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
- Update server software to latest stable version
- Configure SSL/TLS settings in web server (Apache, Nginx, IIS)
- Use security configuration generators (Mozilla SSL Config Generator)
- Test configuration with multiple TLS testing tools
- Obtain certificates from reputable CAs (Let's Encrypt, DigiCert)
- Implement automated certificate renewal
- Add CAA records to control certificate issuance
- Monitor certificate expiry dates proactively
- Set up automated certificate expiry monitoring
- Configure security monitoring and alerting
- Regular TLS configuration reviews and testing
