Why is passive scanning recommended alongside wireless security technologies?

Passive scanning is recommended alongside wireless security technologies primarily because it helps identify rogue devices within a network. This method of scanning involves listening to the wireless signals without actively engaging with the access points or devices. By doing so, it can detect unauthorized or rogue devices that may be connected to the network, which could pose a significant security risk.

Rogue devices can be anything from unauthorized access points set up by attackers to devices that do not adhere to the organization's security policies. Passive scanning is beneficial in this context because it allows for the identification of these devices without alerting them or potentially exposing the network to further risks. By recognizing rogue devices in real-time, organizations can take corrective actions to secure their network, ensuring that only authorized devices are permitted access.

This focus on identifying unauthorized entities is crucial in maintaining the integrity and security of wireless networks, making passive scanning a key component of a comprehensive security strategy that supplements other wireless security technologies.
