Adversaries may block access to Wi-Fi communications to prevent messages from reaching target systems and devices. Wi-Fi connections allow for communications between IT and OT systems and devices. Blocking Wi-Fi communications may also block command and reporting messages.^[1]

An adversary may block Wi-Fi communications by disabling network interfaces, Service Stop, conducting an Adversary-in-the-Middle attack and dropping the network traffic, or by jamming the Wi-Fi signal.
