Iinkcukacha kwi-HMG IS5 Indlela yokuSula idatha
I-HMG IS5 (i-Infosec Standard 5) isetyenzisiwe esekelwe kwisetyenzisi se-sanitization data esetyenziswe kwezinye iifayile zokuqhaqhafaza kunye neenkqubo zokubhubhisa idatha ukuba ibhale ngaphezulu ulwazi olukhoyo kwi- hard drive okanye enye i-device yokugcina.
Ukutshabalalisa i-hard drive usebenzisa indlela ye-HMG IS5 yokuhlanjululwa kwedatha kuya kuthintela zonke iinkqubo zokubuyisela iifayile ezisekelwe kwi-software ukufumana ulwazi kwi-drive kwaye inokuthintela iindlela ezininzi zokubuyisela ezisekhompyutheni ukususela kwiinkcukacha.
Le datha isula indlela eyiyo ivela kwiinguqu ezimbini ezifanayo - i-HMG IS5 Isiseko kunye ne-HMG IS5 Enhancedisiweyo . Ndichaza ukungafani kwazo ngezantsi, kunye nezinye iinkqubo ezisetyenziselwa le ndlela yokuhlanza i-data.
Yintoni i-HMG IS5 yokusula indlela?
Ezinye iinkcukacha zisula iindlela kuphela ubhale i-zero phezu kwedatha, njenge- Bhala Zero . Abanye bafana neDatha yeDatha kuphela basebenzisa izilwanyana ezingenanto. Nangona kunjalo, i-HMG IS5 iyahluke kakhulu kuba iyadibanisa ezimbini.
I-HMG IS5 Inkqubo yesiseko sokunyuselwa kwindlela yokucoca i-sanitization ivame ukuphunyezwa ngendlela elandelayo:
- Ukupasa 1: Ubhala i-zero
- Ukupasa 2: Ubhala umlinganisi ongenakwenzeka kwaye uqinisekise ukubhala
Yile ndlela iHMG IS5 Enhanced ngokuqhelekileyo isebenza ngayo:
- Ukupasa 1: Ubhala i-zero
- Ukupasa 2: Ubhala enye
- Ukupasa 3: Ubhala umlinganisi ongenanto kwaye uqinisekise ukubhala
I-HMG IS5 iphakanyisiwe iphantse ifana ne- DoD 5220.22-M yeendlela zokuhlanjululwa kwedatha ngaphandle kokuba iipasiti ezimbini zokuqala azidingi ukuqinisekiswa. Kwakhona kufana kakhulu neCSEC ITSG-06 , ebhala enye okanye i-zero kwiipaseli zokuqala ezimbini kwaye igqiba kunye nomntu ongenangqangi kunye nokuqinisekisa.
Xa kuqinisekiswe ukuba kuqinisekiswe nge-HMG IS5 ukudlula, kuthetha ukuba inkqubo kufuneka iqinisekise ukuba idilesi ibhalwe ngaphezulu. Ukuba ukuqiniseka kwehluleka, le nkqubo iya kubakho kwakhona ukuba idlule okanye ikunike isaziso sokuba ayigqibekanga kakuhle.
Qaphela: Ezinye iinkqubo zokutshatyalaliswa kwedatha kunye neefayili zefayile zikuvumela ukuba udale indlela yakho yokususa isiko. Ngokomzekelo, unokongeza iipasiti enye zezinto ezingenangqungquthela kunye nokuhamba kweethathu zeros, okanye nayiphi na into oyithandayo. Ngoko ke, unokukwazi ukhethe i-HMG IS5 uze wenze utshintsho oluthile kuyo ukuze wenze oko. Nangona kunjalo, nayiphina indlela yokususa eyahlukileyo kwizinto ezichazwe ngasentla apha ngeyona ndlela i-HMG IS5.
Iinkqubo ezixhasa i-HMG IS5
I-Eraser , iDiskSula , kunye neSula iiFayile zihlala zizintlu zokusebenza ezikhululekile ezikuvumela ukucima idatha usebenzisa i-HMG IS5 ye-sanitization data. Ezinye iiprogram ezifana nalezi zikhona, kodwa zikhululekile okanye zikhululekile ngexesha lovavanyo, njengeKillDisk.
Njengoko ndithethe ngasentla, ezinye iinkqubo zikuvumela ukuba wakhe indlela yokwenza ucwangco kwedatha. Ukuba unenkqubo exhasa iindlela eziqhelekileyo kodwa kungabonakali kukuvumela ukuba usebenzise i-HMG IS5, unokukwazi ukwenza enye ifanayo usebenzisa iipasiti ezifanayo ndichazwe kwicandelo elidlulileyo.
Uninzi lweenkqubo zokubhubhisa idatha luxhasa iindlela ezininzi zokuncedisa ukuhlanjululwa kwedatha ngokungezelela kwi-HMG IS5. Oku kuthetha ukuba unokuvula enye yale nkqubo, njengabo endiyithandayo ngasentla, kwaye ukhethe indlela eyahlukileyo yokuhlanjululwa kwedata ukuba emva koko ugqibe ukusebenzisa enye into ngaphandle kwe-HMG IS5.
Olongezelelweyo NgeHMG IS5
Inkqubo ye-HMG IS5 yokuhlanjululwa kwe-sanitization yayichazwe ekuqaleni kwi- HMG IA / IS 5 UkuSungulwa koNgcoliseko lweNkcazelo engumGaqo-nkqubo okanye iNgcaciso yengcaciso, epapashwe yiQumrhu loKhuseleko loXwebhu (i-CESG), inxalenye yeKomkhulu leNxibelelwano kaRhulumente wase-UK (GCHQ).
