Vulnerability discussion

Without establishing where events occurred, 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, it is essential for security personnel to know where (e.g., interface, node, source IP, etc.) events occurred. Associating information about where the event occurred within the network provides a means of investigating an attack; recognizing resource utilization or capacity thresholds; or identifying an improperly configured network element.

Check content

Review the SDN controller configuration to determine if the audit records will note where (i.e. service, interface, node, link, etc.) the event that is being logged occurred. If the SDN controller is not configured to produce audit records containing information to establish where (i.e. service, interface, node, link, etc.) the events occurred, this is a finding.

Fix text

Configure the SDN controller to include where (i.e. service, interface, node, link, etc.) the event occurred 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.
