Vulnerability discussion

Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended. In addition, quickly terminating an idle session will also free up resources committed by the managed network element. Terminating network connections associated with communications sessions includes, for example, de-allocating associated TCP/IP address/port pairs at the operating system level, or de-allocating networking assignments at the application level if multiple application sessions are using a single, operating system-level network connection. This does not mean that the device terminates all sessions or network access; it only ends the inactive session and releases the resources associated with that session.

Check content

Verify that RiOS is configured to terminate a device management session at the end of the session, or after 10 minutes of inactivity. Navigate to the device CLI Type: enable Type: show web Verify that "Inactivity Timeout:" is set to "10" minutes -- or -- Navigate to the device Management Console Navigate to Configure >> Security >> Web Settings Verify that "Web Inactivity Timeout (minutes):" is set to "10" If "Inactivity Timeout" or "Web Inactivity Timeout (minutes)" is not set to "10", this is a finding.

Fix text

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.
