Abstract:
A method of providing access control to resources of a network comprising steps of:monitoring network traffic, including receiving data packets transmitted to and from nodes of said network such that receptions of said data packets are non-intrusive with respect to traffic flow of said network;with respect to individual node-to-node transmissions within said network, assembling pluralities of said received data packets specific to said individual node-to-node transmissions, thereby forming an assembled multi-packet communication for each of said node-to-node transmissionbased upon said assembled multi-packet communications, identifying source nodes and destination nodes and contextual information for said individual node-to-node transmissions; andapplying access rules to said assembled multi-packet communications in determinations of whether said individual node-to-node transmissions are restricted transmissions, including basing said determinations on said identifying said source and destination nodes and said contextual information.
