Who does this work

7 NICE work roles and 7 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-253284r958928_chk)

Verify SEHOP is turned on. If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SYSTEM\CurrentControlSet\Control\Session Manager\kernel\ Value Name: DisableExceptionChainValidation Value Type: REG_DWORD Value: 0x00000000 (0)

Fix Text (F-56687r828935_fix)

Configure the policy value for Computer Configuration >> Administrative Templates >> MS Security Guide >> "Enable Structured Exception Handling Overwrite Protection (SEHOP)" to "Enabled". This policy setting requires the installation of the SecGuide custom templates included with the STIG package. "SecGuide.admx" and "SecGuide.adml" must be copied to the \Windows\PolicyDefinitions and \Windows\PolicyDefinitions\en-US directories respectively.
