SV-52839r1_rule Shared user accounts must not be permitted on the system.

Vulnerability discussion

Shared accounts (accounts where two or more people log in with the same user identification) do not provide adequate identification and authentication. There is no way to provide for nonrepudiation or individual accountability for system access and resource usage.

Check content

Determine whether any shared accounts exist. If no shared accounts exist, this is NA. If shared accounts exist, this is a finding.

Fix text

Remove any shared accounts from the system.

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.
