TLS/SSL Deep Dive

Summary

Going beyond Phase 2's introduction — the full TLS handshake process, cipher suite negotiation, and common misconfigurations (weak ciphers, expired certificates) that create real vulnerabilities.

• 1Use a free tool (like SSL Labs) to scan a real website's TLS configuration for weaknesses.
• 2Learn what a downgrade attack is and why disabling old TLS versions matters.
• 3Understand certificate pinning as an advanced defense against certain man-in-the-middle attacks.
