The Nokia router must terminate 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 documented and validated mission requirements.

| Description | ||||
| 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. 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, deallocating associated Transmission Control Protocol/Internet Protocol (TCP/IP) address/port pairs at the operating system level or deallocating networking assignments at the application level if multiple application sessions are using a single, operating system-level network connection. This does not mean the device terminates all sessions or network access; it only ends the inactive session and releases the resources associated with that session. | ||||

Check Text (C-283775r1203370_chk)
Review the Nokia router configuration to verify all network connections associated with a device management session have an idle timeout value set to five minutes or less, as shown in the example below:
- configure system login-control
- info detail | match idle-timeout
idle-timeout 5
If the Nokia router does not terminate the connection associated with a device management session after five minutes of inactivity, this is a finding.
