Vulnerability discussion

Without information about the outcome of events, security personnel cannot make an accurate assessment as to whether an attack was successful or if changes were made to the security state of the network. Event outcomes can include indicators of event success or failure and event-specific results (e.g., the security state of the network after the event occurred). As such, they also provide a means to measure the impact of an event and help authorized personnel to determine the appropriate response.

Check content

Review the SDN controller configuration to determine if the audit records will note the outcome (i.e. packet allowed, packet dropped, link down, etc.) the event that is being logged. If the SDN controller is not configured to produce audit records containing information to establish the outcome (i.e. packet allowed, packet dropped, link down, etc.) of the events, this is a finding.

Fix text

Configure the SDN controller to include the outcome (i.e. packet allowed, packet dropped, link down, etc.) of the event in the log records.

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.
