Summary

The system must terminate a session if there is a period of inactivity on the user side of 5 minutes or more.

Description

A system can leave a session indefinitely active if it does not have an automatic termination mechanism based on timeout and the user does not close it manually. Failure to control timeouts may allow an attacker to take advantage of unattended sessions and execute actions on behalf of the authenticated user without their authorization. This risk can notably increase its criticality if this is also the behavior of high-privileged administrator accounts, since it would affect the integrity, confidentiality and availability of the system, its users and the information it contains.
