Kev tiv thaiv mechanisms yog siv los tswj cov txheej txheem ntawm kev ntseeg siab ntawm kev ruaj ntseg theem ntawm qhov system. Tshwj xeeb rau kev khiav hauj lwm systems, kev ntseeg siab yog siv los muab ib txoj hauv kev los ua kom cov ntaub ntawv nkag mus thiab tsim ib qho kev txiav txim hierarchical.
Hauv qhov no, kev ruaj ntseg mechanism hauv kev ruaj ntseg network yog dab tsi?
➢ Kev ruaj ntseg Mechanism : A tshuab uas yog tsim los ntes, tiv thaiv, lossis rov qab los ntawm a kev ruaj ntseg nres. ➢ Kev ruaj ntseg Kev Pabcuam: Ib qho kev pabcuam uas txhim kho lub kev ruaj ntseg ntawm cov txheej txheem ua cov ntaub ntawv thiab cov ntaub ntawv hloov chaw. A kev ruaj ntseg kev pabcuam ua rau siv ib lossis ntau dua kev ruaj ntseg mechanisms.
Tsis tas li ntawd, File Protection OS yog dab tsi? tiv thaiv cov ntaub ntawv . Logical tiv thaiv cov ntaub ntawv yog muab los ntawm lub operating system, uas tuaj yeem xaiv cov ntaub ntawv raws li nyeem xwb. Qhov no tso cai rau ob qho tib si tsis tu ncua (nyeem / sau) thiab nyeem nkaus xwb cov ntaub ntawv yuav tsum khaws cia rau tib lub ntim disk. Cov ntaub ntawv tuaj yeem raug xaiv los ua zais cov ntaub ntawv , uas ua rau lawv pom tsis tau rau feem ntau software programs.
Raws li qhov xav tau kev tiv thaiv piav qhia ntau yam kev tiv thaiv kev txhawb nqa los ntawm kev khiav haujlwm?
Cov txheej txheem hauv kev khiav hauj lwm yuav tsum muaj kev tiv thaiv los ntawm ib leeg cov dej num. Txhawm rau muab kev tiv thaiv zoo li no, peb tuaj yeem siv ntau lub tswv yim los xyuas kom meej tias tsuas yog cov txheej txheem uas tau txais kev tso cai los ntawm lub operating system tuaj yeem ua haujlwm ntawm cov ntaub ntawv, ntu ntu, CPU , thiab lwm yam kev pab cuam ntawm lub system.
Koj txhais li cas los ntawm kev ruaj ntseg network?
Kev ruaj ntseg network yog kev tiv thaiv kev nkag mus rau cov ntaub ntawv thiab cov npe hauv computer network tiv thaiv hacking, siv tsis raug thiab kev hloov pauv tsis raug cai rau lub system. Ib qho piv txwv ntawm kev ruaj ntseg network yog ib qho antivirus system. YourDictionary txhais thiab siv piv txwv.

Kev tiv thaiv cov ntaub ntawv yog txheej txheem ntawm kev tiv thaiv cov ntaub ntawv thiab koom nrog kev sib raug zoo ntawm kev sau thiab kev tshaj tawm cov ntaub ntawv thiab thev naus laus zis, kev nkag siab ntawm pej xeem thiab kev cia siab ntawm kev ceev ntiag tug thiab kev nom kev tswv thiab kev cai lij choj nyob ib puag ncig cov ntaub ntawv
NIST SP 800 53 tus txheej txheem kev nyab xeeb dab tsi txhais tau li cas hauv kev tiv thaiv US tsoom fwv?
NIST Kev Tshaj Tawm Tshwj Xeeb 800-53 muab cov ntawv teev npe ntawm kev nyab xeeb thiab kev tswj hwm ntiag tug rau txhua lub tebchaws Asmeskas cov ntaub ntawv xov xwm tshwj tsis yog cov cuam tshuam txog kev ruaj ntseg hauv tebchaws. Nws yog luam tawm los ntawm National Institute of Standards and Technology, uas yog ib lub koom haum tsis tswj hwm ntawm Tebchaws Meskas Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam
Cov txheej txheem kev ruaj ntseg yog dab tsi?
Txheej kev ruaj ntseg, tseem hu ua txheej tiv thaiv, piav qhia txog kev coj ua ntawm kev sib txuas ntau yam kev tiv thaiv kev ruaj ntseg los tiv thaiv cov peev txheej thiab cov ntaub ntawv. Muab cov cuab yeej cuab tam nyob rau hauv lub cheeb tsam innermost yuav muab cov txheej txheem ntawm kev ruaj ntseg ntsuas ntawm qhov kev ncua deb ntawm cov cuab tam tiv thaiv
Dab tsi yog kev ruaj ntseg ruaj ntseg thiab muaj nyob rau hauv kev ruaj ntseg?
Kev ceev ntiag tug txhais tau hais tias cov ntaub ntawv, cov khoom thiab cov peev txheej raug tiv thaiv los ntawm kev tsis pom zoo thiab lwm yam kev nkag. Kev ncaj ncees txhais tau tias cov ntaub ntawv raug tiv thaiv los ntawm kev hloov pauv tsis tau tso cai los xyuas kom meej tias nws ntseeg tau thiab raug. Muaj txhais tau hais tias cov neeg siv tau tso cai nkag tau rau hauv cov tshuab thiab cov peev txheej uas lawv xav tau
Dab tsi yog qhov haujlwm ntawm OSI txheej txheej txheej txheej txheej txheem router ua haujlwm li cas?
Hauv Cov Qauv Qhib Kev Sib Txuas Sib Txuas (OSI) kev sib txuas lus, txheej txheej txheej txheem nyob ntawm Txheej 5 thiab tswj kev teeb tsa thiab rhuav tshem ntawm kev sib txuas ntawm ob qhov kev sib txuas lus kawg. Kev sib txuas lus ntawm ob qhov kawg yog hu ua kev sib txuas
