Identify and Remove Expired IAM Server Certificates

Overview

Identify and remove expired IAM server certificates from your AWS accounts to reduce security risk and eliminate unused IAM artifacts. This plan walks through discovering all IAM server certificates, determining which ones are expired and safe to remove, guiding you through a review and approval step, deleting the approved certificates, and finally validating that no expired certificates remain.

The workflow starts by building a complete inventory of IAM server certificates and their expiration status across in-scope accounts. It then highlights expired certificates and those past a defined age threshold, presents them for your review and approval, performs the cleanup of the certificates you approve for deletion, and concludes with a validation phase that confirms the cleanup is complete and documented.

Execution Details

Assessment

1. Enumerate IAM server certificates and capture key attributes

First, the plan focuses on discovery and documentation:

• Determine which AWS accounts are in scope for IAM server certificate cleanup.
• Enumerate all IAM server certificates in each in-scope account.
• For each certificate, capture key attributes such as name, ARN, upload date, expiration date, and path.
• Infer a basic status (for example, valid vs. expired) based on expiration and any available metadata.
• Record any tags (such as Environment, Application, or Owner) to help with later analysis and stakeholder review.
• Store this complete inventory in a structured format (such as a table or dataset) for subsequent filtering and user review.

2. Identify expired and cleanup-candidate certificates

Next, the inventory is analyzed to isolate certificates that should be considered for removal:

• Retrieve the structured inventory of IAM server certificates from the previous task.
• Define a cutoff date or age threshold to determine which expired certificates are cleanup candidates (for example, expired as of today or older than a specified number of days).
• Compare each certificate’s expiration date to the current date and the defined cutoff.
• Flag all expired certificates, and from that set, highlight those that are older than the cutoff as primary deletion candidates.
• Produce a consolidated list of expired and candidate-for-deletion certificates, including name, ARN, expiration date, age past expiration, path, and any relevant tags.
• Store this candidate list in a structured format to support user review and final decision-making.

3. Guide user review and approval for deletion

The plan then involves you and other stakeholders in determining what can be safely removed:

• Present the list of expired (and age-threshold) certificates, along with their key details and tags, to give context on possible usage and ownership.
• Guide you through assessing historical or potential usage, helping you consider factors such as application dependencies, audit needs, or rollback scenarios.
• Support classification of each certificate as: approved for deletion, to be retained, or requiring further investigation.
• Capture reasons for retaining or further investigating specific certificates (for example, awaiting confirmation from an application owner).
• Confirm, for certificates approved for deletion, that there are no known remaining dependencies.
• Produce a finalized, user-approved deletion list including certificate name, ARN, account, and review notes, stored for use in the configuration phase.

Configuration

4. Delete user-approved expired IAM server certificates

With a vetted list in hand, the plan carries out the actual cleanup:

• Retrieve the user-approved list of expired certificates selected for deletion.
• Immediately before deletion, revalidate each certificate to ensure it still exists and matches the expected identity (name/ARN).
• Initiate deletion of each approved certificate from IAM.
• Log any certificates that cannot be deleted, including detailed error information for later follow-up.
• After deletion, re-enumerate IAM server certificates in each affected account to confirm that the targeted certificates no longer appear.
• Generate a configuration summary that clearly states which certificates were successfully deleted and which, if any, remain due to errors or exceptions, ensuring only user-approved expired certificates were modified.

Validation

5. Confirm no expired IAM server certificates remain

To close the loop, the plan validates the final state and documents any exceptions:

• Re-enumerate IAM server certificates across all in-scope accounts after cleanup is complete.
• Check each remaining certificate’s expiration date to confirm that none are already expired.
• Compare the post-cleanup inventory against the pre-cleanup view to verify that all previously approved expired certificates have been removed.
• Document any remaining expired certificates (if discovered) along with their name, ARN, account, and the reason they were not removed (for example, deletion failures or newly discovered certificates).
• Create a follow-up remediation list if any expired certificates remain, or explicitly document that none remain.
• Inform stakeholders (for example, via an existing ticket, change record, or similar channel) that validation is complete and provide a clear statement of the final status and any outstanding exceptions.
