Signature File Definition
A signature file is a package of network patterns, policies, and/or countermeasures developed for Cisco intrusion
detection and prevention system (IDS/IPS) products. This signature package, used by the IDS/IPS products,
enables the sensors to provide up-to-date protection for the evolving threat environment. These IDS/IPS devices
compare network traffic (packets and streams) against data patterns within the signature file library. This
comparison is used to detect and control unauthorized or malicious network traffic. Therefore, the signature file,
once installed on an IDS/IPS product, becomes the signature database used to detect suspicious behavior and to
provide protection against the latest vulnerabilities and exploits.
