Mu Okutobala 2017, ndinali ndi mwayi wopita ku semina yotsatsira ya DeviceLock DLP system, komwe, kuwonjezera pa ntchito yayikulu yodzitchinjiriza pakutulutsa monga kutseka madoko a USB, kusanthula kwamakalata ndi bolodi, kutetezedwa kwa woyang'anira. kutsatsa. Chitsanzocho ndi chosavuta komanso chokongola - oyika amabwera ku kampani yaying'ono, amaika mapulogalamu, amaika mawu achinsinsi a BIOS, amapanga akaunti ya DeviceLock administrator, ndikusiya ufulu wodzisamalira Windows yokha ndi mapulogalamu ena onse kumaloko. admin. Ngakhale pali cholinga, admin uyu sangabe chilichonse. Koma izi zonse ndi theory ...
Chifukwa pazaka za 20 + za ntchito yopanga zida zotetezera zidziwitso, ndidatsimikiza momveka bwino kuti woyang'anira atha kuchita chilichonse, makamaka ndi mwayi wopezeka pakompyuta, ndiye kuti chitetezo chachikulu chotsutsana nacho chikhoza kukhala miyeso ya bungwe monga kupereka malipoti okhwima komanso chitetezo chakuthupi cha makompyuta omwe ali ndi chidziwitso chofunikira, ndiye nthawi yomweyo Lingaliro lidawuka kuyesa kulimba kwa chinthu chomwe akufuna.
Kuyesera kuchita izi atangotha ββseminayi sikunapambane; chitetezo pakuchotsa ntchito yayikulu DlService.exe idapangidwa ndipo sanaiwale za ufulu wopeza komanso kusankha komaliza kopambana, chifukwa chake iwo anagwa izo, monga ambiri mavairasi, kukana dongosolo mwayi kuwerenga ndi kuchita , Sizinachitike.
Pamafunso onse okhudzana ndi chitetezo cha madalaivala omwe mwina akuphatikizidwa muzogulitsa, woimira wopanga Smart Line adanena molimba mtima kuti "zonse zili pamlingo womwewo."
Patatha tsiku limodzi ndinaganiza zopitiliza kufufuza kwanga ndikutsitsa mtundu woyeserera. Nthawi yomweyo ndinadabwa ndi kukula kwa kugawa, pafupifupi 2 GB! Ndazolowera kuti pulogalamu yamakina, yomwe nthawi zambiri imatchedwa zida zotetezera chidziwitso (ISIS), nthawi zambiri imakhala ndi kukula kocheperako.
Pambuyo kukhazikitsa, ndinadabwa kachiwiri - kukula kwa zomwe tatchulazi ndizokulu kwambiri - 2MB. Nthawi yomweyo ndinaganiza kuti ndi voliyumu yotereyi pali chinachake choti ndigwirepo. Ndinayesa kusintha gawoli pogwiritsa ntchito kujambula mochedwa - idatsekedwa. Ndinafufuza mβmakatalogi a pulogalamuyo, ndipo panali kale madalaivala 13! Ndayang'ana zilolezo - sizinatsekedwe kuti zisinthe! Chabwino, aliyense waletsedwa, tiyeni tichulukitse!
Zotsatira zake zimangosangalatsa - ntchito zonse zimayimitsidwa, ntchitoyo siyiyamba. Kudzitchinjiriza kotani komwe kulipo, tengani ndikutengera chilichonse chomwe mukufuna, ngakhale pama drive flash, ngakhale pamaneti. The drawback yoyamba yaikulu ya dongosolo anatulukira - interconnection wa zigawo zikuluzikulu anali wamphamvu kwambiri. Inde, ntchitoyi iyenera kuyankhulana ndi madalaivala, koma bwanji kuwonongeka ngati palibe amene akuyankha? Chifukwa chake, pali njira imodzi yolambalala chitetezo.
Nditazindikira kuti ntchito yozizwitsayi ndi yofatsa komanso yovuta, ndinaganiza zoyang'ana kudalira kwake pama library a chipani chachitatu. Ndizosavuta kwambiri apa, mndandandawo ndi waukulu, timangochotsa laibulale ya WinSock_II mwachisawawa ndikuwona chithunzi chofananira - ntchitoyo sinayambike, dongosolo latsegulidwa.
Chotsatira chake, tili ndi chinthu chomwecho chomwe wokamba nkhaniyo adalongosola pa seminayi, mpanda wamphamvu, koma osatseka malire onse otetezedwa chifukwa cha kusowa kwa ndalama, ndipo m'dera losavulidwa pali chiuno chokhazikika. Pankhaniyi, poganizira kamangidwe ka mapulogalamu a pulogalamuyo, zomwe sizikutanthauza malo otsekedwa mwachisawawa, koma mapulagi osiyanasiyana, ma interceptors, analyzers a traffic, m'malo mwake ndi mpanda wa picket, wokhala ndi mikwingwirima yambiri. Kunja ndi zomangira zodzigunda komanso zosavuta kumasula. Vuto la mayankho ambiriwa ndikuti ndi kuchuluka kwa mabowo omwe atha kukhalapo, nthawi zonse pamakhala mwayi woyiwala zinazake, kusowa ubale, kapena kusokoneza bata pokwaniritsa chimodzi mwazolowera. Poganizira kuti zofooka zomwe zafotokozedwa m'nkhaniyi zili pamtunda, mankhwalawa ali ndi zina zambiri zomwe zingatenge maola angapo kuti zifufuzidwe.
Kuphatikiza apo, msika uli wodzaza ndi zitsanzo za kukhazikitsidwa koyenera kwa chitetezo chotseka, mwachitsanzo, zinthu zapakhomo zotsutsana ndi ma virus, pomwe kudziteteza sikungangodutsidwa. Monga ndikudziwira, iwo sanali aulesi kwambiri kuti alandire certification ya FSTEC.
Pambuyo pokambirana kangapo ndi antchito a Smart Line, malo angapo ofanana omwe sanamvepo adapezeka. Chitsanzo chimodzi ndi njira ya AppInitDll.
Zingakhale zozama kwambiri, koma nthawi zambiri zimakulolani kuchita popanda kulowa mu OS kernel ndipo osakhudza kukhazikika kwake. Madalaivala a nVidia amagwiritsa ntchito bwino makinawa kuti asinthe adaputala yamavidiyo pamasewera enaake.
Kusowa kwathunthu kwa njira yophatikizira yopangira makina opangira makina ozikidwa pa DL 8.2 kumabweretsa mafunso. Akufuna kufotokozera makasitomala ubwino wa malondawo, fufuzani mphamvu zamakompyuta za ma PC ndi ma seva omwe alipo (zowunikira zochitika ndizofunika kwambiri ndipo ofesi yamakono yamakono makompyuta onse ndi ma nettops a Atom si abwino. munkhaniyi) ndikungotulutsa mankhwalawo pamwamba. Panthawi imodzimodziyo, mawu monga "kuwongolera mwayi" ndi "mapulogalamu otsekedwa" sanatchulidwe nkomwe pa semina. Zinanenedwa za encryption kuti, kuwonjezera pa zovuta, zidzadzutsa mafunso kuchokera kwa olamulira, ngakhale kuti kwenikweni palibe mavuto ndi izo. Mafunso okhudza certification, ngakhale ku FSTEC, amasiyidwa chifukwa chazovuta komanso kutalika kwake. Monga katswiri wodziwa chitetezo chazidziwitso yemwe wakhala akutenga nawo mbali mobwerezabwereza muzochitika zoterezi, ndikhoza kunena kuti pochita izi, zofooka zambiri zofanana ndi zomwe zafotokozedwa m'nkhaniyi zimawululidwa, chifukwa akatswiri a certification laboratories ali ndi maphunziro apadera apadera.
Chotsatira chake, dongosolo la DLP loperekedwa lingathe kuchita ntchito zochepa kwambiri zomwe zimatsimikizira chitetezo cha chidziwitso, pamene zimapanga katundu wochuluka wa makompyuta ndikupanga kumverera kwa chitetezo cha deta yamakampani pakati pa kasamalidwe ka kampani omwe sadziwa zambiri zokhudza chitetezo cha chidziwitso.
Itha kungoteteza zenizeni zenizeni kuchokera kwa ogwiritsa ntchito opanda mwayi, chifukwa ... woyang'anira amatha kuletsa chitetezo chonsecho, ndipo pazinsinsi zazikulu, ngakhale woyang'anira wamkulu woyeretsa amatha kujambula chithunzi pazenera, kapena kukumbukira adilesi kapena nambala ya kirediti kadi poyang'ana pazenera la mnzake. phewa.
Kuphatikiza apo, zonsezi ndizoona pokhapokha ngati sizingatheke kuti ogwira ntchito azitha kulowa mkati mwa PC kapena ku BIOS kuti ayambitse kuyambika kwa media zakunja. Ndiye ngakhale BitLocker, yomwe sizingatheke kuti igwiritsidwe ntchito m'makampani omwe akungoganizira zoteteza zambiri, sizingathandize.
Mapeto ake, monga banal momwe angamvekere, ndi njira yophatikizira yokhudzana ndi chitetezo cha chidziwitso, kuphatikizapo njira zothetsera mapulogalamu / hardware zokha, komanso ndondomeko za bungwe ndi zamakono kuti zithetse kuwombera zithunzi / mavidiyo ndikuletsa "anyamata omwe ali ndi kukumbukira" osaloledwa kulowa. malo. Musamadalire chinthu chozizwitsa cha DL 8.2, chomwe chimalengezedwa ngati njira imodzi yothetsera mavuto ambiri achitetezo chamabizinesi.
