Vulnerability discussion

For completeness of forensic analysis, it is necessary to track who logs on to the DBMS.Concurrent connections by the same user from multiple workstations may be valid use of the system; or such connections may be due to improper circumvention of the requirement to use the CAC for authentication; or they may indicate unauthorized account sharing; or they may be because an account has been compromised.(If the fact of multiple, concurrent logons by a given user can be reliably reconstructed from the log entries for other events (logons/connections; voluntary and involuntary disconnections), then it is not mandatory to create additional log entries specifically for this.)

Check content

Review the DBMS audit settings. If the fact of multiple, concurrent logons by a given user (or other principal) can be reliably reconstructed from the log entries for other events, then this is not a finding. If an audit record is not generated each time a user (or other principal) who is already connected to the DBMS logs on or connects to the DBMS from a different workstation, this is a finding.

Fix text

Configure DBMS audit settings to generate an audit record each time a user (or other principal) who is already connected to the DBMS logs on or connects to the DBMS from a different workstation.

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.
