Non-Modifiable Executable Programs | Hardware-Based Protection | Procedures for Managing Write-Protect, v1.0

Defines conformance and assessment criteria for verifying that an organization implements specific procedures for organization-defined authorized individuals to manually disable hardware write-protect for firmware modifications and re-enable the write-protect prior to returning to operational mode.
If an assessment step references organization-defined elements (E.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), corresponding citations/excerpts must be provided to confirm that the organization has established and documented these values and that they apply as referenced in the conformance criteria.

Similarly, if a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]) is specified, evidence must be provided to establish that the option(s) implemented by the organization have been defined and documented.

The assessment step shall not be marked as satisfied without this evidence.

Assessment Step

1
Non-Modifiable Executable Programs | Hardware-Based Protection | Procedures for Managing Write-Protect (Non-ModifiableExecutableProgramsHardware-BasedProtectionProceduresforManagingWrite-Protect)
Does the organization implement specific procedures for [Assignment: organization-defined authorized individuals] to manually disable hardware write-protect for firmware modifications and re-enable the write-protect prior to returning to operational mode?
Artifact
A1
Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.
If conformance criteria reference organization-defined elements (e.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), these values must be defined and documented by the organization.

Similarly, if the criteria specify a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]), the option(s) implemented by the organization must also be defined and documented.

Conformance Criteria (1)

C1
The organization: (a) Employs hardware-based, write-protect for [Assignment: organization-defined information system firmware components]; and (b) Implements specific procedures for [Assignment: organization-defined authorized individuals] to manually disable hardware write-protect for firmware modifications and re-enable the write-protect prior to returning to operational mode.
