Cov ntsiab lus ntawm HMG IS5 Cov Ntawv Cuam Tshuam Txog
HMG IS5 (Infosec Standard 5) yog software raws li cov ntaub ntawv khaws cia hauv qee cov ntaub ntawv shredder thiab cov ntaub ntawv kev puas ntsoog rau kev sau cov ntaub ntawv tseem ceeb ntawm ib qho chaw tsav tsheb los yog lwm qhov chaw cia khoom.
Tawm tswv yim siv lub HMG IS5 cov ntaub ntawv yuav tsum tsis txhob siv 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 cov khoom kho raws li kev rho tawm cov ntaub ntawv.
Cov ntaub ntawv no los so txoj kev los ntawm ob yam zoo sib xws - HMG IS5 Baseline thiab HMG IS5 Enhanced . Kuv piav qhia lawv qhov txawv hauv qab no, nrog rau cov kev pabcuam uas siv cov ntaub ntawv no.
Lub HMG IS5 Coj Ua Li Cas?
Qee cov ntaub ntawv so tsuas sau ib qho xoom tshaj cov ntaub ntawv, xws li sau ntawv Xoom . Lwm tus zoo li Random Data tsuas siv random cim. Txawm li cas los xij, HMG IS5 sib txawv me ntsis vim nws muab ob qho tib si.
Cov ntaub ntawv HMG IS5 Cov ntaub ntawv cia rau hauv txoj hauv kev yog siv raws li hauv qab no:
- Kis 1: Sau ntawv xoom
- Dhau 2: Sau ib tug cim ua cim thiab xyuas qhov kev sau ntawv
Qhov no yog li cas HMG IS5 Enhanced feem ntau ua haujlwm:
- Kis 1: Sau ntawv xoom
- Kis 2: Sau ib tug
- Kis 3: Sau ib tug cim ua cim thiab xyuas qhov sau
HMG IS5 Qhov kev ua zoo yuav luag zoo ib yam li cov neeg tsis muaj npe hauv DoD 5220.22-M ntaub ntawv tshwj tsis yog tias thawj ob zaug uas tsis tas yuav tsum muaj pov thawj. Nws kuj zoo ib yam li CSEC ITSG-06 , uas sau ib qho los yog xoom rau thawj ob qho dhau los thiab tom qab ntawd tiav nrog ib qho cim thiab kev pom tseeb.
Thaum kev kuaj xyuas yuav tsum muaj daim ntawv HMG IS5, nws txhais tau hais tias qhov kev zov me nyuam xav tau kev tshawb xyuas tias cov ntaub ntawv tau muaj overwritten. Yog tias qhov tseeb tsis muaj tseeb, qhov kev zov me nyuam yuav ntxias rov qab dua los yog muab ib qho kev ceeb toom rau koj tias nws tsis ua tiav.
Lus Cim: Qee cov ntaub ntawv kev rhuav tshem cov ntaub ntawv thiab cov ntaub ntawv shredders cia koj tsim koj tus kheej kev cai so txoj kev. Piv txwv, koj tuaj yeem tau ntxiv ib qho ntawm cov cim cim thiab tom qab ntawd peb dhau ntawm zeros, los yog koj nyiam. Yog li ntawd, tej zaum koj yuav xaiv tau HMG IS5 thiab tom qab ntawd ua ob peb qhov kev hloov rau nws ua koj tus kheej. Txawm li cas los xij, txhua txoj hauv kev uas sib txawv los ntawm qhov kev piav qhia saum toj no yog kev tsis muaj HMG IS5.
Cov Kev Pabcuam Uas Pab HMG IS5
Lwv Xwb , Pov Tseg , thiab Rho Tawm Ntaub Ntawv Txwv tsis pub muaj ob peb daim ntawv pub dawb uas qhia rau koj tshem tawm cov ntaub ntawv uas siv HMG IS5 cov ntaub ntawv tu tsiaj. Lwm cov kev pabcuam xws li cov no muaj dhau, tabsis lawv tsis pub dawb los yog tsuas pub dawb rau lub sijhawm sib tw, zoo li KillDisk.
Ib yam li kuv hais saum toj no, qee qhov kev pab cuam cia koj tsim koj tus kheej cov ntaub ntawv cia. Yog tias koj muaj qhov kev pab cuam txhawb cov kev cai tiam sis nws tsis zoo li cia koj siv HMG IS5, koj tuaj yeem ua ib qho uas zoo ib yam uas siv tib cov ntawv uas kuv tau piav qhia hauv seem dhau los.
Feem ntau cov ntaub ntawv kev puas tsuaj pab txhawb ntau txoj kev kho cov ntaub ntawv hauv kev ntxiv rau HMG IS5. Qhov no txhais tau tias koj tuaj yeem qhib tau ib qho ntawm cov kev pabcuam no, zoo li cov uas kuv nyiam tshaj rau saum toj no, thiab xaiv lwm cov ntaubntawv tu lub cev yog tias koj tomqab txiavtxim siab siv lwm yam uas tsis yog HMG IS5.
Ntxiv rau HMG IS5
Lub HMG IS5 qhov kev kho mob tau raug muab sau rau hauv HMG IA / YOG 5 Secure Sanitization ntawm Cov Lus Qhia Txog Cov Lus Cog Tseg lossis Cov Ntaub Ntawv Cuam Tshuam , luam tawm los ntawm Communications-Electronics Security Group (CESG), ib feem ntawm lub Tsev Tsoom Fwv Tswj Kev Ncaj Ncees (GCHQ).
