Database Encryption
Database encryption is the process of converting data stored in a database into a ciphertext (encrypted form) to prevent unauthorized access or viewing of sensitive information. It involves applying encryption algorithms to data before storing it in the database and decrypting it when needed.
There are two main types of database encryption:
- Transparent Data Encryption (TDE): TDE encrypts the entire database or specific columns within a database without requiring changes to the application code. It operates at the storage layer, encrypting data as it is written to disk and decrypting it as it is read from disk. TDE protects data at rest, mitigating the risk of unauthorized access to data files or backups.
- Column-level Encryption: Column-level encryption selectively encrypts individual columns containing sensitive data within a database table. This allows organizations to apply encryption only to specific data fields rather than encrypting the entire database. Column-level encryption provides granular control over data protection and allows different encryption keys to be used for different columns.
Database encryption helps organizations comply with regulatory requirements and protect sensitive information from unauthorized access, both from external threats and insider attacks. It enhances data security by ensuring that even if an attacker gains access to the underlying database files, the data remains encrypted and unreadable without the appropriate decryption keys.
