ABSTRACT:
An intrusion-prevention server supporting a set of hosts comprises data filters and an engine which uses a set of encoded rules for assigning data filters to hosts according to metadata characterizing the hosts. Each data filter corresponds to at least one intrusion pattern from among a set of intrusion patterns and the data filters are continuously updated as intrusion patterns change. Metadata acquired from a host varies with a changing state of the host. Acquisition of metadata from each host is streamlined to reduce communications between the server and the hosts and to minimize processing effort for both the server and the hosts.
