SSL/TLS protocols are critical for securing data transmission over the internet. Below is a concise guide for developers and administrators:

Key Concepts 🔍

  • SSL/TLS Handshake

    TLS Handshake Process
    Establishes encrypted communication between client and server. [Learn more about the handshake process](/en/docs/ssl_tls_handshake)

  • Certificates
    Use X.509 certificates to authenticate servers.

    SSL/TLS Certificate
    [View certificate configuration examples](/en/docs/ssl_tls_configuration_guide)

  • Cipher Suites
    Select strong ciphers like TLS_AES_256_GCM_SHA384 for encryption.
    Avoid deprecated protocols such as SSLv3 🚫

Best Practices ✅

  1. Enable HSTS header for HTTP Strict Transport Security
  2. Use OCSP stapling to reduce latency
  3. Regularly update TLS versions (prefer TLS 1.3)
  4. Implement perfect forward secrecy (PFS)

Security Risks ⚠️

  • POODLE attack: Vulnerability in SSLv3
  • BEAST attack: Targeted TLS 1.0
  • Heartbleed: OpenSSL library flaw
  • Man-in-the-middle (MITM): Mitigate with certificate pinning
