Wireless access points and bridges must be placed in dedicated subnets outside the enclave's perimeter.
Medium Severity
<VulnDiscussion>If an adversary is able to compromise an access point or controller that is directly connected to an enclave network, the adversary can easily surveil and attack other devices from that beachhead. A defense-in-depth approach requires an additional layer of protection between the WLAN and the enclave network. This is particularly important for wireless networks, which may be vulnerable to attack from outside the physical perimeter of the facility or base given the inherent nature of radio communications to penetrate walls, fences, and other physical boundaries. Wireless access points and bridges must not be directly connected to the enclave network. A network device must separate wireless access from other elements of the enclave network. Sites must also comply with the Network Infrastructure STIG configuration requirements for DMZ, VLAN, and VPN configurations, as applicable. Examples of acceptable architectures include placing access points or controllers in a screened subnet (e.g., DMZ separating intranet and wireless network) or dedicated virtual LAN (VLAN) with ACLs.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
