Abstract
A network security and surveillance system passively monitors and records the traffic present on a local area network, wide area network, or other type of computer network, without interrupting or otherwise interfering with the flow of the traffic. Raw data packets present on the network are continuously routed (with optional packet encryption) to a high-capacity data recorder to generate low-level recordings for archival purposes. The raw data packets are also optionally routed to one or more cyclic data recorders to generate temporary records that are used to automatically monitor the traffic in near-real-time. A set of analysis applications and other software routines allows authorized users to interactively analyze the low-level traffic recordings to evaluate network attacks, internal and external security breaches, network problems, and other types of network events.
