Tiv thaiv cov no cov ntaub ntawv cov ntaub ntawv, Oracle Database muab Transparent Data Encryption (TDE). TDE encrypts rhiab heev cov ntaub ntawv khaws cia rau hauv cov ntaub ntawv cov ntaub ntawv. Txhawm rau tiv thaiv kev decryption tsis raug cai, TDE khw muag khoom encryption cov yuam sij hauv kev ruaj ntseg module sab nraud rau hauv cov ntaub ntawv, hu ua keystore.

Ib yam li ntawd, Oracle Encryption Wallet yog dab tsi?

Tus tswv encryption qhov tseem ceeb yog khaws cia rau hauv lub Oracle hnab nyiaj , thiab yog siv los tiv thaiv kab encryption yuam sij. Los ntawm lub neej ntawd, tus tswv encryption tus yuam sij yog qhov yuam sij random tsim los ntawm cov ntaub ntawv pob tshab encryption . Nws tseem tuaj yeem yog khub tseem ceeb uas twb muaj lawm los ntawm PKI daim ntawv pov thawj tsim rau encryption.

Qhov thib ob, TDE encryption ua haujlwm li cas? Encrypting SQL Server: Transparent Data Encryption ( TDE ) Transparent Data Encryption ( TDE ) encrypts cov ntaub ntawv nyob rau hauv lub cev cov ntaub ntawv ntawm lub database, 'cov ntaub ntawv ntawm so'. Yog tsis muaj tus original encryption daim ntawv pov thawj thiab tus yuam sij tus tswv, cov ntaub ntawv tsis tuaj yeem nyeem tau thaum lub tsav nkag los yog lub cev tawm raug nyiag lawm.

Ib yam li ntawd, koj tuaj yeem nug, Transparent Data Encryption hauv SQL Server yog dab tsi?

Transparent Data Encryption (TDE) encrypts SQL Server , Azure SQL ntawv Database, thiab Azure Synapse Analytics ( SQL ntawv DW) cov ntaub ntawv cov ntaub ntawv, hu ua encrypting cov ntaub ntawv thaum so. Ib qho kev daws teeb meem yog encryption qhov rhiab cov ntaub ntawv hauv database thiab tiv thaiv cov yuam sij uas siv los encryption tus cov ntaub ntawv nrog daim ntawv pov thawj.

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.
