The signature file is the heart of the IPS system. It is similar
to the Virus definition file on your PC’s Anti-Virus software.
IPS uses this file to match against packets coming into the
Router and performs actions accordingly. The RVS4000 is
shipped with a signature file containing 1000+ rules, which
cover the following categories: DDoS, Buffer Overflow,
Access Control, Scan, Trojan Horse, Misc., P2P, IM, Virus,
Worm, and Web Attacks.
Customers are encouraged to update their IPS signature
file regularly to prevent any new types of attacks on the
Internet.
