Vulnerability discussion

Without auditing the enforcement of access restrictions against changes to any application within the SDN framework, it will be difficult to identify attempted attacks and an audit trail will not be available for forensic investigation for after-the-fact actions. Enforcement actions are the methods or mechanisms used to prevent unauthorized changes to configuration settings. Enforcement action methods may be as simple as denying access to a file based on the application of file permissions (access restriction). Audit items may consist of lists of actions blocked by access restrictions or changes identified after the fact.

Check content

Review the SDN controller configuration to determine if it is configured to audit enforcement actions used to restrict access associated with changes to any application. If the SDN controller is not configured to audit the enforcement actions used to restrict access associated with changes to any application within the SDN framework, this is a finding.

Fix text

Configure the SDN controller to audit enforcement actions used to restrict access associated with changes to any application.

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.
