Vulnerability discussion

Automatic session termination addresses the termination of administrator-initiated logical sessions in contrast to the termination of network connections that are associated with communications sessions (i.e., network disconnect). A logical session (for local, network, and remote access) is initiated whenever an administrator (or process acting on behalf of a user) accesses a network device. Such administrator sessions can be terminated (and thus terminate network administrator access) without terminating network sessions. Session termination terminates all processes associated with an administrator's logical session except those processes that are specifically created by the administrator (i.e., session owner) to continue after the session is terminated. Conditions or trigger events requiring automatic session termination can include, for example, organization-defined periods of user inactivity, targeted responses to certain types of incidents, and time-of-day restrictions on information system use. These conditions will vary across environments and network device types.

Check content

Verify that RiOS is configured to terminate a network administrator's session after a trigger event such as inactivity timeout. Navigate to the device CLI Type: enable Type: show web Verify that "Inactivity Timeout:" is set to the organizations defined condition If no triggers are required by the organization, this is a finding.

Fix text

Configure RiOS to automatically terminate a network administrator's session after a trigger event such as an inactivity timeout. Navigate to the device CLI Type: enable Type: conf t Type: web auto-logout Type: write memory Type: exit Type: show web Verify that "Inactivity Timeout:" represents the value entered above. Type: exit

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.
