Does your organization implement network monitoring controls to detect and alert on unauthorized endpoint connections to both wired and wireless networks?
Explanation
Network monitoring for unauthorized endpoints is essential for detecting potential security breaches, rogue devices, and policy violations before they can cause harm. This includes monitoring both wired connections (like unauthorized computers or servers) and wireless connections (like unauthorized mobile devices or access points) that could be used to bypass security controls or exfiltrate data.
Evidence could include screenshots of network access control (NAC) systems, logs from network monitoring tools showing detection of unauthorized devices, documentation of alerting procedures when unauthorized connections are detected, or network diagrams showing placement of monitoring solutions.
