Vulnerability discussion

Taking an appropriate action based on local organizational incident handling procedures minimizes the impact of malicious code on the network.The ALG must be configured to block all detected malicious code. It is sometimes acceptable/necessary to generate a log event and then automatically delete the malicious code; however, for critical attacks or where forensic evidence is deemed necessary, the file should be quarantined for further investigation.The CA API Gateway must be configured to integrate with an ICAP-enabled Intrusion Detection System such as McAfee, Sophos, or Symantec. These systems must be configured in accordance with organizational requirements, which must include the deletion of malicious code once detected.

Check content

Open the CA API Gateway - Policy Manager and double-click any of the Registered Services that require the deletion of malicious code once detected. Verify the "Scan Using ICAP-Enabled Antivirus" Assertion is included in the policy. If it is not, check to see if it has been added to a Global Policy. If the Assertion is not present in either Global or Registered Services policy, this is a finding.

Fix text

Open the CA API Gateway - Policy Manager and double-click any of the Registered Services that did not have the "Scan Using ICAP-Enabled Antivirus" Assertion. Add the "Scan Using ICAP-Enabled Antivirus" Assertion, configure the parameters for the Assertion in accordance with organizational requirements, and click the "Save and Activate" button. If the organization requires that all Registered Services require the ability to delete malicious code upon detection, consider adding the "Scan Using ICAP-Enabled Antivirus" Assertion to a Global Policy to meet this requirement.

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.
