🔒 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
