Introduction

In this tutorial, we will address the issue of expiring TLS certificates within the Infinity platform. Proper management of TLS certificates is crucial for maintaining secure communications in your applications. This guide will walk you through diagnosing and troubleshooting TLS certificate alarms effectively.

Step 1: Identify the Expiring Certificate

• Open the Infinity Diagnostics interface.
• Navigate to the "Certificates" section.
• Look for any certificates marked with an expiration warning or alarm.
• Note the details of the certificates, including their expiration dates and associated services.

Step 2: Verify Certificate Details

• For each expiring certificate, check the following:
  • Common Name (CN): Ensure it matches the intended domain.
  • Validity Period: Confirm the expiration date and time.
  • Issuer: Verify the certificate authority that issued the certificate.
• Document any discrepancies or issues that may require attention.

Step 3: Generate a New Certificate

• If a certificate is nearing expiration, generate a new one by following these steps:
  • Access your certificate management tool or interface.
  • Select the option to create a new certificate.
  • Fill in the required fields:
    • Common Name
    • Key Size
    • Validity Period
  • Save the new certificate once created.

Step 4: Install the New Certificate

• Once the new certificate is generated, install it on the relevant servers or services:
  • Access the server or service where the certificate is to be installed.
  • Upload the new certificate file.
  • Configure the service to use the new certificate.
• Restart the service if necessary to apply changes.

Step 5: Verify Installation

• After installation, verify that the new certificate is properly configured:
  • Return to the Infinity Diagnostics interface.
  • Check the Certificates section again to confirm there are no remaining alarms.
  • Test the service to ensure it is functioning correctly with the new certificate.

Step 6: Set Up Monitoring and Alerts

• To prevent future issues with expiring certificates, set up monitoring:
  • Use tools to automatically check certificate expiration dates.
  • Configure alerts to notify you a few weeks before a certificate expires.
• Regularly review the certificate status to maintain secure operations.

Conclusion

Dealing with expiring TLS certificates is vital for maintaining the security of your applications. By following these steps, you can effectively troubleshoot and manage TLS certificate alarms. Remember to implement monitoring practices to stay ahead of future expirations. For ongoing management, consider periodic reviews of all certificates in your environment.
