Vulnerability discussion

Failing to automatically update malicious code protection mechanisms, including application software files, signature definitions, and vendor-provided rules, leaves the system vulnerable to exploitation by recently developed attack methods and programs. An automatic update process ensures this important task is performed without the need for SCA intervention.The IDPS is a key malicious code protection mechanism in the enclave infrastructure. To ensure this protection is responsive to changes in malicious code threats, IDPS components must be automatically updated, including anti-virus signatures, detection heuristics, vendor-provided rules, and vendor-provided signatures.If a DoD patch management server or update repository having the tested/verified updates is available for the device component, the components must be configured to automatically check this server/site for updates and install new updates.If a DoD server/site is not available, the component must be configured to automatically check a trusted vendor site for updates. A trusted vendor is either commonly used by DoD, specifically approved by DoD, the vendor from which the equipment was purchased, or approved by the local program's CCB.

Check content

To verify that automatic updates are configured: Go to Device >> Dynamic Updates If no entries for "Applications and Threats" are present, this is a finding. If the "Applications and Threats" entry states "Download Only", this is a finding.

Fix text

Go to Device >> Dynamic Updates Select "Check Now" at the bottom of the page to retrieve the latest signatures. To schedule automatic signature updates. Note: the steps provided below do not account for local change management policies. Go to Device >> Dynamic Updates Select the text to the right of "Schedule". In the "Applications and Threat Updates Schedule" Window; complete the required information. In the "Recurrence" field, select "Daily". In the "Time" field, enter the time at which you want the device to check for updates. For the "Action", select "Download and Install". Select "OK". Commit changes by selecting "Commit" in the upper-right corner of the screen. Select "OK" when the confirmation dialog appears.

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.
