Ungapheli ukuba ngumfana olahlekelwe izinombolo zezigidi zokuphepha komphakathi
Sonke sibone izindaba ezindabeni, lapho othile abe nekhompyutha ephathekayo enezinombolo eziyisigidi zokuphepha kwezenhlalakahle kuyo ezbiwe kuzo. Akekho kithi ofuna ukuba 'lowo mfana', uma umuntu onolwazi olubucayi kwikhompyutha yakhe ekugcineni ezandleni ezingafanele. Uma ungumuntu obenayo i-laptop, kungenzeka ukuthi uzoxoshwa, ulandelwe, noma kokubili.
Uma ngabe umnyango wakho we-IT wezinkampani ohlinzekele i-laptop yakho unomqondo wokuthi ngabe ufake uhlobo oluthile lokubethela i- disk noma ukuphepha kokuphela kwikhompyutha yakho okwakungenza ukuthi idatha ingayifunde ngokuphelele futhi ingenalutho kunoma ubani oyile.
Ingabe uhlelo lwami lokusebenza alubetheli ngokuzenzakalelayo amafayela ami? Impendulo yilezi: mhlawumbe ngaphandle kokuthi uvule izinketho ze-disk encryption njenge-Bitlocker (Windows) noma i-FileVault (Mac). Ukubethela kubonakala kuvaliwe ngokuzenzakalelayo.
Yini ongayenza ukuze uqinisekise ukuthi idatha yakho ivikelwe ekubhekeni amehlo uma kwenzeka i-laptop yakho ishiwe?
Ake sibheke ezinye izinketho zokubethela i-disk.
I-TrueCrypt (ayisasekelwa - bheka isibuyekezo ngezansi):
Omunye wemikhiqizo ye-disk encryption ye-disk yokukhiya yonke imithombo evulekile yamahhala ekhona evulekile i-TrueCrypt. I-TrueCrypt ye-Windows ikuvumele ukuthi ubhale phansi yonke i-hard drive yakho. Ngokungafani nokubethela kwefayili, ne-disk lonke noma ukubethela kwesistimu, wonke amafayela afaka phakathi amafayela ashintshiwe, amafayela wesikhashana, ukubhalisa kwesistimu, namanye amafayela wesistimu oyinkimbinkimbi abhalwe ngekhodi.
Ngokwesiko, i-hacker izodlula ukuphepha kwefayela lesistimu yokusebenza ngokuthatha i-hard drive ngaphandle kwikhompyutha yesisulu bese uyixhuma kwenye ikhompuyutha njengedrayivu engenakuqhathaniswa. Ikhomputha ye-host that i-hacker ixhuma i-hard drive yesisulu ukuze ikwazi ukufinyelela okuqukethwe kwidrayivu ngoba ayiboshiwe yizici zokuphepha zesistimu yokusebenza kowesisulu. I-hacker isivele ikhululekile ukufinyelela amafayela esiteshini sesisulu njengokungathi yayiyi-drive ye-thumb noma enye i-disk engaxhunyiwe exhunywe kukhompyutha.
I-TrueCrypt ivimbele i-hacker ukuba ikwazi ukubuka okuqukethwe kwedrayivu kanzima ngoba wonke umshini ubhalwe nge-process encryption yonke ye-disk. Uma bezama ukuthola idrayivu kwenye ikhompyutha yabo bonke ababezoyibona ibhalwe nge-cryptographic.
Ngakho i-TrueCrypt iqinisekisa kanjani ukuthi umnikazi wesistimu kuphela othola ukufinyelela kudrayivu? I-TrueCrypt isebenzisa ubuqiniso bokuqala bokuqala okudinga ukuthi umsebenzisi angene iphasiwedi ngaphambi kwenqubo ye-boot ye-Windows.
Ngaphandle kokubethela okuphelele kwe-disk, i-TrueCrypt inikeze ukubethelwa kwamafayili amaningi, ukubethelwa kokuhlukanisa, nokukhethwa kwe-Hidden Volume encryption. Vakashela iwebhusayithi ye-TrueCrypt ukuze uthole imininingwane egcwele.
Ukuvuselelwa: I- TrueCrypt isatholakala (inconyiwe kuphela ngezinhloso zokufuduka kwedatha), kodwa ukuthuthukiswa sekuphelile. Umthuthukisi akabuyekezi isofthiwe isikhathi eside futhi kubonakala kusuka kolwazi kuleli khasi, ukuthi kunezinkinga zokuphepha ezingaxazululwa ezingeke zenziwe manje njengoba ukuthuthuka sekuphelile. Bayaxwayisa ukuthi i-TrueCrypt ayisekho iphephile. Okunye okuyiqiniso kwe-TrueCrypt manje engadingeki kuyoba yi-VeraCrypt.
Ukubhaliwe kokuphela kwe-McAfee
I-TrueCrypt iyindlela enhle kuma-PC, kodwa uma uphatha inombolo enkulu yama-PC adinga ukubethelwa kwe-disk ngokuphelele bese ungase ufune ukuhlola ukubethelwa kwe-Endpoint Ukubethela kwe-McAfee. I-McAfee inikeza ukubethelwa kwe-disk yonke yama-PC ne-Mac okungaphethwe yi-ePolicy Orchestrator (ePO) yesikhulumi.
I-McAfee Endpoint Ukubethela inikeza nekhono lokubethela kalula imidiya ekhishwayo njengamashayela we-USB, ama-DVD, nama-CD.
I-Bitlocker (i-Microsoft Windows) ne-FileVault (i-Mac OS X)
Uma usebenzisa iWindows noma i-Mac OS X, ungakhetha ukusebenzisa isitifiketi sakho se-disk esakhiwe ngokuphelele. Ngenkathi izinketho zokubethela ze-disk ezakhiwe ngaphakathi kwe-OS zikhangayo ngenxa yesici esilula, leli qiniso libuye lenze ukuba kube nemigomo ephezulu kakhulu yabaduni ekufuneni ukukhubazeka. Ukusesha okusheshayo kwewebhu kwembula ingxoxo enkulu ye-Bitlocker ne-FileVault hacks nezihloko ezihlobene.
Kungakhathaliseki ukuthi yikuphi okukhethwa kukho okukhethwa kukho kwe-disk oyikhethayo, kungakhathaliseki ukuthi kusekelwe ngaphakathi ku-OS-based, umthombo ovulekile, noma ukuhweba, qinisekisa ukuthi wonke ama-patches wakho wokuphepha nokusebenza kwesistimu avuselelwa njalo ukuze ukubethelwa kwe-drive yakho kufane ukungabi nengozi-mahhala ngangokunokwenzeka.
