Windows WN11-00-000150

DISA STIG WN11-00-000150 (CAT I): Structured Exception Handling Overwrite Protection (SEHOP) must be enabled. = REG_DWORD = 0

DISA STIG recommends

WN11-00-000150 CAT I

Structured Exception Handling Overwrite Protection (SEHOP) must be enabled.

Value: REG_DWORD = 0

NIST SP 800-53: SI-16

Check

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

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.
