How does the WLC perform wireless security management?

The choice of using external RADIUS servers for client authentication is foundational in wireless security management. When a Wireless LAN Controller (WLC) is involved, it typically serves as the centralized point of control for managing security policies across all access points associated with it. By integrating with RADIUS servers, the WLC can validate user credentials and authorize access to the network. This process enhances security by ensuring that only authenticated users are allowed to connect, thereby mitigating risks associated with unauthorized access.

In addition, the WLC can support multiple authentication methods, such as PEAP, EAP-TLS, or EAP-FAST, all of which can authenticate users against the RADIUS server for a dynamic and secure management of wireless clients. The engagement with external RADIUS servers allows for better scalability and management of user credentials, particularly in larger enterprise environments.

The other options, while they may involve aspects of network security or client management, do not exemplify the primary function of the WLC in achieving robust wireless security. For example, simply blocking all incoming traffic would lead to service disruption and is not a practical security management strategy. Encrypting all wireless communications is critical for data security but relies on the initial authentication process to govern who can join the network. Lastly, configuring
