Abstract
A network security system includes a network interface configured to connect to a public wide area network and a first malicious activity detection subsystem configured to extract from textual sources on the network different threat levels in a first threat category for addresses on the wide area network. One or more further malicious activity detection subsystems are configured to extract from textual sources on the network different threat levels in one or more further threat categories. A weighting subsystem is configured to provide weighted threat levels for addresses on the wide area network for the first and further malicious activity detection subsystems. A scoring subsystem is responsive to the weighting subsystem to derive an aggregated, weighted threat score for each of the network addresses. An address proximity engine can determine a measure of logical proximity of network addresses independently of any measure of physical proximity between them.
