- I-BitLocker isebenzisa ukubethela kwe-AES ukuvikela amadrayivu angaphandle namadivayisi.
- Ihambisana nezinhlelo ze-Pro ne-Enterprise ze Windows futhi idinga TPM.
- Inikeza izindlela ezihlukahlukene zokuqinisekisa kuye ngezidingo zomsebenzisi.
- Isiza ukuthobela imithetho futhi ivikele ekufinyeleleni okungagunyaziwe.
Ukuvikela idatha egcinwe kuma-hard drive nakumadivayisi angaphandle sekuyinto eza kuqala kokubili kumabhizinisi nakubasebenzisi ngabanye. Ngokukhula kwezinsongo zedijithali, ukubethela idatha kuvele njengethuluzi elibalulekile lokuvikela ubumfihlo nokuphepha . Yilapho i-BitLocker ingena khona , ikhambi eliphelele lokubethela amadiski elakhiwe yi -Microsoft futhi lahlanganiswa nezinhlelo zokusebenza ze-Windows iminyaka eminingi.
Kusukela yethulwa ku-Windows Vista, i-BitLocker iqhubekile nokukhula, iziveza njengethuluzi elibalulekile lokuvimbela ukufinyelela okungagunyaziwe, ngisho nasezimweni zokwebiwa noma ukulahleka kwedivayisi. Thola konke okudingeka ukwazi ngalobu buchwepheshe obunamandla ngezansi.
Iyini i-BitLocker futhi ingeyani?
I-BitLocker iyithuluzi lokubethela idiski eligcwele eliklanywe yi-Microsoft ukuvikela idatha egcinwe kuma-hard drive, ama-partition, namadivayisi angaphandle. Isebenzisa ama-algorithms athuthukile njenge- AES (Advanced Encryption Standard) , yenza ulwazi lungafundeki kubantu abangagunyaziwe ngaphandle kokuthi banenkinobho yokucisha ukubethela.
Lo msebenzi uhloselwe kokubili izindawo zasekhaya nezebhizinisi , futhi ungasetshenziswa ukuvikela idatha ebucayi, ukuvimbela ukufinyelela okungafunwa, ngisho nokuqinisekisa ukuthi amadivayisi abiwe noma alahlekile awabeki engcupheni ubumfihlo bomnikazi wawo.
Izidingo zesistimu ukusebenzisa i-BitLocker
Ngaphambi kokusebenzisa i-BitLocker , kubalulekile ukuqinisekisa ukuthi ikhompyutha noma idivayisi yakho ihlangabezana nezidingo ezithile eziyisisekelo . Nakuba ukwenza kusebenze kulula ezinguqulweni ezintsha, izimo zehadiwe nesofthiwe zisadlala indima ebalulekile.
- I-TPM (I-Trusted Platform Module): Kunconywa ukuthi ube ne-TPM 1.2 chip noma ngaphezulu, nakuba ungakhetha iyunithi USB njengenye indlela yokugcina okhiye bokuthola kabusha uma idivayisi ingenayo le mojula.
- Izinhlelo zokusebenza ezisekelwayo: Idrayivu Yobhalomfihlo i Itholakala ezinhlelweni ze-Pro, Enterprise kanye nezeMfundo ze-Windows 7, 8.1, 10 no-11, phakathi kokunye.
- Izingxenye zediski: Uhlelo ludinga okungenani ezimbili ukwahlukaniswa: eyodwa yesistimu yokusebenza kanye neye- ibhuthini, enosayizi omncane ongu-100 MB nefomethi I-NTFS.
- Izilungiselelo zokuqalisa: Kumadivayisi ane-TPM, i-UEFI noma i-BIOS firmware kufanele isekele i-Trusted Computing Group (TCG).
Isebenza kanjani i-BitLocker
Isimiso sokusebenza se- BitLocker silula kodwa siqinile. Isebenzisa i -algorithm yokubethela ye-AES kumodi ye- CBC (Cipher Block Chaining) noma ye -XTS ukuvikela idatha egciniwe. Uma isivuliwe, i-BitLocker ibhala ngemfihlo yonke imininingwane ekudrayivu ekhethiwe, kufaka phakathi amafayela esistimu nabasebenzisi. Bese ikhiya ukufinyelela isebenzisa okhiye bokuthola kabusha noma amaphasiwedi.
Izindlela zokuqinisekisa: I-BitLocker inikeza izinketho ezintathu eziyinhloko zokuphatha ukuphepha kokubethela kwakho:
- Imodi esobala: Isebenzisa imojuli ye-TPM ukuze iqinisekise ubuqotho besistimu yokusebenza ngaphambi kokunikeza ukufinyelela.
- Imodi yokuqinisekisa yomsebenzisi: Idinga amaphasiwedi noma ama-PIN alungiselelwe umnikazi.
- Imodi ye-USB: Ikuvumela ukuthi ugcine ukhiye wokuqalisa kudivayisi ye-USB okufanele ixhunywe lapho isistimu iqala.
Izinzuzo zokusebenzisa i-BitLocker
I-BitLocker inikeza uhla lwezinzuzo eziyenza ibe ithuluzi elibalulekile lokuvikela amadivayisi:
- Ukuvikelwa kwedatha okuthuthukisiwe: Iqinisekisa ukuthi idatha ayifinyeleleki uma kwenzeka kwebiwa noma ukulahleka kwedivayisi.
- Ukuhlanganisa kalula: Ihlanganiswe ngokomdabu ku-Windows, okwenza kube lula ukuyisebenzisa nokuyiphakela.
- Ukuthobela okuvamile: Isiza ukuhambisana nemithethonqubo efana RGPD kanye nezinye izinqubomgomo zokuvikela idatha.
- Ukuvikeleka Okuthuthukisiwe: Isebenzisa okhiye abagcinwe ngokuvikelekile nge-TPM ukuze kuqinisekiswe ubuqotho besistimu ngesikhathi sokuqalisa.
Uyenza isebenze futhi uyilungiselele kanjani i-BitLocker
Ukunika amandla i-BitLocker kumadivayisi e-Windows kuyinqubo elula kakhulu. Nansi indlela yokukwenza isinyathelo ngesinyathelo:
- Finyelela ifayela le- Iphaneli yokulawula bese ukhetha Uhlelo lwezokuphepha.
- Qhafaza Phatha iBitLocker bese ukhetha idrayivu ofuna ukuyibethela.
- Landela imiyalelo yewizadi, ukhetha indlela yokuqinisekisa kanye nendawo ozogcina kuyo ukhiye wokutakula (lokhu kungaba i-akhawunti yakho ye-Microsoft, idrayivu ye-USB, noma ephrintiwe).
- Khetha ukuthi ufuna ukubethela yonke idrayivu noma nje isikhala esisetshenzisiwe.
- Qinisekisa ukubethela bese uqala kabusha ikhompuyutha yakho uma kudingeka.
Imikhawulo nezinyathelo okufanele zicatshangelwe
Naphezu kwezinzuzo zayo, i-BitLocker nayo ayinazo imikhawulo yayo. Isibonelo, ayitholakali ezinhlelweni eziyisisekelo njenge-Windows Home, futhi ukuyisebenzisa ngaphandle kwe-TPM kungadinga ukucushwa okwengeziwe okuyinkimbinkimbi. Ngaphezu kwalokho, ukulahlekelwa ukhiye wokutakula kungasho ukulahlekelwa okuphelele kwedatha ebethelwe.
Kubalulekile ukugcina okhiye ngokuphephile ukuze ugweme izinkinga, kanye nokwenza amakhophi agciniwe edatha ebalulekile njalo .
I-BitLocker yethulwa njengethuluzi elinamandla lokuvikela amadivayisi nedatha ekufinyeleleni okungagunyaziwe. Kungakhathaliseki ukuthi ungumsebenzisi wasekhaya oqaphela ubumfihlo noma ibhizinisi elifuna ukuthobela imithetho, ukusebenzisa lesi sixazululo sokubethela kungenza umehluko omkhulu ekuphepheni kwakho.
