DoD 5220.22-M ndidongosolo lothandizira njira zothandizira anthu kugwiritsa ntchito njira zowonongeka pogwiritsa ntchito mafayilo osiyanasiyana omwe amawotchera mafayilo ndi zina zowonongeka kuti alembetse zambiri zomwe zilipo pa hard drive kapena chipangizo china chosungirako.
Kutaya galimoto yolimba pogwiritsira ntchito njira ya Dothi 5220.22-M njira yothandizira kusokoneza deta kudzatchinjiriza njira zonse zopezera mafayilo njira zowonongolera zomwe zimachokera ku kuchotsa uthenga kuchokera pa galimotoyo komanso ziyenera kuteteza njira zambiri zowonongeka.
Njira ya DoD 5220.22-M nthawi zambiri imatchulidwa molakwika monga DoD 5220.2-M (.2-M mmalo mwa .22-M).
DoD 5220.22-M Njira Yopukuta
Njira ya Dongosolo 5220.22-M yowononga njira zambiri imayendetsedwa motere:
- Pepani 1: Kulemba zero ndikuwatsimikizira kulemba
- Pepani 2: Alemba chimodzi ndikuwonetsa kulemba
- Kupita 3: Kulemba khalidwe losavuta ndikuwonetsa kulemba
Mukhozanso kupeza njira zosiyanasiyana za DoD 5220.22-M kuphatikizapo DoD 5220.22-M (E), DoD 5220.22-M (ECE), kapena ena. Aliyense angagwiritse ntchito chikhalidwe ndi kuyamikiridwa kwake (monga 1 ndi 0) ndi maulendo osiyanasiyana a maumboni.
Ngakhale kuti sichidziwikiratu, pali DPD 5220.22-M yomwe inalembera 97 patsiku lotsiriza m'malo mwa khalidwe losavuta.
Mapulogalamu Opanda Ntchito Amene Amagwiritsa Ntchito DoD 5220.22-M Njira Yopukutira
Pali mapulogalamu ambiri omwe ali ndi mwayi wogwiritsira ntchito mlingo wa DoD 5220.22-M kukonza chiyanjano chochotsa zonsezi kuchokera ku hard drive.
Chinthu chomwe ndimachikonda kwambiri chochotsera deta chogwiritsira ntchito DoD 5220.22-M, mwa njira zina, ndi DBAN , koma ena ochepa amakhala ndi mwayi, monga CBL Data Shredder .
Pamene mukuwerenga pamwambapa, ena amapanga mapulogalamu omwe amawongolera mafayilo osankhidwa amodzi kapena oposa ambiri, komanso amagwiritsa ntchito DoD 5220.22-M.
Zitsanzo za ophwanya mafayilo aufulu omwe ali ndi mwayi wa DoD 5220.22-M yochokera fayilo yojambulira ndikuphatikizapo Eraser , Mobisa Frederer , ndi Freeraser .
Zambiri Zokhudza DoD 5220.22-M
Njira ya Dothi 5220.22-M yomwe poyamba inalembedwa ndi US National Industrial Security Program (NISP) m'buku la National Industrial Security Program (OPP), yomwe ili pano (iyi ndi PDF ), ndipo ndi imodzi mwa njira zowonongeka kugwiritsa ntchito pulogalamu yawononga data.
Zambiri zowonongeka kwa deta zimathandiza njira zambiri zothandizira anthu kuphatikizapo DoD 5220.22-M, monga Kutsekemera kosavuta, kulemba Zero , Random Data ndi Schneier .
Zindikirani: NISPOM sichikutanthauzira chiyero chilichonse cha boma cha US cha kusokoneza deta. Cognizant Security Authority (CSA) ndi amene amayang'anira miyezo yothandizira anthu kuti asamangidwe.
Monga ndikudziwira, njira ya DoD 5220.22-M sichiloledwa (kapena njira iliyonse yothandizira kusokoneza deta) kuti agwiritsidwe ntchito ndi anthu osiyanasiyana a CSA kuphatikizapo Dipatimenti ya Chitetezo, Dipatimenti ya Energy, Nuclear Regulatory Commission, ndi Central Intelligence Agency.
Kodi DoD 5220.22-M Ndi Yosavuta Kuposa Njira Zina?
Ziribe kanthu zonse zomwe deta zimawononga njira yomwe mumagwiritsira ntchito. Popeza ambiri a ife omwe tikupukuta ma drive athu akungopanga zisanayambe kugulitsa galimoto kapena kukhazikitsa OS yatsopano, siziyenera kukhala zodetsa nkhaŵa zazikulu monga momwe zingapo zing'onozing'ono zimakhala zolembedwera ku galimoto kupyolera pa zino kapena zero .
Kuwonjezera apo, anthu ambiri omwe amayesa kubwezeretsa deta kuchokera ku galimoto yoyendetsa yogula amagwiritsira ntchito zipangizo zamakono monga Recuva , ndipo pamene akugwira ntchito pofufuzira deta, iwo samachita bwino pamene deta amapukuta njira.
Komabe, posankha njira yothandizira kusokoneza deta, mungaganizire kuti zitenga nthawi yaitali bwanji kuti muwononge galimotoyo. Ngati muli ndi galimoto yochuluka kwambiri, lembani Zero idzatenga nthawi yochepa kuti mutsirize kuposa DoD 5220.22-M, yomwe idzafulumira kwambiri kuposa Gutmann yomwe imatha kudutsa kupitirira 30.
Onaninso ngati zowonjezera zimachitika pambuyo pa maulendo. Popeza mapulogalamu ena amatha kugwiritsa ntchito njira ya DoD 5220.22-M m'njira yomwe imatsimikizira aliyense kulemba kumapeto kwa patsiku lililonse, ndondomeko yonse idzatenga nthawi yaitali kusiyana ndi kugwiritsa ntchito njira yosafanizira yosavomerezeka konse (monga yotetezeka) kapena akudikirira mpaka kutha kwa patsiku lomaliza kuti atsimikizire kuti deta yalembedwa.
Chinthu china chomwe chingagwiritse ntchito njira yomwe mumagwiritsira ntchito ndi deta lenileni yomwe amagwiritsidwa ntchito kulembetsa dalaivala. Ena amapukuta njira, monga kulembera Zero, gwiritsani ntchito zero mmalo mwa zilembo zosasintha. N'zotheka kuti kugwiritsa ntchito malemba osasinthasintha kumachititsa kuti chiwerengero chisawonongeke.
