What is an important factor to determine during a WLAN site survey regarding security?

Determining the potential for unauthorized network access is a crucial factor during a WLAN site survey regarding security. This involves assessing where and how unauthorized users might gain access to the network, which can include identifying vulnerabilities in signal coverage and areas where the network might be exposed to external attacks. A thorough understanding of where the wireless signals extend, beyond the intended coverage area, helps in strategizing how to fortify the network against potential breaches.

While other aspects of security, such as placement of surveillance cameras, are important for overall safety and monitoring, they do not directly address the key concern of network access vulnerabilities. Similarly, user training materials and equipment procurement checklists contribute to an effective network operation and maintenance but do not specifically focus on the risks of unauthorized access to the WLAN. Thus, evaluating the potential for unauthorized network access is essential to develop a secure wireless network environment.
