Imininingwane yohlelo lokubhala idatha ye-Zero Data
Izinhlelo eziningi zamafayela we-shredder kanye nedatha yokubhujiswa kwedatha zisekela indlela yokwaziswa kwe-software ye-Write Zero esekelwe ekubhaleni idatha ekhona kudivayisi yokugcina njenge- hard drive .
Indlela yokwenza idatha ye-sanitization ye-Write Zero ingase ingayeki izindlela zokubuyisela ezisekelwe kwi- hardware eziphambili kakhulu kusukela ekukhipha okungenani idatha esusiwe, kodwa kungenzeka ukuthi ivimbele zonke izindlela zokutakula ifayela le-software kusuka ekuphakameni ulwazi kusukela ku-drive.
Qaphela: Ngezinye izikhathi indlela ye-Write Zero, futhi ngokunembile, ibizwa ngokuthi i- Single Overwrite indlela. Kungase futhi kuthiwa i- zero fill fill or fill-zero .
Yini Engayibhala Ngayo?
Ezinye izindlela zokunakekelwa kwedatha, njengeGitmann neDoD 5220.22-M , zizobhala izinhlamvu ezingahleliwe mayelana nolwazi olukhona ku-drive. Kodwa-ke, indlela yokuhlanza idatha ye-Write Zero, engaqiniseki, ngokuvamile isebenza ngendlela elandelayo:
- Dlula 1: Ubhala iZero
Okunye ukuqaliswa kohlelo lwe-Write Zero kungabandakanya ukuqinisekiswa ngemuva kokudlula kokuqala, kungabhala uhlamvu ngaphandle kwezinga, noma kungabhala i-zeros ngaphezu kwamaphesenti amaningi, kodwa lezo azizona izindlela ezivamile zokwenza.
Ithiphu: Iningi lezinhlelo zesofthiwe ezisekela i-Write Zero zinikeza indlela yokwenza umlingiswa ngokwezifiso kanye nenani lezikhathi zokuqinisekisa ukuthi zenzeka. Lokho kusho, shintsha lokho okwanele futhi awusayisebenzisi ngempela i- Write Zero .
Ingabe Ubhalele Okwanele Ukuqeda Idatha?
Kungenzeka ukuthi, yebo. Nokho ...
Ezinye izindlela zokunakekelwa kwedatha zenza idatha yakho evamile, efundekayo nezinhlamvu ezingahleliwe. Njengoba nje kukhulunywe ngenhla, Bhala iZero into efanayo kodwa isebenzisa, kahle ... zeros. Ngomqondo ongokoqobo, uma usula i-hard drive nge-zero bese uyiphonsa, i-diver dumpster yakho engahleliwe oyibamba ngeke akwazi ukuthola noma iyiphi idatha yakho esusiwe.
Uma kuyiqiniso, ungase uzibuze ukuthi kungani ezinye izinhlobo zedatha zisula izindlela ngisho noma zikhona. Ngayo yonke imininingwane yokusula idatha etholakalayo, iyiphi inhloso yensiza yokugcwalisa indawo? Indlela ye- Random Data , isibonelo, ubhala izinhlamvu ezingahleliwe ekushayweni esikhundleni se-zero, ngakho-ke kanjani kuhlukile kunokubhala i-Zero noma enye yabanye?
Esinye isici akusilo nje ukuthi uhlamvu ubhalwe kanjani kodwa indlela ephumelelayo ngayo ekubhaliwe kwedatha. Uma kuphela ukubhalwa kokubhala okukodwa okwenziwe, futhi isofthiwe ayiqinisekisi ukuthi zonke izingxenye zedatha zisusiwe, khona-ke indlela ngeke iphumelele njengezindlela ezenzayo .
Ngamanye amazwi, uma usebenzisa i-Write Zero ngodrayivu owodwa futhi uqinisekisa ukuthi yonke idatha ibhalwe phansi, ungaqiniseka ngokuthi ulwazi alukwazi ukutholakala kunalokho uma idatha efanayo ibhalwe phansi nge-Random Data method kodwa akazange aqinisekise ukuthi umkhakha ngamunye ushintshiwe ngezinhlamvu ezingahleliwe.
Noma kunjalo, abalingiswa abathile bangase banikeze nobumfihlo obungcono kunezinye. Uma uhlelo lokutakula ifayela lwazi ukuthi idatha ibhalwe nge-zeros kuphela, yenza kube lula kakhulu ukuhlunga ukuthi iyiphi idatha ekhona kunalokho uma uhlelo lungazi izinhlamvu ezisetshenzisiwe, njengalabo abasendleleni ye- Schneier .
Esinye isizathu sazo zonke ezinye izindlela zokusula idatha ukuthi ezinye izinhlangano zifuna ukufakazela ukuthi ulwazi lwabo luyasuswa ngendlela ethize okuvimbela ukutakula, ngakho-ke basebenzisa indlela ethile yokunakekelwa kwe-data nemingcele ethile yabo yonke idatha yabo yokusula idatha .
Izinhlelo Zokusekela Ukubhala Zero
Ku- Windows 10 , i- Windows 8 , i- Windows 7 , ne- Windows Vista , umyalo wefomethi othembekile, ngokuzenzakalelayo, isebenzisa indlela yokuhlanjululwa kwe-Write Zero ngesikhathi senqubo yokufometha . Ungasebenzisa lowo myalo kumyalezo wokubhala ukubhala i-zeros kwi-hard drive ngaphandle kokuthi ulande noma iyiphi isofthiwe esengeziwe noma ithuluzi elikhethekile.
Bheka indlela yokusebenzisa i-Format Command yokubhala iZeros ku-Hard Drive ngemininingwane ngalokhu. Akuyona elula njengokuzwakalayo uma uzama ukwenza lokhu ohlelweni lwakho lokuqalisa.
Kukhona nezinhlelo zeqembu lesithathu ezisekela ngokusebenzisa indlela ye-Write Zero yokususa idatha, njengeDBAN , i- HDShredder , i- KillDisk , ne- Macrorit Disk Partition Wiper . Ezinye zalezi zinhlelo zingasetshenziswa ukusula i-hard drive oyisebenzisayo (njenge-C drive) ngokusebenzisa i-disc noma i- flash drive , futhi abanye bagijima ngaphakathi kwesistimu yokusebenza ukusula ezinye izinkomba, njengezinto ezikhishwayo.
Amanye amathuluzi asebenzisa indlela ye-Write Zero yokususa amafayela athile kunokuba konke okufana nezinhlelo ezingenhla. Izibonelo ezimbalwa zamathuluzi afana nalawo afaka i- WipeFile ne- BitKiller .
Iningi lezinhlelo zokubhujiswa kwedatha lisekela izindlela eziningi zokuhlukunyezwa kwedatha ngaphezu kokubhala iZero, ngakho-ke cishe ungakhetha indlela ehlukile, uma unentshisekelo, uma usuvule uhlelo.
