Transparent Data Encryption (feem ntau abbreviated rau TDE ) yog ib lub tshuab ua haujlwm los ntawm Microsoft, IBM thiab Oracle rau encryption cov ntaub ntawv database. TDE muab encryption ntawm cov ntaub ntawv theem. 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.

Yog li ntawd, TDE encryption ua haujlwm li cas?

TDE encrypts rhiab cov ntaub ntawv khaws cia hauv cov ntaub ntawv cov ntaub ntawv. Txhawm rau tiv thaiv tsis tau tso cai decryption, TDE khaws cov encryption cov yuam sij hauv kev ruaj ntseg module sab nraud rau hauv cov ntaub ntawv, hu ua keystore. Koj tuaj yeem teeb tsa Oracle Key Vault ua ib feem ntawm TDE kev siv.

Ib sab saum toj, TDE yog dab tsi thiab vim li cas peb siv nws? Transparent Data Encryption ( TDE ) tau qhia nyob rau hauv SQL Server 2008. Nws lub hom phiaj tseem ceeb yog los tiv thaiv cov ntaub ntawv los ntawm kev encrypting cov ntaub ntawv lub cev, ob qho tib si cov ntaub ntawv (mdf) thiab cov ntaub ntawv (ldf) (raws li tsis yog cov ntaub ntawv tiag tiag khaws cia hauv database). Tsis tas li ntawd, TempDB database yuav tau txais encrypted.

Kuj Paub, dab tsi yog encryption thaum so?

Encryption . Cov ntaub ntawv encryption , uas tiv thaiv cov ntaub ntawv visibility nyob rau hauv cov kev tshwm sim ntawm nws tsis tau tso cai nkag los yog tub sab nyiag, feem ntau yog siv los tiv thaiv cov ntaub ntawv nyob rau hauv lub zog thiab nce txhawb rau kev tiv thaiv cov ntaub ntawv ntawm so . Cov encryption ntawm cov ntaub ntawv ntawm so yuav tsum tsuas suav nrog muaj zog encryption txoj kev xws li AES lossis RSA.

Puas yog SQL cov ntaub ntawv encrypted?

Qhov xwm zoo yog tias Microsoft SQL ntawv Server los nruab nrog pob tshab cov ntaub ntawv encryption (TDE) thiab extensible key tswj (EKM) los ua encryption thiab kev tswj hwm qhov tseem ceeb siv tus thawj tswj hwm thib peb yooj yim dua li qhov qub.
