Impact of Security Policy for Credential Renewal on Availability

Policy: The developed policy for credential renewal and revocation will have an impact on availability. If an in-use credential is revoked/deprecated incorrectly, then information exchange will not be able to be achieved, thus impacting availability. Thus, policy development must be particularly careful in only revoking the credentials for appropriate reasons.

However, the actual revocation, based upon stolen or compromised credentials will have an impact on availability. Thus the time required to renew, create, or deploy new credentials needs to be factored into the availability calculation. For further discussion see credential renewal.
