Discussion

It is possible that a disabled port that is assigned to a user or management VLAN becomes enabled by accident or by an attacker and as a result gains access to that VLAN as a member.

Fix Text

Assign all switch ports not in use to an inactive VLAN. Note: Switch ports configured for 802.1x are exempt from this requirement.

Check Content

Review the switch configurations and examine all access switch ports. Each access switch port not in use should have membership to an inactive VLAN that is not used for any purpose and is not allowed on any trunk links. If there are any access switch ports not in use and not in an inactive VLAN, this is a finding. Note: Switch ports configured for 802.1x are exempt from this requirement.
