Let's briefly discuss these layers:

  • First layer: Wireless signals

In wireless networks, the continuous monitoring and managing of the RF spectrum within your environment helps to identify threats and makes you aware of its capabilities. You may want to invest in something like an IDS system or even in a wireless intrusion detection system (WIDS).
