Abstract
A multilayered intrusion detection system and method are disclosed. The method includes monitoring activity on a network and maintaining a registry of each host node address associated with a host node operable to perform host-based intrusion detection services. The method further includes comparing a destination address of the monitored network activity with at least one host node address in the registry. If an address of the network activity matches an address of a registered host node, the network activity is dismissed and allowed to proceed unencumbered to the registered host node. The network activity not destined for a registered host node has intrusion detection services performed on it. The network activity dismissed to the host node has intrusion detection services performed on it at the receiving host node.
