What is the primary function of the Cisco Intrusion Detection System Services Module (IDSM)?

The Cisco Intrusion Detection System Services Module (IDSM) is primarily designed to serve as an intrusion detection and prevention solution. Its main function is to monitor network traffic for suspicious activity and potential threats, allowing organizations to detect and respond to intrusions in real-time. The IDSM analyzes packet data traversing the network and can take proactive measures to prevent unauthorized access or attacks, making it a crucial component for maintaining network security.

The distinct capability of the IDSM differentiates it from other network components such as firewalls, which focus primarily on controlling traffic based on rules rather than identifying intrusions. While it does offer prevention capabilities, its core mission revolves around identifying and responding to threats. This functionality is essential for organizations looking to safeguard their networks against malicious activities.
