Current firewalls and intrusion detection systems are generally designed to protect a single gateway in order to provide protection for machines residing behind the gateway on an internal network. When considering a network incorporating multiple gateways across a range of IP addresses exposed to the Internet, interesting data can be gathered with regard to the types of scans occurring across these gateways from the outside. The validity of using a central server to amalgamate, reduce and analyse the log files of each gateway is investigated in order to examine the activities of the scans across multiple gateways and port numbers. The results from this analysis can then be used to act against an attack through
heuristic driven rule creation.
