Vulnerability discussion

If the access point or its supporting authentication server is placed in front of the perimeter firewall, then it has no firewall protection against an attack. If the access point or its supporting authentication server is placed behind the perimeter firewall (on the internal network), then any breach of these devices could lead to attacks on other DoD information systems.

Check content

Have the SA show how the guest WLAN is physically connected to the firewall or supporting switch and how it is logically connected through firewall or switch configuration settings. Verify the equipment is connected via a separate WLAN or logical segmentation of the host WLAN (e.g., separate service set identifier (SSID) and virtual LAN). If a guest WLAN is set up as a separate WLAN from the DoD network or not set up as a logical segmentation from the DoD network or DoD WLAN, this is a finding.

Fix text

Reconfigure physical and logical connections as needed so the Internet-only WLAN infrastructure resides in a dedicated subnet off the perimeter firewall.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
