Uhlu lwezindlela zokusungulwa kolwazi lweSofthiwe
Indlela yokuhlanza i-data yindlela ethile lapho uhlelo lokubhujiswa kwedatha noma i- file shredder ibhala phansi idatha ku- hard drive noma kwenye idivayisi yesitoreji.
Izindlela ze-sanitization zedatha nazo zivame ukubhekwa njengezindlela zokususa idatha , izindlela zokusula idatha , ukususa ama-algorithms , kanye nedatha ukusula amazinga .
Iningi lezinhlelo zokubhujiswa kwedatha lisekela izindlela eziningi zokuhlanza idatha.
Qaphela: Ngezinye izindlela , ezinye izindlela zokubhubhisa idatha hhayi ngokusekelwe kwesofthiwe nazo zibizwa ngokuthi izindlela zokuhlanza idatha kodwa isikhathi esiningi leli gama libhekisela kulezi zindlela ezisekelwe kwesofthiwe zokususa idatha.
Uhlu lwezindlela zokunciphisa idatha
Nazi izindlela eziningi ezithandwayo zokunakekelwa kwedatha ezisetshenziselwa izinhlelo zokubhujiswa kwedatha futhi, uma kusebenza, inhlangano noma umuntu ohlonishwayo ovela kulo ndlela:
- Ukuqedwa okuphephile
- I-DoD 5220.22-M (UMnyango Wezokuvikela wase-US)
- I-NCSC-TG-025 (I-US National Security Agency)
- I-AFSSI-5020 (US Air Force)
- AR 380-19 (US Army)
- I-NAVSO P-5239-26 (US Navy)
- I-RCMP i-TSSIT OPS-II (Canada)
- I-CSEC ITSG-06 (Canada)
- I-HMG IS5 (UK)
- I-ISM 6.2.92 (i-Australia)
- I-NZSIT 402 (eNew Zealand)
- I-VSITR (eJalimane)
- I-GOST R 50739-95 (iRussia)
- UGutmann (Peter Gutmann)
- U-Schneier (Bruce Schneier)
- UPfitzner (Roy Pfitzner)
- Idatha engahleliwe
- Bhala iZero
Izinhlelo eziningi zokubhujiswa kwedatha futhi zikuvumela ukuthi wenze ngendlela oyifisayo indlela yakho ye-sanitization yedatha nganoma yikuphi iphethini yokubeka phansi kanye nenani lamaphasi oyifunayo.
Iyiphi indlela yokunakekelwa kwe-data engcono kakhulu?
Ukubhala ngaphezulu noma amafayela amaningi, noma yonke i-hard drive, kanye kanye kanye nomlingisi oyedwa, kufanele avimbele noma iyiphi indlela yokubuyisela ifayela esekelwe kwisofthiwe ekubuyiseleni idatha kusuka ku-hard drive. Lokhu kuvunyelwene ngakho konke emhlabeni jikelele.
Ngokusho kwabanye abacwaningi 1 , ukuchithwa kwedatha okukodwa kukwanele ukuvimbela izindlela ezisekelwe phambili, ezisekelwe kwi-hardware zokukhipha ulwazi kusuka emotweni eyinkimbinkimbi okusho ukuthi izindlela eziningi zokunakekelwa kwedatha zibulala kakhulu. Lokhu akuvunyelwanga ngakho.
Iningi lezazi zivuma ukuthi ukulahla okulondekile kuyindlela engcono kakhulu yokubhala yonke i-hard drive kudlula eyodwa. Indlela elula kakhulu yokubhala iZero ifeza into efanayo, noma ihamba kancane.
Ukusebenzisa indlela yokusula ukusula idatha imane nje kubhala enye idatha ngaphezulu kwedatha yakho yangaphambilini ukuze imininingwane ithathe indawo enye into engenamsebenzi. Idatha entsha i-random futhi ayihambisani nanoma yiluphi ulwazi lwakho lomuntu siqu, yingakho i-ones, zeros, nezinhlamvu ezihleliwe zisetshenziswa.
Uma ukubhalwa okukodwa kunokwanele, kungani kunezindlela eziningi zokuhlanza idatha?
Njengoba ngishilo ngenhla, akubona wonke umuntu ovumelana nesimo se-software esisekelwe sanitization yedatha esizovimbela zonke izindlela ezikhona zokuthola idatha.
Ngenxa yokuthi izindlela eziphambili, ezisekelwe kwi-hardware zokukhipha ulwazi kusuka ezinkampanini ezikhuni zikhona, izinhlangano eziningana zikahulumeni nabacwaningi ziye zazimela ngokuzimela izindlela ezithile zokubhala idatha, ngokusho kocwaningo lwabo, okufanele ivimbele lezi zindlela zokubuyisela ezithuthukile ekusebenzeni.
Kusho ukuthini ku & # 34; Qinisekisa Bhala & # 34 ;?
Uma ufunda kabanzi mayelana nezindlela zokuhlanza idatha yomuntu ngamunye, uzobona ukuthi iningi lazo liqinisekisa ngemva kokubhala umlingiswa phezu kwedatha, okusho ukuthi lihlola i-drive ukuqinisekisa ukuthi okuqukethwe okwamanje kubhalwe phansi.
Ngamanye amazwi, ukuqinisekiswa kokubhala kwedatha kufana nokuthi "ingabe ngenza lokhu ngendlela efanele?" uhlobo lwesheke.
Amanye idatha asula amathuluzi wesofthiwe azokuvumela ukuthi ushintshe inani lezikhathi liqinisekisa ukuthi amafayela aphelile. Abanye bangase baqinisekise kanye kuphela ekupheleni kwenqubo yonke (emva kokuphela kokudlula sekuphelile), kanti abanye bazoqinisekisa ukubhala ngemuva kokudlula konke.
Ukuze uhlole wonke umshini ngemuva kokuthi wonke umuntu adlule ukuze aqinisekise ukuthi amafayela asusiwe ngokuqinisekile azothatha isikhathi esiningi ukuqedela ngoba kufanele ahlolisise kaningi ngaphezu kokuphela kokuphela.
