TDE daws qhov teeb meem ntawm kev tiv thaiv cov ntaub ntawv ntawm so, encrypting databases ob qho tib si ntawm lub hard drive thiab yog li ntawm cov xov xwm thaub qab. Nws tsis tiv thaiv cov ntaub ntawv hauv kev thauj mus los lossis cov ntaub ntawv siv. Cov lag luam feem ntau ntiav TDE los daws cov teeb meem ua raws li PCI DSS uas xav tau kev tiv thaiv cov ntaub ntawv thaum so.
Vim li cas TDE thiaj muaj txiaj ntsig?
Koj tuaj yeem siv Transparent Data Encryption (TDE) txhawm rau txhawm rau SQL Server thiab Azure SQL Database cov ntaub ntawv cov ntaub ntawv thaum so. Nrog TDE koj tuaj yeem encrypt cov ntaub ntawv rhiab hauv cov ntaub ntawv thiab tiv thaiv cov yuam sij uas siv los encrypt cov ntaub ntawv nrog daim ntawv pov thawj.
TDE yog dab tsi thiab vim li cas peb thiaj siv nws?
TDE tiv thaiv cov ntaub ntawv thaum so, uas yog cov ntaub ntawv thiab cov ntaub ntawv teev tseg. Nws tso cai rau koj ua raws ntau txoj cai, cov cai, thiab cov txheej txheem tsim nyob rau hauv ntau yam kev lag luam. Qhov kev muaj peev xwm no tso cai rau cov neeg tsim khoom siv software encrypt cov ntaub ntawv los ntawm kev siv AES thiab 3DES encryption algorithms yam tsis hloov cov ntawv thov uas twb muaj lawm.
TDE tiv thaiv dab tsi?
Lo lus "cov ntaub ntawv thaum so" yog hais txog cov ntaub ntawv, cov ntaub ntawv teev npe, thiab cov ntaub ntawv khaws cia hauv qhov tsis tu ncua. Raws li, TDE tiv thaiv cov neeg phem uas sim rov qab cov ntaub ntawv raug nyiag, xws li cov ntaub ntawv, cav, thaub qab, snapshots, thiab cov ntaub ntawv luam tawm.
TDE ruaj ntseg li cas?
TDE tau koom ua ke nrog Oracle database. Cov ntaub ntawv zais zais tseem nyob hauv cov ntaub ntawv, txawm tias nws yog nyob rau hauv cov ntaub ntawv khaws cia cov ntaub ntawv, cov rooj zaum ib ntus, tshem tawm cov rooj zaum, lossis lwm cov ntaub ntawv uas Oracle Database tso siab rau xws li rov ua cov ntaub ntawv. Tsis tas li, TDE tuaj yeem nkag mus rau tag nrho cov ntaub ntawv thaub qab (RMAN) thiab cov ntaub ntawv xa tawm.
