Vulnerability discussion

Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. In order to compile an accurate risk assessment and provide forensic analysis, security personnel need to know the source (i.e. service, function, node name, IP address, etc.) of the event.

Check content

Review the SDN controller configuration to determine if the audit records will note the source (i.e. flow, API, IP address, etc.) the event that is being logged. If the SDN controller is not configured to produce audit records containing information to establish the source (i.e. flow, API, IP address, etc.) of the events, this is a finding.

Fix text

Configure the SDN controller to include the source (i.e. flow, API, IP address, 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.
