Iinkcukacha kwiNkqubo ye-NCSC-TG-025 yokuSula idatha
I-NCSC-TG-025 yinkqubo esekelwe kwisetyenziswe kwindlela yokuhlanjululwa kwedatha esetyenziswe kwezinye iifayile ze-shredder kunye nedatha yokutshatyalaliswa kwedatha ukuba ibhale ngaphezulu ulwazi olukhoyo kwi- hard drive okanye enye ifowuni yokugcina.
Ukutshabalalisa i-hard drive usebenzisa indlela ye-NCSC-TG-025 yokuhlanjululwa kwedatha iya kuthintela zonke iindlela zokubuyisela iifayile ezisekelwe kwi-software ukusuka ekuphakanyiseni ulwazi kwi-drive kwaye kuya kunokwenzeka ukukhusela iindlela ezininzi zokubuyisela ezisekhompyutheni ukusuka ekukhutshweni kolwazi.
Ngaphantsi kolwazi oluninzi kule ndlela yokufakela idatha njengendlela isebenza ngokuqhelekileyo kunye nezinye iinkqubo ezivumela ukuba usebenzise.
Yintoni eyenziwa yi-NCSC-TG-025?
I-NCSC-TG-025 ifana nezinye iinkqubo zokucocwa kweedatha kwinto yokuba idlula idatha malunga nanye kanye ukuze ibhale ngaphezulu ngeyimbo, enye, okanye isalathisi. Nangona kunjalo, le ndlela ayifani nezinye iindlela ezifana nokubhala iZero ezigqithiseleyo ulwazi nge-zero, okanye i- Random Idatha esebenzisa kuphela iilwimi ezingenanto.
Endaweni yoko, i-NCSC-TG-025 isetyenziswa ngokuqhelekileyo ngendlela elandelayo, ukudibanisa ii-zeros, kunye neentlobo ezingenanto:
- Ukupasa 1: Ubhala i-zero kwaye uqinisekise ukuba ubhala
- Ukupasa 2: Ubhala omnye aze aqinisekise ukubhala
- Ukupasa 3: Ubhala umlinganisi ongenanto kwaye uqinisekise ukubhala
Indlela ye-santification ye-NCSC-TG-025 ifana ne- DoD 5220.22-M nendlela kunye nendlela eya kuphunyezwa ngayo iya kufana.
Njengoko uyakubona, inkqubo esebenzisa le ndlela yokwenza ifayile isula iyakwazi ukuqinisekisa ukuba idatha yachithwa ngempumelelo ngaphambi kokuba idlulele kwi-pass elandelayo. Ukuba ibhaliwe engagqibekanga ngesizathu esithile, isofthiwe izakuphinda iphinde iphinde idlulise ididithi ethile ize iqinisekise ukuba idatha ibhalwe ngaphezulu, okanye inokukuxelela nje ukuba ukuqinisekiswa akuzange kugqibezele njengoko kulindeleke ukuba wena unokuyivuselela ngesandla xa ufuna.
Qaphela: Ezinye iinkqubo ezixhasa idatha ukususa iindlela ezifana ne-NCSC-TG-025 inokukuvumela ukuba wakhe ngokwakho. Ngokomzekelo, unokongeza ama-passes of zero ngaphezulu xa ungathanda, okanye ususe ukuqinisekiswa kwipasithi nganye.
Nangona kunjalo, nayiphina indlela oyenzayo eyahlukileyo kwinto ebhaliweyo ngasentla ingeyona ye-NCSC-TG-025 yeendlela zokucocwa kwedatha. Ukuba ukhethe oku okwaneleyo, unokwakha indlela eyahlukileyo, njengeVSITR okanye iSchneier , okanye ngokwenene nayiphina indlela kuxhomekeke ekubeni ungatshintsha kangakanani.
Iinkqubo ezixhasa iNCSC-TG-025
Nangona mhlawumbi kuninzi nabanye, i- File Shredder ithuluzi kwi-WinUtilities yinkqubo enye ye-free evumela ukuba usebenzise indlela ye-NCSC-TG-025 yokuhlanjululwa kwe-sanitization. Ayikwazi ukususa kuphela iifayile ezithile kodwa kwakhona iifolda kunye neenjini ezikhuni.
Enye ifowuni exhasa le ndlela yokususa idatha yiDisk Shredder, kodwa ayikhululekile.
Uninzi lweenkqubo zokubhubhisa idatha luxhasa iindlela ezininzi zokuncedisa ukuhlanjululwa kwedatha ngokungezelela kwi-NCSC-TG-025. Nge-WinUtilities, umzekelo, unokusebenzisa indlela yeNSA yedlulisa idatha kunye ne-DOD 5223-23M, Guttman , njl.
Njengoko ufunde ngasentla, ezinye izicelo zikuvumela ukuba wakhe indlela yokuhlanjululwa kwesimo. Ngoko ke, ukuba inkqubo ikuvumela ukuba wakhe ngokwakho kodwa ayibonakali ibonakala ukuba isekela i-NCSC-TG-025, unokulandela nje iphethini efanayo njengentla ngasentla ukwenzela ukuba iziphene zifane.
Okunye malunga ne-NCSC-TG-025
Indlela ye-NCSC-TG-025 yokuhlanjululwa kwe-sanitization yayichazwe ekuqaleni kwi- Forest Green Book , inxalenye ye- Rainbow Series yezikhokelo zokhuseleko lwekhompyutheni, eyapapashwa yiSizwe soKhuseleko lweSizwe seKhompyutha (i-NCSC), iqela elalisakuba yinxalenye ye-US National Security Agency (NSA).
Qaphela: i- NCSC-TG-025 ayisona mgangatho wokuncedisa i-NSA. Incwadana ye-NSA / CSS yokuLondolozwa kweDiscosi yedivayisi (iNSA / i-CSS SDDM) iluhlu kuphela ukutshabalalisa nokubhubhisa ngokwenyama ngokutshatyalaliswa njengoko iindlela zeNSA zivunyelwe ukuba zihlalutye idatha yedatha.
