Vulnerability discussion

Shared accounts do not provide individual accountability for system access and resource usage.Shared user accounts are not permitted on the system.

Check content

Interview the SA to determine if any shared accounts exist. Any shared account must be documented with the IAO. Documentation should include the reason for the account, who has access to this account, and how the risk of using a shared account (which provides no individual identification and accountability) is mitigated. NOTE: As an example, a shared account may be permitted for a help desk or a site security personnel machine, if the machine is stand-alone and has no access to the network.

Fix text

Remove any shared accounts not meeting the exception requirements listed.

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.
