Data Integrity vs Data Security
Cov ntaub ntawv yog cov cuab tam tseem ceeb tshaj plaws rau txhua lub koom haum. Yog li ntawd, nws yuav tsum tau ua kom paub tseeb tias cov ntaub ntawv siv tau thiab ruaj ntseg txhua lub sijhawm. Cov ntaub ntawv ncaj ncees thiab cov ntaub ntawv kev ruaj ntseg yog ob qho tseem ceeb ntawm kev ua kom cov ntaub ntawv siv tau los ntawm nws cov neeg siv xav tau. Cov ntaub ntawv ncaj ncees ua kom paub tseeb tias cov ntaub ntawv siv tau. Cov ntaub ntawv kev ruaj ntseg ua kom paub tseeb tias cov ntaub ntawv tiv thaiv kev poob thiab tsis tau tso cai nkag.
Data Integrity yog dab tsi?
Data Integrity txhais cov ntaub ntawv zoo, uas lav cov ntaub ntawv tiav thiab muaj tag nrho cov qauv. Cov ntaub ntawv kev ncaj ncees feem ntau yog tham txog kev hais txog cov ntaub ntawv nyob hauv databases, thiab hu ua database kev ncaj ncees thiab. Cov ntaub ntawv kev ncaj ncees tsuas yog khaws cia yog tias thiab thaum cov ntaub ntawv txaus siab tag nrho cov kev cai lag luam thiab lwm cov cai tseem ceeb. Cov kev cai no yuav ua li cas txhua daim ntaub ntawv muaj feem cuam tshuam rau ib leeg, kev siv tau ntawm cov hnub, kab, thiab lwm yam. Raws li cov ntaub ntawv tsim qauv, kev ua haujlwm xws li kev hloov pauv cov ntaub ntawv, cov ntaub ntawv khaws cia, metadata khaws cia thiab cov kab ke khaws cia yuav tsum tau lees paub qhov tseeb ntawm cov ntaub ntawv. Qhov ntawd txhais tau tias, cov ntaub ntawv ncaj ncees yuav tsum tau khaws cia thaum hloov chaw, khaws cia thiab rov qab.
Yog cov ntaub ntawv kev ncaj ncees raug khaws cia, cov ntaub ntawv tuaj yeem txiav txim siab zoo ib yam thiab tuaj yeem muab kev lees paub los lees paub thiab sib haum. Nyob rau hauv cov nqe lus ntawm cov ntaub ntawv kev ncaj ncees nyob rau hauv databases (database integrity), thiaj li yuav lav tau tias kev ncaj ncees yog khaws cia, koj yuav tsum xyuas kom meej tias cov ntaub ntawv los ua ib tug tseeb xav txog ntawm lub ntug nws yog ua qauv tom qab. Hauv lwm lo lus, nws yuav tsum xyuas kom meej tias cov ntaub ntawv khaws cia hauv cov ntaub ntawv sib raug raws nraim rau lub ntiaj teb tiag tiag cov ntsiab lus nws tau ua qauv tom qab. Qhov chaw ncaj ncees, kev ncaj ncees kev ncaj ncees thiab kev ncaj ncees yog ntau hom kev ntseeg siab uas siv los khaws cov ntaub ntawv kev ncaj ncees hauv cov ntaub ntawv.
Data Security yog dab tsi?
Cov ntaub ntawv kev ruaj ntseg cuam tshuam nrog kev tiv thaiv cov ntaub ntawv kev noj nyiaj txiag los ntawm kev siv cov txheej txheem tswj kev nkag. Cov ntaub ntawv kev ruaj ntseg ua kom paub tseeb tias cov ntaub ntawv nkag los ntawm nws cov neeg siv xav tau, yog li ua kom muaj kev ceev ntiag tug thiab kev tiv thaiv ntawm tus kheej cov ntaub ntawv. Ob peb technologies yog siv los xyuas kom meej cov ntaub ntawv kev ruaj ntseg. OTFE (on-the-fly-encryption) siv cov txheej txheem cryptographic rau encrypting cov ntaub ntawv ntawm hard drives. Kho vajtse raws li kev ruaj ntseg daws teeb meem tiv thaiv tsis tau txais kev tso cai nyeem / sau cov ntaub ntawv thiab yog li muab kev tiv thaiv zoo dua piv rau software raws li kev ruaj ntseg daws teeb meem. Vim hais tias software raws li kev daws teeb meem yuav tiv thaiv cov ntaub ntawv poob lossis nyiag tab sis tsis tuaj yeem tiv thaiv kev tsis ncaj ncees (uas ua rau cov ntaub ntawv rov qab tsis tau / siv tsis tau) los ntawm hacker. Kho vajtse raws li ob yam kev tso cai schemes muaj kev ruaj ntseg heev vim hais tias tus attacker xav tau lub cev nkag mus rau cov cuab yeej thiab qhov chaw. Txawm li cas los xij, cov dongles tuaj yeem raug nyiag thiab siv los ntawm yuav luag txhua tus neeg. Thaub cov ntaub ntawv kuj tseem siv los ua ib lub tswv yim tiv thaiv cov ntaub ntawv poob. Cov ntaub ntawv npog yog lwm txoj kev siv rau kev ruaj ntseg cov ntaub ntawv uas cov ntaub ntawv tsis pom. Qhov no yog ua los tswj kev ruaj ntseg thiab rhiab heev ntawm tus kheej cov ntaub ntawv tiv thaiv tsis tau tso cai. Cov ntaub ntawv tshem tawm yog txoj hauv kev sau cov ntaub ntawv los xyuas kom meej tias cov ntaub ntawv tsis raug xau tom qab nws lub neej dhau mus.
Dab tsi yog qhov sib txawv ntawm Cov Ntaub Ntawv Kev Ntseeg thiab Cov Ntaub Ntawv Kev Ruaj Ntseg?
Cov ntaub ntawv kev ncaj ncees thiab cov ntaub ntawv kev ruaj ntseg yog ob qhov sib txawv uas ua kom paub tseeb tias cov ntaub ntawv siv tau raug khaws cia txhua lub sijhawm. Qhov sib txawv tseem ceeb ntawm kev ncaj ncees thiab kev ruaj ntseg yog tias kev ncaj ncees cuam tshuam nrog kev siv tau ntawm cov ntaub ntawv, thaum kev ruaj ntseg cuam tshuam nrog kev tiv thaiv cov ntaub ntawv. Thaub qab, tsim kom haum cov neeg siv kev sib cuam tshuam thiab kev tshawb nrhiav qhov yuam kev / kho cov ntaub ntawv yog qee qhov txhais tau tias khaws kev ncaj ncees, thaum kev lees paub / kev tso cai, encryptions thiab masking yog qee qhov nrov txhais tau tias kev ruaj ntseg cov ntaub ntawv. Cov txheej txheem tswj tau tsim nyog siv tau rau kev ruaj ntseg thiab kev ncaj ncees.
