What is the main action in inventorying certificates during their lifecycle?

The main action in inventorying certificates during their lifecycle is to track certificates in use. This process involves keeping detailed records of all certificates that are issued, including their expiration dates, associated domains or services, and their status (active, revoked, etc.).

Tracking is essential for several reasons. First, it helps ensure that certificates are valid and up-to-date, contributing to the overall security posture of an organization. By maintaining an accurate inventory, organizations can plan for renewals well in advance of expiration dates, reducing the risk of service disruption.

Moreover, effective tracking allows for compliance with regulatory requirements and standards, as it provides proof of certificate management and usage. It also enables organizations to identify any unauthorized certificates that may pose security risks.

While renewing certificates, developing new certificates, and revoking expired certificates are all important actions in the management process, the activity of tracking is foundational to achieving effective lifecycle management of certificates. Without proper tracking, renewal and revocation efforts may not be timely or effective.
