Why might data exchanges between a WLC and APs occur in plain-text instead of being encrypted?

• A. The WLC does not support encryption
• B. DTLS is disabled for the data channel by default
• C. CAPWAP does not support encryption
• D. The APs are not configured properly

Answer: (B)

Data exchanges between a Wireless LAN Controller (WLC) and Access Points (APs) may occur in plain-text primarily due to the default configuration settings relating to Datagram Transport Layer Security (DTLS). When DTLS is disabled for the control and data channels established by the Control And Provisioning of Wireless Access Points (CAPWAP) protocol, the data exchanged may not be encrypted, leading to potential security vulnerabilities. In typical deployments, securing communication between WLCs and APs is crucial for protecting sensitive data. DTLS provides encryption for these exchanges, ensuring that if the feature is enabled, the communication remains confidential and less susceptible to interception. However, if this security feature is turned off—whether due to administrative settings or lack of configuration—then the data flights initiated between the WLC and APs can occur without encryption, resulting in plain-text exchanges. Understanding this context highlights the critical nature of the proper configuration of the WLC and the need to ensure that encryption protocols like DTLS are enabled to safeguard data communications.
