Uluhlu lweeNkqubo eziSebenzayo zoLondolozo lweSanitization
Indlela yokuhlanjululwa kwedatha yindlela ekhethekileyo apho inkqubo yokubhubhisa idatha okanye ifayile ifakisha idibanisa idatha kwi- hard drive okanye enye ifowuni yokugcina.
Iinkcukacha zendlela yokuhlanjululwa kweenkcukacha nazo zibizwa ngokuba ziindlela zokuchithwa kweedatha, iindlela zokusula idatha , ukusula i-algorithms , kunye nedatha ukusula imigangatho .
Uninzi lweenkqubo zokubhubhisa idatha luxhasa iindlela ezininzi zokucocwa kwedatha.
Qaphela: Ngokwenene, ezinye iindlela zokutshabalalisa iinkcukacha ezingekelwe kwi-software overwriting nazo zibhekiswa njengeendlela zokuhlanjululwa kwedatha kodwa ininzi ixesha elibhekiselele kulezi ndlela zisekhompyutheni zokususa idatha.
Uludwe lweeNkqubo zoLungiso lweNgcaciso
Nazi iindlela ezinokudityaniswa kwedatha zokuncedisa iinkcukacha ezisetyenziselwa iinkqubo zokubhubha kwedatha kwaye, xa kusebenza, umbutho okanye umntu obizwa ngokuba ngumthombo:
- Ukukhuseleka okukhuselekileyo
- I-DoD 5220.22-M (Isebe lezoKhuselo lase-US)
- I-NCSC-TG-025 (i-Arhente kaZwelonke yoKhuseleko lweSizwe)
- AFSSI-5020 (US Air Force)
- AR 380-19 (i-US Army)
- I-NAVSO P-5239-26 (US Navy)
- I-RCMP i-OSS-II (Canada)
- I-CSEC ITSG-06 (Canada)
- HMG IS5 (UK)
- ISM 6.2.92 (Australia)
- I-NZSIT 402 (eNew Zealand)
- VSITR (eJamani)
- IGOST R 50739-95 (iRashiya)
- Gutmann (Peter Gutmann)
- Schneier (Bruce Schneier)
- UPfitzner (uRoy Pfitzner)
- Data Random
- Bhala iZero
Uninzi lweenkqubo zokubhubhisa idatha kwakhona kukuvumela ukuba wenze ngokwezifiso indlela yakho yokuhlanjululwa kwedatha kunye nayiphi na iphethini yokubhaliweyo kunye nenani lezithuba ozifunayo.
Yiyiphi indlela yokuhlanjululwa kwedatha efanelekileyo?
Ukubhalwa kweefayile enye okanye ngaphezulu, okanye yonke i-hard drive, kanye kanye kunye nomlingisi omnye, kufuneka ukhusele nayiphina indlela yokubuyisela ifayile esekelwe kwi-software ukufumana idatha kwi-hard drive. Oku kuthethwe ngokubanzi.
Ngokwabanye abaphandi 1 , ukuchithwa kwesinye kwedatha kwaneleyo ukukhusela ezinye iindlela eziphambili zeekhompyutha, zokukhipha ulwazi kwiimoto ezinzima ezithetha ukuba iindlela ezininzi zokucocwa kwedatha zibulala. Oku akuvunyelwanga ngoku.
Uninzi lweengcali zivuma ukuba i- Erase Erase yindlela efanelekileyo yokubhala ngaphezulu i-hard drive nganye kwisithuba esisodwa. Ilula kakhulu Bhala indlela ye- Zero ifezekisa into efanayo, nangona ihamba kancane.
Ukusebenzisa indlela yokusula ukucima idatha ngokwenene kubhala enye idatha ngaphezu kwedatha yakho yangaphambili ukuze ulwazi lithathe indawo yento engenakuncedo. Idatha emitsha ingundoqo kwaye ayinayo nayiphi na inkcazelo yakho, okokuba kutheni, ii-zeros, kunye neelwimi ezingenanto.
Ukuba enye ibhaliwe yanele, kutheni kukho iindlela ezininzi zokunciphisa idatha?
Njengoko ndikhankanywe ngasentla, akuyiyo yonke into evumayo kwi-software esekelwe kwindlela yokuhlengahlengiswa kwedatha eya kuthintela zonke iindlela ezikhoyo zokubuyisela idatha.
Ngenxa yokuba iiprogram eziphambili, ezisekhompyutheni zenkcazelo yokukhupha ulwazi oluvela kwiimoto ezinzima, iminyango eninzi karhulumente kunye nabaphandi baye bazimela ngokuzimela iindlela ezithile zokubhaliweyo kwedatha, ngokutsho kophando lwabo, kufuneka ithintele le ndlela yokubuyisela phambili ekusebenzeni.
Kuthetha ukuthini ku & # 34; Qinisekisa ukubhala & # 34;
Ukuba ufunda ngokubanzi malunga neendlela zokuhlengahlengiswa kwedatha, uya kubona ukuba uninzi lwabo luqhuba ukuqinisekiswa emva kokubhala umgca phezu kwedatha, oku kuthetha ukuba lihlola i-drive ukuqinisekisa ukuba okubhalwe kuyo kubhalwe phantsi.
Ngamanye amazwi, ukubhalwa kweminatha kubhala ngathi "ngaba ngokwenene ndenza oku okulungileyo?" uhlobo lokukhangela.
Olunye idatha usula amathuluzi esofthiwe uyakuvumela ukuba utshintshe inani lamaxesha liqinisekisa ukuba iifayile ziyahamba. Abanye banokungqinisisa kanye kuphela ekupheleni kwenkqubo yonke (emva kokuba zonke iipasenti zigqityiwe), ngelixa abanye baya kuqinisekisa ukubhalwa emva kokuhamba nganye.
Ukujonga yonke i-drive emva kokuba nganye iphumelele ukuqinisekisa ukuba iifayile ziyacinywa ziya kuthatha ixesha elide ukugqiba kuba kufuneka lihlolisise ngokuphindaphindiweyo kunangoko kuphela ekugqibeleni.
