This protocol anomaly detects multiple login failures within a short period of time between a unique pair of hosts. This typically indicates either a user or a script repeatedly trying to login to a server in order to guess the username and/or the password. The number of such login failures can be configured in the Sensor Settings Rulebase of the 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.
