ndoano ninyi mahakamani na kwamba.

795
00:36:07,730 --> 00:36:10,630
>> Kutambua, pia kwamba baadhi ya
tools-- hizi ikiwa ni pamoja na LastPass

796
00:36:10,630 --> 00:36:13,280
katika moja ya forms-- wake ni
wingu makao, kama Colbert

797
00:36:13,280 --> 00:36:17,584
anasema, ambayo ina maana nywila yako
ni encryptedly kuhifadhiwa katika wingu.

798
00:36:17,584 --> 00:36:20,750
Wazo kuna kuwa unaweza kwenda kwa
baadhi mtu random au kompyuta ya rafiki

799
00:36:20,750 --> 00:36:23,030
na kuingia kwenye Facebook yako
akaunti au kama

800
00:36:23,030 --> 00:36:26,287
kwa sababu wewe kwanza kwenda
lastpass.com, kupata password yako,

801
00:36:26,287 --> 00:36:27,120
na basi aina yake katika.

802
00:36:27,120 --> 00:36:29,180
Lakini nini tishio mazingira huko?

803
00:36:29,180 --> 00:36:31,610
Kama wewe ni hifadhi mambo
katika wingu, na uko

804
00:36:31,610 --> 00:36:35,980
kupata tovuti kwamba
juu ya baadhi ya kompyuta wasiojulikana,

805
00:36:35,980 --> 00:36:40,561
nini inaweza rafiki yako kufanya
na wewe au kwa keystrokes yako?

806
00:36:40,561 --> 00:36:41,060
SAWA.

807
00:36:41,060 --> 00:36:44,140
Mimi itakuwa manually kuendeleza
slides hapa juu ya nje.

808
00:36:44,140 --> 00:36:45,020
>> Keylogger, sawa?

809
00:36:45,020 --> 00:36:47,030
Aina nyingine ya zisizo
ni keylogger, ambayo

810
00:36:47,030 --> 00:36:49,740
ni tu mpango kwamba kweli
magogo kila kitu wewe aina.

811
00:36:49,740 --> 00:36:53,580
Kwa hiyo, kuna, pia, pengine ni bora
kuwa na baadhi ya kifaa sekondari kama hii.

812
00:36:53,580 --> 00:36:55,320
>> Kwa hiyo kile ni mbili sababu uthibitisho?

813
00:36:55,320 --> 00:36:58,240
Kama jina la kupendekeza, ni una
si moja lakini mambo mawili ambayo

814
00:36:58,240 --> 00:36:59,870
kuthibitisha na tovuti.

815
00:36:59,870 --> 00:37:04,520
Hivyo badala ya kutumia tu neno la siri,
una baadhi ya wengine Sababu ya pili.

816
00:37:04,520 --> 00:37:07,479
Sasa, kwamba kwa ujumla ni, moja,
sababu ni kitu unajua.

817
00:37:07,479 --> 00:37:09,520
Hivyo kitu aina ya katika
macho ya akili yako, ambayo ni

818
00:37:09,520 --> 00:37:11,160
password yako ambayo umefanya kujikumbusha.

819
00:37:11,160 --> 00:37:13,870
Lakini wawili, si kitu kingine
kwamba unajua au kujikumbusha

820
00:37:13,870 --> 00:37:15,690
lakini kitu kimwili na.

821
00:37:15,690 --> 00:37:18,607
Wazo hapa akiwa
tishio yako tena

822
00:37:18,607 --> 00:37:20,940
inaweza kuwa baadhi mtu random
kwenye mtandao ambao wanaweza tu

823
00:37:20,940 --> 00:37:22,400
nadhani au kufikiri password yako nje.

824
00:37:22,400 --> 00:37:25,779
Yeye au yeye ana kuwa na kimwili
upatikanaji wa kitu ambacho una,

825
00:37:25,779 --> 00:37:27,570
ambayo bado inawezekana
na bado, labda,

826
00:37:27,570 --> 00:37:29,150
wote zaidi kimwili kutisha.

827
00:37:29,150 --> 00:37:31,024
Lakini ni angalau
aina mbalimbali za tishio.

828
00:37:31,024 --> 00:37:34,360
Siyo watu milioni Nameless
huko nje kujaribu kupata katika data zako.

829
00:37:34,360 --> 00:37:36,730
Sasa ni maalum sana
mtu, pengine,

830
00:37:36,730 --> 00:37:40,370
kwamba kama hiyo ni suala hilo, hiyo ni
Tatizo jingine kabisa, kama vile.

831
00:37:40,370 --> 00:37:42,670
>> Hivyo kwamba kwa ujumla ipo
kwa simu za au vifaa vingine.

832
00:37:42,670 --> 00:37:46,540
Na, kwa kweli, Yale tu limekwisha
hii nje katikati ya muhula kama

833
00:37:46,540 --> 00:37:48,456
kwamba hii haina kuathiri
folks katika chumba hiki.

834
00:37:48,456 --> 00:37:50,330
Lakini wale zifuatazo
pamoja katika New Haven

835
00:37:50,330 --> 00:37:52,410
kujua kwamba kama wewe d kuingia
ndani ya yale.net ID yako,

836
00:37:52,410 --> 00:37:54,720
pamoja na kuandika yako
user jina na password yako,

837
00:37:54,720 --> 00:37:56,060
wewe ni kisha ilisababisha na hii.

838
00:37:56,060 --> 00:37:58,060
Na, kwa mfano, hii ni
Je, ungependa mimi alichukua leo asubuhi

839
00:37:58,060 --> 00:37:59,640
wakati mimi watumiaji katika Yale akaunti yangu.

840
00:37:59,640 --> 00:38:02,480
Na inapeleka mimi sawa
ya ujumbe wa maandishi kwa simu yangu.

841
00:38:02,480 --> 00:38:05,750
Lakini katika hali halisi, mimi kupakuliwa programu
mapema kwamba Yale sasa inasambaza,

842
00:38:05,750 --> 00:38:08,840
na mimi kuwa na sasa aina tu katika
kificho kwamba wao kutuma kwa simu yangu.

843
00:38:08,840 --> 00:38:11,830
>> Lakini kwa kuwa wazi,
suala la mafanikio ya hii ni kwamba sasa,

844
00:38:11,830 --> 00:38:14,550
hata kama mtu takwimu za nje
Yale nenosiri langu, mimi nina salama.

845
00:38:14,550 --> 00:38:15,300
Hiyo haitoshi.

846
00:38:15,300 --> 00:38:18,990
Hiyo ni muhimu moja tu, lakini mimi
haja mbili ya kufungua akaunti yangu.

847
00:38:18,990 --> 00:38:21,886
Lakini nini upande wa chini,
pengine, kwa mfumo wa Yale Mungu?

848
00:38:21,886 --> 00:38:24,420
Na tutaweza basi Yale kujua.

849
00:38:24,420 --> 00:38:26,770
Nini upande wa chini?

850
00:38:26,770 --> 00:38:28,369
Nini hiyo?

851
00:38:28,369 --> 00:38:31,660
Kama huna kiini huduma au kama wewe
hawana huduma Wi-Fi kwa sababu wewe ni

852
00:38:31,660 --> 00:38:34,760
tu katika basement au kitu, wewe
wanaweza kuwa na uwezo wa kupata ujumbe.

853
00:38:34,760 --> 00:38:37,640
Shukrani nyingi, katika kesi hii,
hii itatumia Wi-Fi au kitu kingine,

854
00:38:37,640 --> 00:38:38,730
ambayo inafanya kazi ya kuzunguka.

855
00:38:38,730 --> 00:38:39,730
Lakini mazingira iwezekanavyo.

856
00:38:39,730 --> 00:38:41,067
Nini kingine?

857
00:38:41,067 --> 00:38:42,150
Unaweza kupoteza simu yako.

858
00:38:42,150 --> 00:38:43,108
Wewe tu hawana yake.

859
00:38:43,108 --> 00:38:43,964
Betri akifa.

860
00:38:43,964 --> 00:38:45,880
I mean, kuna idadi
matukio ya annoying

861
00:38:45,880 --> 00:38:50,040
lakini matukio iwezekanavyo ambayo inaweza kutokea
kwamba kukufanya majuto uamuzi huu.

862
00:38:50,040 --> 00:38:52,450
Na mbaya zaidi kutokea
matokeo, kusema ukweli, kisha

863
00:38:52,450 --> 00:38:54,979
itakuwa kwa watumiaji wa
afya huu kabisa.

864
00:38:54,979 --> 00:38:56,770
Hivyo kuna kila mara kwenda
kuwa mvutano huu.

865
00:38:56,770 --> 00:38:59,950
Na una kupata kwa mwenyewe
kama mtumiaji aina ya doa tamu.

866
00:38:59,950 --> 00:39:03,110
Na kwa kufanya hivyo, kuchukua wanandoa
ya mapendekezo ya saruji.

867
00:39:03,110 --> 00:39:07,170
Kama matumizi ya Google Gmail au Google Apps,
kujua kwamba kama wewe kwenda URL hii hapa,

868
00:39:07,170 --> 00:39:09,300
unaweza kuwawezesha mbili sababu
uthibitisho.

869
00:39:09,300 --> 00:39:11,807
Google simu yake uthibitisho wa hatua 2.

870
00:39:11,807 --> 00:39:13,890
Na wewe click Setup, na
basi kufanya hasa kwamba.

871
00:39:13,890 --> 00:39:16,960
Kwamba ni jambo jema la kufanya, hasa
siku hizi kwa sababu, kutokana na biskuti,

872
00:39:16,960 --> 00:39:18,510
umeingia katika karibu wote siku kwa muda mrefu.

873
00:39:18,510 --> 00:39:20,910
Hivyo mara chache kuwa na
aina password yako anyway.

874
00:39:20,910 --> 00:39:23,360
Basi unaweza kufanya hivyo mara moja
wiki, mara moja kwa mwezi, mara moja kwa siku,

875
00:39:23,360 --> 00:39:25,650
na ni chini ya kubwa
kukabiliana kuliko ilivyokuwa zamani.

876
00:39:25,650 --> 00:39:27,470
>> Facebook, pia, ina hii.

877
00:39:27,470 --> 00:39:31,710
Kama wewe ni kidogo pia huru na kuandika
yako Facebook nenosiri ndani ya marafiki '

878
00:39:31,710 --> 00:39:35,640
kompyuta, angalau kuwawezesha mbili sababu
uthibitisho ili kwamba rafiki,

879
00:39:35,640 --> 00:39:39,940
hata kama yeye au yeye ana
logger keystroke,

880
00:39:39,940 --> 00:39:41,440
hawawezi kupata katika akaunti yako.

881
00:39:41,440 --> 00:39:43,100
Naam, kwa nini ni kwamba?

882
00:39:43,100 --> 00:39:45,810
Hakuweza wao tu kuingia
kificho nimekuwa typed katika kwenye simu yangu

883
00:39:45,810 --> 00:39:47,647
kwamba Facebook ametuma kwangu?

884
00:39:47,647 --> 00:39:48,563
Watazamaji: [inaudible].

885
00:39:48,563 --> 00:39:50,990

886
00:39:50,990 --> 00:39:51,740
DAVID Malan: Yeah.

887
00:39:51,740 --> 00:39:53,890
Programu vizuri iliyoundwa
kutakuwa na mabadiliko codes wale

888
00:39:53,890 --> 00:39:56,760
waliotumwa kwa simu yako
kila baada ya sekunde chache au kila wakati

889
00:39:56,760 --> 00:39:58,790
na ili, ndiyo, hata
kama yeye au yeye takwimu za nje

890
00:39:58,790 --> 00:40:02,032
nini kanuni yako ni, bado uko
salama kwa sababu itakuwa umekwisha.

891
00:40:02,032 --> 00:40:04,240
Na hii ni nini inaonekana
kama kwenye tovuti ya Facebook.

892
00:40:04,240 --> 00:40:06,340
>> Lakini kuna njia nyingine kabisa.

893
00:40:06,340 --> 00:40:10,130
Hivyo kama wale aina ya biashara awamu ya pili
si hasa alluring,

894
00:40:10,130 --> 00:40:13,620
kanuni ya jumla katika usalama ingekuwa
kuwa, vizuri, tu angalau ukaguzi mambo.

895
00:40:13,620 --> 00:40:17,380
Je, si aina ya kuweka kichwa yako katika
mchanga na kamwe tu kujua kama au wakati

896
00:40:17,380 --> 00:40:18,890
tumekuwa kuathirika au kushambuliwa.

897
00:40:18,890 --> 00:40:22,435
Angalau kuanzisha baadhi utaratibu
kwamba taarifa yenu papo hapo

898
00:40:22,435 --> 00:40:25,060
kama kitu ajabu kimetokea
hivyo kwamba angalau nyembamba

899
00:40:25,060 --> 00:40:28,030
dirisha la muda wakati
ambayo mtu anaweza kufanya uharibifu.

900
00:40:28,030 --> 00:40:31,070
>> Na katika hili, I mean following--
katika Facebook, kwa mfano,

901
00:40:31,070 --> 00:40:33,370
unaweza kurejea kwenye kile
watataka tahadhari kuingia.

902
00:40:33,370 --> 00:40:37,020
Na hivi sasa, nimekuwa kuwezeshwa barua pepe
kuingia tahadhari lakini si kuarifiwa.

903
00:40:37,020 --> 00:40:39,290
Na nini maana ni
kwamba kama lugha matangazo

904
00:40:39,290 --> 00:40:41,994
Nimekuwa watumiaji katika computer-- mpya
kama sina cookie,

905
00:40:41,994 --> 00:40:44,660
ni anwani ya IP tofauti, ni
aina mbalimbali za computer--

906
00:40:44,660 --> 00:40:47,580
wao, katika hali hii, kutuma
barua pepe yangu na kumwambia, hey, Daudi.

907
00:40:47,580 --> 00:40:51,200
Inaonekana kama wewe watumiaji katika kutoka
usio wa kawaida kompyuta, tu FYI.

908
00:40:51,200 --> 00:40:54,020
>> Na sasa akaunti langu liwe
kuathirika, au rafiki yangu annoying

909
00:40:54,020 --> 00:40:58,390
anaweza kuwa magogo katika
akaunti yangu sasa posting mambo

910
00:40:58,390 --> 00:41:00,070
juu ya kulisha habari zangu au kama.

911
00:41:00,070 --> 00:41:03,340
Lakini angalau kiasi cha muda
na ambayo mimi ni wajinga wa kwamba

912
00:41:03,340 --> 00:41:04,630
ni super, super nyembamba.

913
00:41:04,630 --> 00:41:06,140
Na siwezi hopefully kujibu.

914
00:41:06,140 --> 00:41:08,974
Hivyo wote watatu wa haya, napenda
kusema, ni mambo mazuri sana kufanya.

915
00:41:08,974 --> 00:41:10,890
Ni baadhi ya vitisho nini
ambazo ni vigumu kidogo

916
00:41:10,890 --> 00:41:13,060
kwa ajili yetu watumiaji na kulinda dhidi ya mwisho?

917
00:41:13,060 --> 00:41:16,180
Je, mtu yeyote kujua nini
kikao cha utekaji nyara ni?

918
00:41:16,180 --> 00:41:18,800
Ni tishio zaidi ya kiufundi,
lakini ukoo sana sasa kwamba tumekuwa

919
00:41:18,800 --> 00:41:22,450
amefanya pset sita na saba na sasa nane.

920
00:41:22,450 --> 00:41:27,260
Hivyo kukumbuka kwamba wakati kutuma trafiki
juu ya mtandao, mambo kadhaa kutokea.

921
00:41:27,260 --> 00:41:32,450
Hebu kwenda mbele na
kuingia katika C9 au CS50.io.

922
00:41:32,450 --> 00:41:36,240
Nipe muda tu moja kwa
kuingia katika akaunti yangu jharvard.

923
00:41:36,240 --> 00:41:37,590
>> Watazamaji: Nini password yako.

924
00:41:37,590 --> 00:41:40,530
>> DAVID Malan: 12345.

925
00:41:40,530 --> 00:41:41,740
Sawa.

926
00:41:41,740 --> 00:41:45,530
Na katika hapa, tunajua kwamba kama mimi kwenda
mbele na kuomba mtandao page--

927
00:41:45,530 --> 00:41:47,030
na wakati huo huo, napenda kufanya hivyo.

928
00:41:47,030 --> 00:41:50,390
Hebu kufungua Chrome ya Inspekta
tabo na mtandao wangu trafiki.

929
00:41:50,390 --> 00:41:57,120
Na napenda kwenda kwa
http://facebook.com na ya wazi hii.

930
00:41:57,120 --> 00:41:58,120
Kwa kweli, unajua nini?

931
00:41:58,120 --> 00:42:04,800
Hebu kwenda zaidi ya ukoo
one-- https://finance.cs50.net

932
00:42:04,800 --> 00:42:08,300
na bonyeza Enter na kuingia
mtandao wa trafiki hapa.

933
00:42:08,300 --> 00:42:13,930
>> Hivyo taarifa hapa, kama mimi kuangalia
katika mtandao wangu trafiki,

934
00:42:13,930 --> 00:42:17,140
majibu headers-- hebu kwenda juu hapa.

935
00:42:17,140 --> 00:42:18,920
Response headers-- hapa.

936
00:42:18,920 --> 00:42:23,740
Hivyo ombi la kwanza kabisa kwamba mimi
akatuma watu, ambayo ilikuwa kwa ukurasa msingi,

937
00:42:23,740 --> 00:42:25,800
ni alijibu kwa
majibu headers haya.

938
00:42:25,800 --> 00:42:27,820
Na tumekuwa aliyesema kuhusu
mambo kama eneo.

939
00:42:27,820 --> 00:42:30,700
Kama, eneo ina maana
kuelekeza kwa login.php.

940
00:42:30,700 --> 00:42:33,970
Lakini jambo moja hatukuwa kuzungumza mkubwa
Kiasi kuhusu alikuwa mistari kama hii.

941
00:42:33,970 --> 00:42:36,010
Hivyo hii ni ndani ya
virtual bahasha hiyo ni

942
00:42:36,010 --> 00:42:38,220
ametumwa kutoka CS50 Finance--
toleo la nyie aliandika,

943
00:42:38,220 --> 00:42:41,342
too-- kwa mtumiaji mbali
au kompyuta desktop.

944
00:42:41,342 --> 00:42:42,550
Na hii ni kuweka kuki.

945
00:42:42,550 --> 00:42:44,550
Lakini ni nini kuki?

946
00:42:44,550 --> 00:42:46,110
Fikiria nyuma mjadala wetu wa PHP.

947
00:42:46,110 --> 00:42:48,347
Yeah?

948
00:42:48,347 --> 00:42:51,180
Yeah, ni njia ya kuwaambia
tovuti ya kwamba bado uko watumiaji katika.

949
00:42:51,180 --> 00:42:52,340
Lakini jinsi gani kwamba kazi?

950
00:42:52,340 --> 00:42:57,090
Naam, juu ya kutembelea finance.cs50.net,
inaonekana kama kwamba server

951
00:42:57,090 --> 00:42:59,010
kwamba sisi kutekelezwa ni kuweka kuki.

952
00:42:59,010 --> 00:43:03,280
Na kwamba Kuki ni conventionally
piga PHPSESSID kikao ID.

953
00:43:03,280 --> 00:43:06,305
Na unaweza kufikiria ni kama
virtual handstamp katika klabu au, kama,

954
00:43:06,305 --> 00:43:09,140
Hifadhi ya pumbao, kipande kidogo
nyekundu wino kwamba unaendelea mkono wako

955
00:43:09,140 --> 00:43:12,280
hivyo kwamba wakati mwingine wewe kutembelea
lango, wewe tu kuonyesha mkono wako,

956
00:43:12,280 --> 00:43:16,320
na bouncer mlangoni basi wewe
kupita au si wakati wote kwa kuzingatia kwamba stempu.

957
00:43:16,320 --> 00:43:19,120
>> Hivyo baadae
maombi kwamba browser yangu

958
00:43:19,120 --> 00:43:22,800
sends-- kama mimi kwenda kwa ombi ijayo
na ukiangalia headers ombi,

959
00:43:22,800 --> 00:43:24,450
utasikia taarifa mambo zaidi.

960
00:43:24,450 --> 00:43:26,890
Lakini muhimu zaidi ni hii
sehemu yalionyesha here--

961
00:43:26,890 --> 00:43:28,660
si kuweka kuki lakini kuki.

962
00:43:28,660 --> 00:43:32,090
Na kama mimi flip kupitia kila moja
wale maombi HTTP baadae,

963
00:43:32,090 --> 00:43:35,360
kila wakati napenda kuona mkono
kuwa hadi kwa kuwa exact

964
00:43:35,360 --> 00:43:38,410
PHPSESSID, ambayo ni kusema
hii ni mechanism--

965
00:43:38,410 --> 00:43:41,640
pseudorandom hii kubwa number-- kwamba
server anatumia kudumisha udanganyifu

966
00:43:41,640 --> 00:43:46,390
ya PHP ya $ _SESSION kitu, ambamo
unaweza kuhifadhi vitu kama mtumiaji ID

967
00:43:46,390 --> 00:43:49,720
au nini katika ununuzi gari yao au
idadi yoyote ya vipande nyingine ya data.

968
00:43:49,720 --> 00:43:51,510
>> Hivyo nini maana?

969
00:43:51,510 --> 00:43:54,841
Naam, nini kama kwamba
data haujasimbwa?

970
00:43:54,841 --> 00:43:57,090
Na, kwa kweli, sisi kwa bora
mazoezi encrypt pretty much

971
00:43:57,090 --> 00:43:59,117
kila moja ya tovuti CS50 siku hizi.

972
00:43:59,117 --> 00:44:01,200
Lakini ni kawaida sana hawa
siku kwa ajili ya Nje bado

973
00:44:01,200 --> 00:44:04,640
kutokuwa na HTTPS katika
mwanzo wa URL.

974
00:44:04,640 --> 00:44:06,722
Wao ni tu HTTP, matumbo, kufyeka kufyeka.

975
00:44:06,722 --> 00:44:08,640
Hivyo nini maana huko?

976
00:44:08,640 --> 00:44:10,530
Hiyo ina maana kwamba
wote wa vichwa hizi

977
00:44:10,530 --> 00:44:12,030
ni ndani ya kwamba bahasha virtual.

978
00:44:12,030 --> 00:44:14,860
Na mtu yeyote ambaye sniffs
hewa au kimwili

979
00:44:14,860 --> 00:44:17,660
intercepts kwamba pakiti kimwili
wanaweza kuangalia ndani na kuona

980
00:44:17,660 --> 00:44:18,590
nini kwamba Kuki ni.

981
00:44:18,590 --> 00:44:21,700
>> Na hivyo kikao cha utekaji nyara
ni tu mbinu

982
00:44:21,700 --> 00:44:25,590
kwamba adui anatumia vuta data
katika hewa au kwenye baadhi mtandao wired,

983
00:44:25,590 --> 00:44:27,340
kuangalia ndani ya hii
bahasha, na kuona, loo.

984
00:44:27,340 --> 00:44:30,450
Mimi naona kwamba cookie yako
ni 2kleu chochote.

985
00:44:30,450 --> 00:44:33,390
Hebu kwenda mbele na kufanya
nakala ya mkono wako wa stempu

986
00:44:33,390 --> 00:44:37,050
na sasa kuanza kutembelea Picha
au Gmail au chochote mimi mwenyewe

987
00:44:37,050 --> 00:44:39,360
na tu sasa
exact handstamp.

988
00:44:39,360 --> 00:44:42,510
Na ukweli ni, browsers na
watumishi kweli ni kwamba wasiojua.

989
00:44:42,510 --> 00:44:45,780
Kama server anaona kuwa sawa
cookie, madhumuni yake katika maisha

990
00:44:45,780 --> 00:44:47,660
lazima kusema, loo,
kwamba lazima Daudi,

991
00:44:47,660 --> 00:44:49,570
ambao tu watumiaji katika kidogo iliyopita.

992
00:44:49,570 --> 00:44:53,860
Napenda kuonyesha mtumiaji huyu huo,
labda, Inbox Daudi au Facebook

993
00:44:53,860 --> 00:44:56,260
ujumbe au kitu kingine chochote
ndani ambayo yako sasa.

994
00:44:56,260 --> 00:44:58,950
>> Na upande wa utetezi tu dhidi ya
kuwa ni encrypt tu

995
00:44:58,950 --> 00:45:00,760
kila kitu ndani ya bahasha.

996
00:45:00,760 --> 00:45:03,200
Na nashiriki, mengi ya maeneo kama
Facebook na Google na kama

997
00:45:03,200 --> 00:45:04,200
wanafanya hivyo siku hizi.

998
00:45:04,200 --> 00:45:07,159
Lakini yoyote ambayo si kuondoka wewe
kikamilifu, kikamilifu katika mazingira magumu.

999
00:45:07,159 --> 00:45:10,200
Na moja ya mambo unaweza do--
na moja ya sifa nzuri, kusema ukweli,

1000
00:45:10,200 --> 00:45:12,180
ya 1Password, programu
Nilivyoeleza awali,

1001
00:45:12,180 --> 00:45:14,682
ni kama wewe kufunga hiyo kwenye yako
Mac au PC, programu,

1002
00:45:14,682 --> 00:45:16,390
badala ya kuhifadhi yako
nywila, mapenzi pia

1003
00:45:16,390 --> 00:45:20,840
kuonya kama wewe milele kujaribu
magogo katika tovuti hiyo ni

1004
00:45:20,840 --> 00:45:23,065
kwenda kupeleka jina lako
na neno la siri kimaandishi

1005
00:45:23,065 --> 00:45:25,740
na katika wazi, hivyo kusema.

1006
00:45:25,740 --> 00:45:26,240
Sawa.

1007
00:45:26,240 --> 00:45:28,120
Hivyo kikao cha utekaji nyara majipu chini kwamba.

1008
00:45:28,120 --> 00:45:31,950
Lakini kuna hii nyingine
njia hiyo HTTP headers

1009
00:45:31,950 --> 00:45:34,950
inaweza kutumika kwa kuchukua faida ya sisi.

1010
00:45:34,950 --> 00:45:36,530
Na hii ni bado aina ya suala hilo.

1011
00:45:36,530 --> 00:45:39,405
Hii ni kweli tu adorable
udhuru kuweka Cookie Monster hapa.

1012
00:45:39,405 --> 00:45:42,360
Lakini Verizon na AT & T na
wengine alichukua mengi ya flak

1013
00:45:42,360 --> 00:45:46,510
miezi michache nyuma kwa sindano,
unbeknownst kwa watumiaji awali,

1014
00:45:46,510 --> 00:45:48,640
HTTP ziada kichwa.

1015
00:45:48,640 --> 00:45:52,680
>> Hivyo wale ambao wamekuwa na
Verizon Wireless au AT & T kiini

1016
00:45:52,680 --> 00:45:56,280
za, na tumekuwa kutembelea
tovuti kupitia simu yako,

1017
00:45:56,280 --> 00:46:00,510
unbeknownst wewe, baada ya HTTP yako
maombi kuondoka Chrome au Safari

1018
00:46:00,510 --> 00:46:04,620
au chochote kwenye simu yako, nenda
kwa Verizon au AT & T ruta,

1019
00:46:04,620 --> 00:46:07,530
wao kujikinai
kwa muda wamekuwa

1020
00:46:07,530 --> 00:46:10,990
sindano kichwa kwamba inaonekana
kama hii jozi ufunguo thamani ambapo

1021
00:46:10,990 --> 00:46:14,300
muhimu ni tu X-UIDH
kwa kitambulisho kipekee

1022
00:46:14,300 --> 00:46:17,110
kichwa na kisha baadhi thamani kubwa bila mpangilio.

1023
00:46:17,110 --> 00:46:18,950
Nao kufanya hivyo hivyo
kuwa wanaweza kipekee

1024
00:46:18,950 --> 00:46:25,050
kutambua yote ya mtandao trafiki yako kwa
watu wanaopata ombi lako HTTP.

1025
00:46:25,050 --> 00:46:27,300
>> Sasa, kwa nini Verizon
na AT & T na kama

1026
00:46:27,300 --> 00:46:30,140
wanataka kipekee kutambua wewe
tovuti wote wewe ni kutembelea?

1027
00:46:30,140 --> 00:46:31,740
>> Watazamaji: huduma bora kwa wateja.

1028
00:46:31,740 --> 00:46:33,510
>> DAVID Malan: Better-- hakuna.

1029
00:46:33,510 --> 00:46:37,430
Ni mawazo mazuri, lakini ni
si kwa huduma bora kwa wateja.

1030
00:46:37,430 --> 00:46:38,970
Nini kingine?

1031
00:46:38,970 --> 00:46:40,140
Matangazo, sawa?

1032
00:46:40,140 --> 00:46:42,970
Ili waweze kujenga
matangazo ya mtandao, labda,

1033
00:46:42,970 --> 00:46:45,570
ambapo hata kama wewe
kuwa akageuka mbali biskuti,

1034
00:46:45,570 --> 00:46:48,090
hata kama una maalum
programu kwenye simu yako

1035
00:46:48,090 --> 00:46:50,970
kwamba anaendelea wewe katika fiche mode-- ha.

1036
00:46:50,970 --> 00:46:54,195
Hakuna hali fiche wakati
Mtu katika middle-- halisi, Verizon

1037
00:46:54,195 --> 00:46:57,410
au AT & T-- ni kuingiza
data ya ziada ambalo

1038
00:46:57,410 --> 00:47:02,450
wewe huna udhibiti, na hivyo akifafanua
wewe ni kwa kuwa tovuti kusababisha ambao

1039
00:47:02,450 --> 00:47:03,280
tena na tena.

1040
00:47:03,280 --> 00:47:06,720
>> Hivyo kuna njia ya kuchagua nje ya hii.

1041
00:47:06,720 --> 00:47:08,970
Lakini hapa, pia, ni kitu
kwamba kusema ukweli, njia pekee

1042
00:47:08,970 --> 00:47:12,070
kushinikiza nyuma juu ya hii ni kuondoka
carrier kabisa, afya yake

1043
00:47:12,070 --> 00:47:14,610
kama hata kuruhusu,
au, kama ilivyotokea katika kesi hiyo,

1044
00:47:14,610 --> 00:47:18,910
kufanya kidogo kabisa ya fuss online kama
kwamba makampuni kweli kujibu.

1045
00:47:18,910 --> 00:47:22,640
Hii pia, ni tu mwingine
nafasi adorable kuonyesha hili.

1046
00:47:22,640 --> 00:47:30,530
>> Na hebu tuangalie, hebu
kusema, moja au mbili vitisho mwisho.

1047
00:47:30,530 --> 00:47:32,860
Hivyo kuongelea CS50 Fedha hapa.

1048
00:47:32,860 --> 00:47:37,590
Hivyo utasikia taarifa kwamba tuna hii cute
icon kidogo juu ya kuingia kifungo hapa.

1049
00:47:37,590 --> 00:47:40,550
Ina maana gani kama mimi
badala yake kutumia icon hili?

1050
00:47:40,550 --> 00:47:42,240
Hivyo kabla, baada ya.

1051
00:47:42,240 --> 00:47:43,645
Kabla baada.

1052
00:47:43,645 --> 00:47:44,520
Je baada ya maana?

1053
00:47:44,520 --> 00:47:47,470

1054
00:47:47,470 --> 00:47:49,324
Ni salama.

1055
00:47:49,324 --> 00:47:50,740
Hiyo ni nini Ningependa kufikiri.

1056
00:47:50,740 --> 00:47:53,690
Lakini hazijaingizwa, ni salama
kwa sababu hatuwezi kuwa HTTPS.

1057
00:47:53,690 --> 00:47:56,840
>> Lakini hiyo ni jinsi gani ni rahisi kubadili
kitu kwenye tovuti, sawa?

1058
00:47:56,840 --> 00:47:58,555
Wewe wote tunajua kidogo ya HTML na CSS sasa.

1059
00:47:58,555 --> 00:48:00,430
Na kwa kweli, ni pretty
rahisi to-- na kama wewe

1060
00:48:00,430 --> 00:48:01,990
hakufanya it-- kubadili icon.

1061
00:48:01,990 --> 00:48:04,240
Lakini hii, pia, ndivyo
makampuni wamefundisha tufanye.

1062
00:48:04,240 --> 00:48:06,890
Hivyo hapa ni screenshot kutoka Benki
ya tovuti Amerika ya leo asubuhi.

1063
00:48:06,890 --> 00:48:08,973
Na taarifa, moja, wao uko
kumtuliza mimi hiyo ni ni

1064
00:48:08,973 --> 00:48:11,030
ishara salama katika juu ya kushoto.

1065
00:48:11,030 --> 00:48:13,530
Na wao pia wana
kufuli icon kifungo,

1066
00:48:13,530 --> 00:48:16,820
ambayo ina maana gani kwangu, mtumiaji wa mwisho?

1067
00:48:16,820 --> 00:48:18,390
>> Kweli kitu, sawa?

1068
00:48:18,390 --> 00:48:21,070
Je, jambo ni kweli
kwamba kuna kijani kubwa

1069
00:48:21,070 --> 00:48:22,950
URL juu juu na HTTPS.

1070
00:48:22,950 --> 00:48:27,120
Lakini kama sisi kuvuta juu ya hili, ni tu
kama mimi, akijua kidogo ya HTML

1071
00:48:27,120 --> 00:48:30,280
na kidogo ya CSS, na kusema,
