Who does this work

7 NICE work roles and 5 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.

Log in to the FortiGate GUI with Super-Admin privilege. 1. Open a CLI console, via SSH or available from the GUI. 2. Confirm the output from the following command: # show full-configuration system global | grep -i admin-lockout The output should be: set admin-lockout-duration 900 set admin-lockout-threshold 3 If the admin-lockout-duration is not set to 900 and admin-lockout-threshold is not set to 3, this is a finding.
