AAA Services must be configured to place non-authenticated network access requests in the Unauthorized VLAN or the Guest VLAN with limited access.
Medium Severity
<VulnDiscussion>Devices having an IP address that do not pass authentication can be used to attack compliant devices if they share VLANs. When devices proceed into the NAC AAA (radius) functions they must originate in the Unauthorized VLAN by default. If the device fails authentication, it should be denied IP capability and movement to other dynamic VLANs used in the NAC process flow or moved to a VLAN that has limited capability such as a Guest VLAN with internet access, but without access to production assets.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
