Abstract

This is a system and method for network surveillance and detection of attempted intrusions, or intrusions, into the network and into computers connected to the network. The System functions are: (A) intrusion detection monitoring, (B) real-time alert, (C) logging of potential unauthorized activity, and (D) incident progress analysis and reporting. Upon detection of any attempts to intrude, the System will initiate a log of all activity between the computer elements involved and send an alert to a monitoring console. When a log is initiated, the network continues to be monitored by a primary surveillance system. A secondary monitoring process is started which interrogates the activity log in real-time and sends additional alerts reporting the progress of the suspected intruder.
