US Patent 8161547 Monitoring traffic to provide enhanced network security

A communication system includes a traffic monitoring element that monitors network traffic between network components. The network traffic monitoring element monitors for security anomalies and, upon detecting a security anomaly, may respond appropriately. For example, the network traffic monitoring element may identify a security certificate communicated from a server application to a client application, determine the validity of the certificate, and disrupt further communications between the server application and the client application if the certificate is not valid.
