Abstract
A key validation service may automatically determine whether an unauthorized public key was used by a client to log into a host using client-based authentication. This may allow the service to detect that an attack has occurred to circumvent the certificate workflow (e.g., tampering with the host security configuration file or using a replica of a trusted certificate authority). The service may do so by comparing the public key that was used by a client to a list of authorized public keys (e.g., public keys that are trusted by the service). When an unauthorized public key is detected, the service may provide a notification.
