Imininingwane ye-NCSC-TG-025 Indlela yokusula idatha
I-NCSC-TG-025 iyi-software esekelwe idatha ye-sanitization yedatha esetshenzisiwe kwezinye izinhlelo zefayela zokuhlenga nokudlula idatha ukuze ubhale ulwazi olukhona ku- hard drive noma kwenye idivayisi yesitoreji.
Ukulahla i-hard drive usebenzisa indlela ye-NCSC-TG-025 ye-sanitization yokuvikela idatha kuzovimbela zonke izindlela zokutakula ifayela le-software kusukela ekuphakameni ulwazi kusukela ku-drive futhi kungenzeka nokuvimbela izindlela eziningi zokuthola izinto eziphathekayo zekhompyutha kusukela ekukhipheni ulwazi.
Ngezansi ulwazi oluthe xaxa kulolu hlelo lokusula idatha njengendlela evame ukusebenza ngayo kanye nezinye izinhlelo ezikuvumela ukuthi usebenzise.
Iyini i-NCSC-TG-025?
I-NCSC-TG-025 ifana nezinye izindlela zokunakekelwa kwemininingwane yedatha ngoba idlula idatha okungenani kanye ukuze ibhale ngaphezulu nge-zero, eyodwa, noma uhlamvu oluhleliwe. Noma kunjalo, le ndlela ayifani nezinye izindlela ezifana ne- Write Zero esanda kubhala ulwazi ngolwazi lwe-zero, noma okungahleliwe olusebenzisa kuphela izinhlamvu ezingahleliwe.
Esikhundleni salokho, i-NCSC-TG-025 ivame ukusetshenziswa ngendlela elandelayo, ukuhlanganisa ama-zeros, lawo, nezinhlamvu ezingahleliwe:
- Dlula 1: Ubhala i-zero bese uqinisekisa ukubhala
- Dlula 2: Ubhala futhi uqinisekise ukubhala
- Dlulisa 3: Ubhala umlingisi ongahleliwe futhi uqinisekise ukubhala
Indlela ye-sanitization ye-NCSC-TG-025 ifana ncamashi nendlela yeDoD 5220.22-M kanye nokuhlukahluka kokusetshenziswa kwayo kuyoba okufanayo.
Njengoba ungabona, uhlelo olusebenzisa le ndlela yokwesula idatha cishe luzoqinisekisa ukuthi idatha ibhalwe ngaphezulu ngempumelelo ngaphambi kokuthuthela kudlule. Uma ukubhalisa kungakapheli ngesizathu esithile, isofthiwe cishe izophinde iphinde iphinde idluliselwe ngqo kuze kuqinisekiswe ukuthi idatha ibhalwe phansi, noma ingase ikutshele ukuthi ukuqinisekiswa akuzange kuqede njengoba kulindelwe ukuze wena kungaba ukuyibuyisela ngesandla uma uthanda.
Qaphela: Ezinye izinhlelo ezisekela izindlela zokusula idatha njenge-NCSC-TG-025 zingase zikuvumele ukuthi uzakhe ngokwakho. Isibonelo, ungangeza amaphasi amaningi we-zero ngaphezulu uma ungathanda, noma ususe ukuqinisekiswa kudlule ngalinye.
Noma kunjalo, noma iyiphi indlela oyenzayo ehluke kulokho okubhaliwe ngenhla akuyona indlela ye-NCSC-TG-025 ye-sanitization. Uma wenze ngokwezifiso lokhu okwanele, ungakha indlela ehlukile, njenge- VSITR noma uSchneier , noma impela noma iyiphi indlela kuye ngokuthi ungashintsha kangakanani.
Izinhlelo ezisekela i-NCSC-TG-025
Yize cishe kukhona amanye amaningana, ithuluzi le- File Shredder ku-WinUtilities linye uhlelo lwamahhala oluvumela ukuthi usebenzise indlela ye-NCSC-TG-025 ye-sanitization. Awukwazi ukususa kuphela amafayela athile kodwa futhi nawo wonke amafolda nezinkinobho ezinzima.
Enye uhlelo lokusebenza olusekela le ndlela yokususa idatha i-Disk Shredder, kodwa ayikho mahhala.
Iningi lezinhlelo zokubhujiswa kwedatha lisekela izindlela eziningi zokuhlanza idatha ngaphezu kwe-NCSC-TG-025. Nge-WinUtilities, isibonelo, ungasebenzisa le ndlela ye-NSA yokusula idatha kanye ne-DOD 5223-23M, Guttman , njll.
Njengawe ufunde ngenhla, ezinye izinhlelo zokusebenza zikuvumela ukuthi wakhe indlela yokuhlanzeka yangokwezifiso. Ngakho-ke, uma uhlelo lukuvumela ukuba wakhe ngokwakho kodwa kubonakala sengathi kubonakala ukuthi isekela i-NCSC-TG-025, ungase ulandele iphethini efanayo nje ngenhla ukuze wenze amaphasiwedi afane.
Okuningi mayelana ne-NCSC-TG-025
Indlela ye-sanitization ye-NCSC-TG-02 yaqala ekuqaleni eHhovisi Elihle Lamahlathi , ingxenye ye- Rainbow Series yezinkombandlela zokuphepha kwekhompiyutha, eyanyatheliswa yi-National Computer Security Centre (NCSC), iqembu elakade liyingxenye ye-US National Security Agency (I-NSA).
Qaphela: i- NCSC-TG-025 ayiseyona inqubo ye-sanitization yedatha ye-NSA. I-NSA / CSS Inombolo Yokudambisa Idokhumenti yedivayisi yokugcina (i-NSA / CSS SDDM) ibonisa ukubhujiswa kokudlulela nokubhujiswa komzimba ngokunciphisa njengoba izindlela zeNSA zivunyiwe zokuhlanza idatha yedatha yedrayivu.
