This protocol anomaly detects multiple authentication failures within a short period of time between a unique pair of hosts. The IDP considers the following errors returned by the server as an indication of authentication failure (RFC-2251#4.1.10) - strongAuthRequired, inappropriateAuthentication, invalidCredentials, insufficientAccessRights. The number of login failures to trigger this attack can be configured in the Sensor Settings Rule base of your Security Policy.
Multiple login failures within a short period could indicate that a brute force password guessing attack is taking place or has taken place.
