Vulnerability discussion

If the gateway router is not a dedicated device for the OOBM network, several safeguards must be implemented for containment of management and production traffic boundaries. It is imperative that hosts from the managed network are not able to access the OOBM gateway rouiter.

Check content

Review the ACL or filters for the router’s receive path and verify that only traffic sourced from the management network is allowed to access the router. This would include both management and control plane traffic.

Fix text

Ensure that traffic from the managed network is not able to access the OOBM gateway router using either receive path or interface ingress ACLs.

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.
