Credential Rotation

Overview

Credential rotation limits the useful lifetime of a compromised password, key, token, certificate, or secret. The process issues a replacement, distributes it securely, migrates dependent systems, verifies successful use, and revokes the old credential.

Rotation may be scheduled or triggered by exposure, role change, cryptographic policy, vendor requirements, or incident response. Poor coordination can create outages, while long overlap periods leave the original credential available to an attacker.

Mature systems automate inventory, versioning, secure delivery, usage monitoring, and retirement. Emergency rotation plans should cover offline devices, third parties, backups, active sessions, and downstream credentials derived from or accessible through the compromised secret. Rollback procedures should not silently reactivate exposed material.

For Credential Rotation, teams should measure unnecessary friction, exclusion, delay, privacy intrusion, failed recovery, and inconsistent treatment while preserving the safeguards needed for material identity and access exposure.

Credential Rotation is a security mechanism or control discipline that replaces an existing secret or cryptographic credential with a new one and retires the previous version safely. Rotation reduces exposure only when dependencies migrate successfully and the previous credential, sessions, and related access are actually invalidated.

For Credential Rotation, the trust decision should establish a security mechanism or control discipline that replaces an existing secret or cryptographic credential with a new one and retires the previous version safely and bind the result to the requested action and protected resource. Teams should test issuance, storage, validation, expiry, revocation, recovery, and privileged override for security mechanism, rather than checking only a successful request. Logs concerning the Credential Rotation context and security mechanism should support investigation without exposing reusable secrets or unnecessary personal data.
