What does the term "rogue devices" refer to in passive scanning?

The term "rogue devices" in the context of passive scanning refers specifically to unauthorized access points that have joined a network without proper authorization or oversight from the network administrators. These devices can pose significant security risks, as they may allow malicious users to gain access to sensitive information, bypass security controls, or exploit vulnerabilities within the network.

In passive scanning, the primary focus is on monitoring network traffic and other signals to detect the presence of devices without actively probing the network. This method helps identify rogue devices by listening for their signals or traffic patterns, allowing administrators to spot unauthorized devices that might be trying to connect to the network.

By identifying these rogue access points early, organizations can take appropriate measures, such as strengthening their network security policies, implementing stricter access control protocols, and improving overall network monitoring to prevent potential breaches or unauthorized access.
