SECURE ENTERPRISE NETWORK

What is proposed is a method of implementing a security system (Packet Sentry) addressing the internal security problem of enterprises having a generalized approach for inferential determination and enforcement of network policy with directory service based group correlation with transparent authentication of the connected customer and the policy enforcement inside the network. The security system enables the network to analyze and enforce policy using any bit or bits in a stream or a packet, conduct Flow Vector analysis on the data traffic, provide Application Monitoring, Normalization and user authentication validation. The system enables the network to implement Group relationship Analysis and correlation using combination of Network inferences and Directory service data resulting in generation of Group norms using statistically significant relationships. These will provide a more secure enterprise environment where data security levels can be enforced and the usage monitored effectively in the infrastructure.
