Finding ID Version Rule ID IA Controls Severity

Description
If the user is aware that a certificate is invalid, the user can opt not to proceed or, alternatively, is better prepared to identify suspicious behavior that indicates an IA incident is in progress. Failure to notify the user of this occurrence makes it more likely that an adversary can launch an attack from an untrusted system.
