An appropriate WMAN coverage area must be reasonably sized and constrained to the areas intended for WMAN signals.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-18601	WIR0310	SV-20152r1_rule	ECWN-1	Low

Description
Wireless signals could be intercepted more easily by an adversary if the coverage area is not appropriately sized. If an adversary is able to intercept wireless signals, it is possible to obtain information about the location and intensity of DoD operations. If DoD data is not encrypted in transit, then the adversary will be able to capture it.

NOTE: This check should only be reviewed during the initial system Certification and Accreditation (C&A). Review the site SSP/SSAA and other DIACAP documentation. Verify an appropriate WMAN coverage area was determined during system design or the DIACAP. Compare the actual radio coverage of WMAN system with the intended coverage area map. Mark as a finding if the actual usable radio coverage in any direction is 10% greater (or more) than shown on the intended coverage area map.

Fix Text (F-34150r1_fix)
Implement a solution to constrain signals to areas in which they are intended to be received. Potential technical actions include using directional antennas or changing radio transmission power. If the coverage map does not reflect the operational requirement, it may be updated so that the current system is in compliance.
