What’s the best practice for rotating TLS certificates?
Asked on Oct 02, 2025
Answer
Rotating TLS certificates is crucial for maintaining secure communications, and best practices involve automating the process to ensure certificates are updated before they expire.
Example Concept: Certificate rotation involves replacing an old TLS certificate with a new one before the old certificate expires. This process should be automated to minimize downtime and prevent expired certificates from being used. Automation tools like Certbot can be configured to renew certificates automatically, especially for Let's Encrypt certificates.
Additional Comment:
- Ensure your certificate authority (CA) supports automated renewal processes.
- Monitor certificate expiration dates and set alerts to avoid unexpected expirations.
- Test the new certificate in a staging environment before deploying it to production.
