Minimize Wireless Signal Propagation

Wireless signals frequently propagate outside of organizational boundaries, which provide opportunities for adversaries to monitor or gain unauthorized access to the wireless network. [1] To minimize this threat, organizations should implement measures to detect, understand, and reduce unnecessary RF propagation. [2]

Techniques Addressed by Mitigation

Domain ID Name Use
ICS T0860 Wireless Compromise

Techniques can include (i) reducing transmission power on wireless signals, (ii) adjusting antenna gain to prevent extensions beyond organizational boundaries, and (iii) employing RF shielding techniques to block excessive signal propagation. [2]

ICS T0887 Wireless Sniffing

Reduce the range of RF communications to their intended operating range when possible. Propagation reduction methods may include (i) reducing transmission power on wireless signals, (ii) adjusting antenna gain to prevent extensions beyond organizational boundaries, and (iii) employing RF shielding techniques to block excessive signal propagation.
