Vulnerability discussion

Unrestricted traffic may contain malicious traffic that poses a threat to an enclave or to other connected networks. Additionally, unrestricted traffic may transit a network, which uses bandwidth and other resources.Access control policies and access control lists implemented on devices that control the flow of network traffic (e.g., application-level firewalls and Web content filters), ensure the flow of traffic is only allowed from authorized sources to authorized destinations. Networks with different levels of trust (e.g., the Internet or CDS) must be kept separate.CA API Gateway must use services, policy, and iptable configurations to enforce flows only to/from authorized sources and destinations.

Check content

Open the CA API Gateway - Policy Manager, select "Tasks" from the main menu, and chose "Manage Listen Ports". Click the "Manage Firewall Rules" button and verify the proper Firewall Rules have been configured in accordance with organizational requirements for routing communications between authorized sources and destinations. Additionally, double-click each of the Registered Services and verify their policies have the proper logic to route the communications traffic to and from authorized sources and destinations. If either the firewall rules or the policy logic is not configured properly, this is a finding.

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.
