The Common Content Inspection (CCI) standard, like SAM, is an API intended for additionally checking the traffic processed by the intrusion detection system sensor or by the firewall. Such checks might include detection of attack signatures, viruses, malicious mobile code, forbidden URLs, etc. The draft of the CCI interface (as well as all related documents that were not widely adopted, but still illustrate the direction of research and development) are available at the following address: http://www.stardust.com/cciapi/.
