JUEX-NM-000360 - The Juniper EX switch must be configured to end all network connections associated with a device management session at the end of the session, or the session must be terminated after five minutes of inactivity except to fulfill mission requirements.

Information

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.

Solution

Configure the network device to terminate the connection associated with a device management session at the end of the session or after five minutes of inactivity.

There is no configuration required to support explicit logout ('quit' at the end of the session).
1. Enter configuration mode.
2. Configure inactivity timeout for root.
3. Configure inactivity timeout for all login classes.
4. Commit the configuration.

user@host> configure
user@host# set system login idle-timeout 5
user@host# set system login class <class name> idle-timeout 5
user@host# commit
