Description
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
| Name | Use |
|---|---|
| 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 |
| 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. 2 |
