Definition:Encryption
Encryption is the process of encoding plain text information into unreadable ciphertext using mathematical cryptographic keys.
Detailed Technical Explanation
Business Perspective
Encryption ensures corporate data remains confidential even if database hardware or network traffic is intercepted.
Technical Perspective
Requires storing cryptographic KMS keys in dedicated secret stores outside database application code.
Real-World Example
Encrypting sensitive health records in PostgreSQL so direct database file reads reveal only ciphertext.
Common Architectural Mistakes
- ✗Hardcoding Encryption Keys: Embedding secret cryptographic keys directly inside Git source code repositories.
