The production VLAN assigned from the AAA server contains IP segments not intended for untrusted resources.

From Network Devices Security Technical Implementation Guide

SV-20099r1_rule The production VLAN assigned from the AAA server contains IP segments not intended for untrusted resources.

Vulnerability discussion

When policy assessment and remediation have been implemented and the advanced AAA server dynamic VLAN is mis-configured, logical separation of the production VLAN may not be assured.Non-trusted resources are resources that are not authenticated in a NAC solution implementing only the authentication component of NAC. Non-trusted resources could become resources that have been authenticated but have not had a successful policy assessment when the automated policy assessment component has been implemented.

Check content

Review the AAA server configuration. Have the SA display the policy groups. Have the SA display the vlan configuration. VLANs will be defined under Tunnel-Pvt-Group-ID with a tunnel type of VLAN. The dynamic VLAN definitions will have a IP pool assignment. Ensure the Production VLAN does not share the same AAA IP pool . Then verify the subnets used in other pools are not the same as the production.

Fix text

Build different IP pools. Use different IP subnets for each pool.
