Transparent Data Encryption (TDE)
SurePassID Universal MFA uses TDE with AES 256 to encrypt database files and protect all data at rest.
Definition
Transparent Data Encryption (TDE) is a technology employed by Microsoft, IBM, and Oracle to encrypt databases at the file level. TDE encrypts databases both on the hard drive and on any backup media. TDE relies on a cipher, either AES or 3DES.
TDE is typically employed to achieve compliance with regulatory regimes such as PCI DSS, which require the protection of data at rest.
How SurePassID works with TDE
SurePassID Universal MFA uses Microsoft SQL Server as its database. TDE is combined with military-grade AES 256 encryption to ensure that all data at rest is maximally protected, no matter where it is stored or replicated. This achieves compliance with PCI DSS, NIST 800-111, and other cyber security requirements.
