🔒 Encryption is crucial for data security. Here are key guidelines to implement effectively:
1. Choose Strong Algorithms
- Use AES-256 for symmetric encryption (✅ Learn more)
- Prefer RSA-2048 or higher for asymmetric operations
- 📌 Avoid deprecated protocols like SSLv3 or RC4
2. Secure Key Management
- Store keys in hardware security modules (HSMs) whenever possible
- Rotate keys periodically (⏰ Recommended: every 90 days)
- 🔐 Use key derivation functions (e.g., PBKDF2, bcrypt)
3. Encrypt Data at Rest & in Transit
- 🔒 Full-disk encryption for servers and storage devices
- 🌐 TLS 1.3 for secure communications (🔗 See implementation guide)
- 🔒 Always encrypt sensitive data before storing
4. Implement Access Controls
- 🔐 Role-based access control (RBAC) for encrypted resources
- Use AES-GCM mode for authenticated encryption
- 🔒 Regularly audit key access permissions
5. Stay Updated with Standards
- Follow NIST guidelines for encryption practices
- 📌 Monitor cryptographic vulnerabilities (e.g., CVE-2023-20815)
- 🧠 Understand quantum computing threats to current encryption
