Vulnerability discussion

Remote access devices (such as those providing remote access to network devices and information systems) that lack automated capabilities increase risk and make remote user access management difficult at best.Remote access is access to DoD non-public information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network. Automated monitoring of remote access sessions allows organizations to detect cyber attacks and also ensure ongoing compliance with remote access policies by auditing connection activities of remote access capabilities from a variety of information system components (e.g., servers, workstations, notebook computers, smart phones, and tablets).

Check content

Review the firewall configuration statements used to create a group policy with filtering rules for wireless clients accessing the network using a wireless access point. Verify both ingress and egress traffic on this interface is subject to the remote access policy and filtering rules required by the organization. If the firewall is used to filter traffic from the wireless access points but is not configured with filtering rules that apply to the monitoring of wireless access traffic, this is a finding.

Fix text

Configure a group policy for wireless clients and apply to the interface that is connected to allow ingress and egress to the wireless access points.
