Abstract
A method of monitoring a network is provided. The method includes receiving a packet of network traffic, determining a source IP address of the packet, consulting a database of source IP addresses, each source IP address having an associated probability of threat indicator (PTI) that indicates a probability of threat posed by the source IP address. The packet's source IP address' PTI is assigned to the packet as the packet's PTI, and one or more inspection checks are selected to be performed on the packet, wherein the selection of the inspection checks is a function of the packet's source IP address PTI. The method further includes performing the selected inspection checks, assigning treatment of the packet based on a result of the inspection checks performed, and adjusting the packet's source IP address' PTI or the packet's PTI based on the result of the one or more inspection checks performed.
