Cisco WCS Security Index

C.

The Cisco WCS (Wireless Control System) is a network management tool used to monitor, configure, and troubleshoot wireless networks. The security index is a feature in the Cisco WCS that provides an overall score of the network's security posture. The security index is based on several factors, including the number of rogue access points and clients detected, the number of security threats detected, and the network's configuration parameters.

Option A states that the security index will display red (high threat level) when the managed WLAN detects multiple rogues and attack signatures. This statement is partially correct. The security index considers the number of rogues and security threats detected, but the index's color coding may vary depending on the severity of the detected threats.

Option B states that the security index is a weighted scale of WLAN security ranging from 0 least risk (secure) to 100 high risk (unsecure). This statement is also incorrect. The security index ranges from 0 to 10, and the higher the score, the more secure the network is considered.

Option C states that the security index uses device configuration parameters to assign a weighted value of network security. This statement is partially correct. The security index considers the configuration parameters of the wireless devices in the network and assigns a weighted value to them.

Option D states that the security index of the Cisco WCS managed network is the average of all controller and Cisco MSE scores. This statement is incorrect. The security index is calculated based on various factors, including the number of rogues and security threats detected, the network's configuration parameters, and other security-related events.

In conclusion, option C is the most accurate statement regarding the Cisco WCS security index. The security index considers the configuration parameters of the wireless devices in the network and assigns a weighted value to them.
