A graphical user interface for constructing rules to run on an intrusion detection system is described. The user interface includes a field that specifies a first set of nodes on a network by Host-Group, a field that specifies a second set of nodes on a network by Host-Group and a field which determines whether to interpret the first and second host-group fields as Client, server, source, destination or any of these.

Rule based alerting in anomaly detection

A graphical user interface for an intrusion detection system is described. The graphical user interface includes a field that depicts a summary of anomalies identified as part of a event that is detected in a network, the summary indicating event severity details of the event and an alert action region including a control to permit a user to snooze future alerts related to the event in the summary for a period of time.

Feedback mechanism to minimize false assertions of a network intrusion

A new service detection process in a network retrieves a baseline list of port protocols used by a entity being tracked. The baseline value is determined over a baseline period. A current list of port protocols for the entity being tracked is also retrieved and is compared to determine whether there is a difference in the port protocols, by having a protocol that was in a current list but was not in the baseline list. If there is a difference the process indicates a new service involving the tracked entity.

Service detection

An arrangement is disposed in a network. The arrangement includes a device that is logically disposed adjacent logically nearby routers having a first type of probe that are disposed to sample traffic, and that is has second type of probe that is disposed in-line during an attack by modifying router tables on the nearby routers.
