The CA API Gateway must restrict or block harmful or suspicious communications traffic by controlling the flow of information between interconnected networks based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic.
An XCCDF Rule
Description
<VulnDiscussion>Information flow control regulates where information is allowed to travel within a network and between interconnected networks. Blocking or restricting detected harmful or suspicious communications between interconnected networks enforces approved authorizations for controlling the flow of traffic. This requirement applies to the flow of information between the CA API Gateway when used as a gateway or boundary device that allows traffic flow between interconnected networks of differing security policies. The CA API Gateway should be installed and configured to restrict or block information flows based on guidance in the Ports, Protocols, and Services Management (PPSM) regarding restrictions for boundary crossing for ports, protocols, and services. Information flow restrictions may be implemented based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic. The CA API Gateway policies securing the Registered Services should include rules to control the flow of information between systems and networks with policy filters (e.g., rules that parse the Request Message attributes and/or signatures) that restrict or block information system services; provide a packet-filtering capability based on header information; and/or perform message filtering based on message content.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Open the CA API Gateway - Policy Manager.
Double-click all Registered Services required to restrict or block harmful or suspicious traffic.
Add /update the policy with the appropriate Assertions and include the proper logic and flow based on the information derived from parsing the attributes of a message request to the API in accordance with organizational requirements.
