Yog Schneier Txoj Kev Ib Txoj Kev Zoo rau Lawm Cov Ntaub Ntawv?
Txoj kev Schneier yog ib qho software uas muaj nyob hauv cov ntaub ntawv siv rau hauv cov ntaub ntawv qis thiab cov ntaub ntawv kev rhuav tshem cov ntaub ntawv kom sau tau cov ntaub ntawv tseem ceeb ntawm cov tsav tsheb lossis lwm yam khoom siv.
Kev quab yuam kev siv lub Schneier data sanitization txoj kev yuav tiv thaiv tag nrho cov software raws li cov ntaub ntawv rov qab los ntawm kev nrhiav cov lus qhia ntawm tus tsav thiab tseem yuav los tiv thaiv feem ntau ntawm kev kho vajtse rov los ntawm extracting cov ntaub ntawv.
Hauv ntej, tus Schneier txoj kev overwrites cov ntaub ntawv ntawm ib tug cia cov khoom siv nrog ib tug, thiab tom qab ntawd ces xoom, thiab thaum kawg nrog ob peb ntawm cov cim random. Muaj ntau yam ntxiv rau hauv qab no, nrog rau ob peb qhov qauv ntawm cov kev pab cuam nrog Schneier txoj kev raws li kev xaiv thaum tshem tawm cov ntaub ntawv.
Txoj Cai Schneier Ua Dab Tsi?
Tag nrho cov ntaub ntawv kev tu tsiaj txhuam ua haujlwm zoo ib yam tab sis lawv tsis yog ib txwm siv rau tib txoj kev. Piv txwv li, Sau Xoom txoj kev sau cov ntaub ntawv ua ke nrog cov zauv xwb. Lwm tus, zoo li Random Data , cia li siv random cim. HMG IS5 zoo heev nyob rau hauv tias nws sau ib qho xoom, ces ib tug, thiab ces ib tug cim ua cim, tab sis tsuas yog ib qho ntawm ib tug cim ua cim.
Txawm li cas los xij, nrog Schneier txoj kev, muaj ntau yam ua ke ntawm ntau cov cim ntawm cov cim ua cim zoo li ntawm zero thiab sawv daws. Qhov no yog li cas nws yog feem ntau DVR:
- Dhau 1: Sau ib daim
- Dhau 2: Sau ntawv xoom
- Dhau 3: Sau ib kwj deg ntawm cov cim cim
- Dhau 4: Sau ib kwj ntawm cov cim cim
- Kis 5: Sau ib kwj ntawm cov cim cim
- Dhau 6: Sau ib kwj deg ntawm cov cim cim
- Pass 7: Sau ib kwj ntawm cov cim cim
Qee qhov kev pab cuam siv tau Schneier txoj kev nrog kev hloov me me. Piv txwv, qee cov ntawv thov kev pab yuav txhawb qhov kev kuaj xyuas tom qab thawj zaug los sis dhau qhov dhau. Dab tsi yog qhov tseeb hais tias tus ua cim, xws li ib tus cim los sis cov cim ua cim, nws tau sau rau tus tsav tsheb. Yog hais tias nws tsis yog, software yuav qhia koj los yog cia li tau pib dua thiab khiav los ntawm cov kis dua.
Ntsis: Muaj qee qhov kev pab cuam uas cia koj hloov koj cov kev cai, xws li ua qaum xaj sau tom qab Pass 2. Txawm li cas los xij, yog tias koj hloov txaus rau Schneier txoj kev, nws tsis tshua ua nyob ntawd . Piv txwv li, yog tias koj tshem tawm thawj ob kis thiab ces ntxiv ntau hom cim dua qub, koj yuav tau tsim Gutmann txoj kev .
Cov kev pab cuam uas txhawb Schneier
Ntau cov kev pab cuam sib txawv pub koj siv Schneier txoj kev los tshem tawm cov ntaub ntawv. Ob peb cov piv txwv yog Eraser , Securely File Shredder , CBL Data Shredder , CyberShredder, Rho Tawm Ntaub Ntawv Txuas Mus, thiab Dawb EASIS Data Eraser.
Txawm li cas los xij, zoo li peb hais saum toj no, qee cov ntaub ntawv shredders thiab cov ntaub ntawv kev puas ntsoog tso cai rau koj hloov kho dab tsi mus thaum lub sijhawm dhau. Qhov no txhais tau hais tias txawm tias lawv tsis muaj txoj kev ua no, koj tseem "tsim tau" Schneier txoj hauv cov kev pabcuam uas siv cov qauv saum toj no.
Feem ntau cov ntaub ntawv kev rhuav tshem cov ntaub ntawv pab txhawb ntau cov ntaubntawv khaws cia cov ntaub ntawv ntxiv rau Schneier txoj kev. Yog tias koj xav tau, koj tuaj yeem khaws cov ntaub ntawv sib txawv dua qub thaum koj muaj qhov qhoos kas qhib.
