TDE (Transparent Data Encryption) is highly effective in preventing unauthorized access to data at rest, but its primary purpose is encryption rather than direct tamper prevention. TDE encrypts data files, backups, and logs, ensuring that even if physical storage is compromised, the data remains unreadable without the encryption key. However, TDE does not inherently detect or prevent data tampering during runtime.
For tamper detection and prevention, additional measures like database integrity checks, checksums, or digital signatures are needed. Some databases integrate TDE with auditing or logging features to track changes, but these are separate from TDE's core encryption functionality.
In cloud environments, Tencent Cloud provides TDE for databases like MySQL and SQL Server, ensuring data at rest is encrypted. For tamper prevention, Tencent Cloud also offers database audit services and data integrity solutions, such as COS (Cloud Object Storage) with versioning and checksum validation, to complement TDE's encryption.
