Tamper Resistance And Detection | Inspection Of Information Systems, Components, Or Devices, v1.0

Defines conformance and assessment criteria for verifying that an organization inspects organization-defined information systems, system components, or devices at random, at an organization-defined frequency, or upon organization-defined indications of need for inspection to detect tampering.
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
Tamper Resistance And Detection | Inspection Of Information Systems, Components, Or Devices (TamperResistanceAndDetectionInspectionOfInformationSystemsComponentsOrDevices)
Does the organization inspect [Assignment: organization-defined information systems, system components, or devices] [Selection (one or more): at random; at [Assignment: organization-defined frequency], upon [Assignment: organization-defined indications of need for inspection]] to detect tampering?
Artifacts
A1
Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.
A2
Provide the list/types of organization-defined information systems, system components, and/or devices inspected.
Parameters
Inspection Frequencyrequired
NUMBER : Provide the frequency (in days) at which inspections to detect tampering occur.
Inspection Triggerrequired
ENUM_MULTI : Select the method used to determine when inspections for tempering should occur.
  • At random
  • At an organization-defined frequency
  • Upon organization-defined indications
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 inspects [Assignment: organization-defined information systems, system components, or devices] [Selection (one or more): at random; at [Assignment: organization-defined frequency], upon [Assignment: organization-defined indications of need for inspection]] to detect tampering.
