High-speed adaptive structure of elementary firewall modules

摘要

A communications security system has been described. The security system in the form of a firewall is made up of a plurality of communicatively coupled sets of modules in a matrix configuration. The modules may be implemented in hardware and software in order to rely on the advantages of each technology. Data packets are typically coupled to an ingress side of the firewall where policy rules having the highest importance are checked first. The result is a high speed system having carrier class availability.
