Chapter 19 Signatures
To protect your company's network from malicious intrusions and attacks, the
CS-2001 provides alerts and blocking mechanisms based upon the inspection of
packets and the detection of anomaly traffic flows. Regardless of whether the attack
originated internally or externally, the device ensures that legitimate network traffic
remains secure and undisturbed.
To deal with different forms of attacks, three types of signatures are provided:
 Anomaly: Detects suspicious packets and anomaly flows based upon definitions
from the latest signature file version.
 Pre-defined: Detects suspicious packets and anomaly flows based upon
pre-defined definitions from the latest signature file version.
 Custom: Allows the IT administrator to define signatures based on specific
customizable criteria.
