Cisco Intrusion Prevention System Sensors are network devices that monitor network traffic in real time for suspicious activities and active network attacks. Sensors come in three physical models: dedicated, standalone network appliances; line-card modules running in certain Cisco Catalyst 6000 switches; and line-card modules running in certain Cisco IOS routers. The sensor analyzes network packets and flows to determine whether their contents suggest an attack against your network.
Management Center for IPS Sensors (IPS MC) manages configurations for up to 300 Cisco Intrusion Prevention System Sensors. You use a series of web-based screens to manage all aspects of sensor configuration. You can manage individual sensors, and you can manage groups of sensors that have a common configuration. The sensor configuration data resides in a database.
