Vulnerability discussion

Using standardized authentication protocols such as RADIUS, TACACS+, and Kerberos, an authentication server provides centralized and robust authentication services for the management of network components. In order to control access to the servers as well as monitor traffic to them, the authentication servers should only be connected to the management network.

Check content

If the AAA Service is not used to authenticate privileged users for device management, this is not applicable. Verify the AAA Service is configured to connect to the management network. Confirm the AAA Service is not dual-homed by physically inspecting the physical LAN connection. If the AAA Service is configured to connect to a non-management network, this is a finding.

Fix text

Configure the AAA Service used to authenticate privileged users for device management to connect to the management network.

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.
