SSL Security Best Practices
Automate Renewals
Forgotten certificates cause downtime. Use Let's Encrypt or professional monitoring to automate the renewal process.
Use Strong Protocols
Always prefer TLS 1.3 or 1.2. Disable older, vulnerable protocols like SSL 3.0, TLS 1.0, and TLS 1.1 on your server.
Monitor Transparency
Keep an eye on Certificate Transparency (CT) logs to ensure no unauthorized certificates are issued for your domain.
