The FortiGate device must limit the number of logon and user sessions.

Description
Device management includes the ability to control the number of administrators and management sessions that manage a device. Limiting the number of allowed administrators and sessions per administrator based on account type, role, or access type is helpful in limiting risks related to DoS attacks. This requirement addresses concurrent sessions for administrative accounts and does not address concurrent sessions by a single administrator via multiple administrative accounts. The maximum number of concurrent sessions should be defined based upon mission needs and the operational environment for each system. At a minimum, limits must be set for SSH, HTTPS, account of last resort, and root account sessions.

Who does this work

8 NICE work roles and 6 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-234219r960735_chk)

Log in to the FortiGate GUI with Super-Admin privilege and open a CLI console available from the GUI. or Connect via SSH. Run the following command: show full-configuration sys global | grep -i admin Check the output of the following lines: set admin-concurrent disable set admin-login-max <number as defined by the organization> If set admin-concurrent is not set to disable, this is a finding. If set admin-login-max is not set to a number defined by the organization, this is a finding. The default setting is 100.

Fix Text (F-37369r917461_fix)

Log in to the FortiGate GUI with Super-Admin privilege and open a CLI console available from the GUI. or Connect via SSH. Execute the following commands: config system global set admin-concurrent disable set admin-login-max <number defined by the organization> end With the implementation of this requirement, the organization can limit each administrator to one active session and limit the total number of concurrent administrator sessions to a value deemed appropriate.
