TLS Security Best Practices
- Enable TLS 1.2 and 1.3, disable 1.0 and 1.1
- Configure proper cipher suite order by strength
- Implement HSTS with appropriate max-age and includeSubDomains
- Use certificates from trusted Certificate Authorities
- Implement proper certificate chain validation
- Set up automated certificate renewal and monitoring
- Configure CAA records to control certificate issuance
- Enable OCSP stapling for faster certificate validation
- Use modern AEAD ciphers for better security and speed
- Monitor certificate expiry dates proactively
How to improve TLS security
