Imininingwane ye-Pfitzner Data Data Wipe Method
Indlela ye-Pfitzner iyi-software esekelwe idatha ye-sanitization yedatha eyakhiwe nguRoy Pfitzner ngokususa idatha kusuka ku- hard drive noma kwenye idivayisi yesitoreji.
Ukusebenzisa indlela ye-sanitization yedatha ye-Pfitzner kuzovimbela zonke izindlela zokubuyisela ifayela ezisekelwe kwikhompyutha ukuthola ulwazi mayelana nokushayela, futhi kungenzeka ukuthi zivimbele izindlela eziningi zokutakula ezisetshenziswa ngekhompyutha kusukela ekukhipheni ulwazi.
Izinhlu zethu zezinhlelo zokusebenza ze-shredder nezinhlelo zokubhujiswa kwedatha kufaka phakathi isofthiwe esebenzisa izindlela zokuhlanza idatha njengePfitzner ukuze ibhale phansi amanye amafayela kudivayisi yokugcina noma ngokuphelele into, kuhlanganise lonke uhlelo lokusebenza .
Indlela yePfitzner isebenza kanjani?
Kunezindlela eziningi ezahlukene zokusula idatha futhi ngamunye uyahamba ngokusula idatha nje kancane ehlukile kunezinye. Isibonelo, abanye bangasebenzisa ama-zero nje njenge- Write Zero , ama-zero kanye nalabo abanjengoSiphephelo Esilondekile , noma inhlanganisela yama-zero, lawo, nezinhlamvu ezingahleliwe, njengezindlela ze- VSITR ne- Schneier .
Yize isofthiwe eminingi isebenzisa indlela yePfitzner ngale ndlela elandelayo, abanye bangayishintsha futhi basebenzise inombolo encane yamaphasi (okuyisikhombisa kuvamile):
- Dlula 1 - 33: Ubhala uhlamvu olungahleliwe
Ngezinye izikhathi kubhaliwe njengo- Pfitzner 33-pass , Pfitzner 7-pass , okungahleliwe (x33) noma okungahleliwe (x7).
Ithiphu: Ukwaziswa okungahleliwe kanye no- Gutmann ngendlela efanayo kakhulu ku-Pfitzner ngoba bobabili basebenzise izinhlamvu ezihleliwe kuphela ukuze babhale phansi idatha, umahluko wabo ulele nje ukuthi zingaki ezedlule.
"Ukudlula" kumane nje ukuthi indlela iqhutshwa kangaki. Ngakho esimweni se-Pfitzner, esinikezwe ukuthi i-overwrites idatha ngezinhlamvu ezingahleliwe, yenza njalo noma kabili kodwa izikhathi ezingu-33 ezihlukene.
Ngaphezu kwalokhu, isofthiwe eminingi izokuvumela ukuba ugijime indlela ye-Pfitzner okungaphezu kwesisodwa. Ngakho uma ufanele usebenze ngale ndlela izikhathi ezingu-50 (okuyiqiniso ukuthi i-overkill), isofthiwe izobe ibhalwe phansi ngokuphindaphinda izikhathi ezingu-33, kodwa izikhathi ezingu-1,650 (33x50)!
Ezinye izinhlelo zokubhujiswa kwedatha zingabuye ziqinisekise ukudlula ngemuva kokuqedela. Lokhu kusho nje ukuthi isofthiwe ihlola ukuthi ulwazi lwalubhalwe phansi ngezinhlamvu ezingahleliwe (noma yiziphi izinhlamvu indlela esekela ngayo). Uma inqubo yokuqinisekisa ihluleka, uhlelo cishe luzokwazisa noma lusebenze ngokuzenzakalelayo le ndlela kuze kudlule ukuqinisekiswa.
Isofthiwe Esekela I-Pfitzner Method
Indlela ye-santization ye-Pfitzner ayiyona enye ethandwa kakhulu, kodwa kusekhona izinhlelo ezifaka phakathi njengendlela yokukhetha.
I-Catalano Delete Safe is Uhlelo olulodwa olungasebenzisa indlela yePfitzner. Njengeningi lezinhlamvu zefayili kanye nenqubo yokubhujiswa kwedatha, ibuye isekele nezinye izindlela eziningana njenge- NAVSO P-5239-26 , Idatha engahleliwe, AR 380-19 , i- DoD 5220.22-M , ne- GOST R 50738-95 .
Ezinye izinhlelo zokusebenza ezifanayo zihlanganisa i- Securely File Shredder , Freeraser and Eraser . Lezi zinhlelo zingasusa amafayela namafolda athile asebenzisa indlela efanayo kodwa ayifani nePfitzner. Isibonelo, ungakhetha indlela kaGutmann kwenye yalezi zinhlelo ukuze ubhale phansi izikhathi ezingu-35, kepha ayisekeli ngokuqondile indlela yePfitzner.
Uma useMac, i-SecureRemove isekela i-33 pass Pfitzner kanye nezinye izindlela eziningi ezinjenge-4-idlula i-RAZER, i-DoD 5220.22-M (E) ne-GOST R 50739-95.
I-CBL Data Shredder ne- DBAN yizinhlelo ezimbili zokubhujiswa kwedatha ezingakwazi ukubhala yonke i-hard drive (hhayi amafayela / amafolda athile, kodwa yonke into) ngezinhlamvu ezingahleliwe. Ngokulingisa kakhulu ukulinganisa indlela ye-Pfitzner, ngoba akekho kulezi zinhlelo ezisekelayo ngokuqondile, ungase ukwazi ukusebenzisa indlela yokuhlanzeka njenge-Random Data ukusula idrayivu kaningi ngangokunokwenzeka.
I-BitRaser ayikhululekile kepha ifana ne-CBL Data Shredder ne-DBAN futhi empeleni isekela uPfitzner, ngokuqondile.
Ukuhlunga yisibonelo sesimiso esingenza kokubili: ukuhlunga amafayela ngabanye kanye nokushayela wonke ama-hard drive, kuye ngokuthi ukhetha ukuyisebenzisa kanjani.
Ingabe Kufanele Usebenzise I-Pfitzner Method?
U-Roy Pfitzner, umdali wale ndlela yokusula idatha, uthe idatha ingakwazi ukubuyiswa uma ibhalwe phansi izikhathi ezingu-20 kuphela, nokuthi ukubhala izinhlamvu ezingahleliwe izikhathi ezingaba ngu-30 kufanele zanele. Noma kunjalo, ngabe lokhu kunembile yini ukuphikisana.
Kuye kwathiwa ukuthi inani lamaphesenti alenziwe ngendlela kaGutmann (ebhala izinhlamvu ezingahleliwe izikhathi ezingu-35) akudingekile ngempela ngoba ngisho namaphesenti ambalwa angcono kakhulu umuntu ongakwenza. Ungafunda okuncane ngalokhu lapha: Uyini indlela yeGutmann? .
