CPL-13: Assurance Levels (AL)

CPL 7 — High Govern

Mechanisms exist to utilize defined Assurance Levels (AL) for assessment activities to standardize the following assurance attributes: (1) Depth that addresses the rigor and level of detail of the assessment; and (2) Coverage that addresses the scope and breadth of the assessment.

Renumbered: Formerly GOV-19.1 in SCF 2025.4.

Control Question: Does the organization utilize defined Assurance Levels (AL) for assessment activities to standardize the following assurance attributes: (1) Depth that addresses the rigor and level of detail of the assessment; and (2) Coverage that addresses the scope and breadth of the assessment?

Capability Maturity Model

Level 0 — Not Performed

Practices are non-existent, based on the inability to demonstrate an implemented and operational capability. A reasonable person would conclude the control is not being performed.

Level 1 — Performed Informally

Cybersecurity & Data Protection Governance (GOV) domain capabilities are ad hoc and inconsistent. Capability criteria associated with this control may include: ▪ Policies, standards & procedures associated with GOV domain capabilities provide limited coverage due to the depth and breadth of the existing documentation. ▪ Governance-related activities are decentralized (e.g., a localized/regionalized function) and uses non-standardized methods to implement secure, resilient and compliant practices. ▪ No formal Governance, Risk & Compliance (GRC) team exists. GRC roles are assigned to existing IT/cybersecurity personnel. ▪ Cybersecurity and data protection governance is informally assigned as an additional duty to existing IT/cybersecurity personnel. ▪ IT /cyber engineering governance is decentralized, with the responsibility for implementing and testing cybersecurity and data protection controls being assigned to the business process owner(s), including the definition and enforcement of roles and responsibilities.

Level 2 — Planned & Tracked

Cybersecurity & Data Protection Governance (GOV) capabilities are requirements-driven, but are not standardized across the entity (e.g., local/regional level consistency). Capability criteria associated with this control reasonably expect the following criteria to exist: ▪ Policies and standards associated with GOV domain capabilities are formally documented and centrally-managed by the entity. ▪ Standardized Operating Procedures (SOP) associated with GOV domain capabilities are documented and maintained by process owners. ▪ IT and/or cybersecurity personnel work with business stakeholders and process owners to appropriately scope and reasonably implement cybersecurity and data protection controls associated with GOV domain capabilities to address applicable statutory, regulatory and/or contractual requirements for Technology Assets, Applications, Services and/or Data (TAASD). ▪ Governance-related controls are primarily administrative and preventative in nature (e.g., policies, standards and procedures & guidelines). ▪ No formal Governance, Risk & Compliance (GRC) team exists. GRC roles are assigned to existing IT and/or cybersecurity personnel.

Level 3 — Well Defined

Compliance (CPL) capabilities are standardized across the entity for applicability to People, Processes, Technologies, Data and/or Facilities (PPTDF) to ensure consistency for Technology Assets, Applications, Services and/or Data (TAASD). Capability criteria associated with this control reasonably expect the following criteria to exist: ▪ Policies and standards associated with CPL domain capabilities are formally documented and centrally-managed by the entity's Governance, Risk & Compliance (GRC) team, or similar function. ▪ Standardized Operating Procedures (SOP) associated with CPL domain capabilities are well-documented and kept current by process owners. ▪ A Governance, Risk & Compliance (GRC) team, or similar function, is appropriately staffed and supported to implement and maintain CPL domain capabilities. ▪ Technology is leveraged to enhance the efficiency and accuracy of governance, risk management and compliance operations (e.g., GRC platform). ▪ The entity's Governance, Risk & Compliance (GRC) team, or similar function, works with business stakeholders and process owners to appropriately scope and reasonably implement cybersecurity and data protection controls associated with CPL domain capabilities to address Minimum Compliance Requirements (MCR) (e.g., applicable statutory, regulatory and/or contractual requirements) and Discretionary Security Requirements (DSR) (e.g., entity-required controls). ▪ An implemented and operational capability exists to utilize defined Assurance Levels (AL) for assessment activities to standardize the following assurance attributes: (1) Depth that addresses the rigor and level of detail of the assessment; and (2) Coverage that addresses the scope and breadth of the assessment.

Level 4 — Quantitatively Controlled

Utilize SCR-CMM Level 3 criteria definitions: ▪ There are no defined Level 4 criteria, since it is reasonable to assume a quantitatively-controlled process is not necessary to operationalize this control. ▪ While it may be possible to develop “metrics-driven” capabilities for this control, the criteria would be organization-specific to define.

Level 5 — Continuously Improving

Utilize SCR-CMM Level 3 or Level 4 (if available) criteria definitions: ▪ There are no defined Level 5 criteria, since it is reasonable to assume a continuously-improving process is not necessary to operationalize this control. ▪ Level 5 capabilities should be considered “world-class” where the control builds on Level 4 capabilities, but are continuously improving through Artificial Intelligence (AI) and/or Machine Learning (ML) technologies. ▪ While it may be possible to develop responsive capabilities for this control through the use of AI and/or ML technologies, the criteria would be organization-specific to define.

Assessment Objectives

  1. CPL-13_A01 Assurance Levels (AL) for assessment activities are defined to standardize assurance attributes.
  2. CPL-13_A02 Assurance Levels (AL) define depth criteria to address the rigor and level of detail of an assessment.
  3. CPL-13_A03 Assurance Levels (AL) define coverage criteria to address the scope and breadth of an assessment.

Evidence Requirements

E-CPL-14 Conformity Attestations & Declarations

Documented evidence of conformity assessment results, attestations and/or declarations of conformity, including the designated certifying official.

Compliance

Technology Recommendations

Micro/Small

  • Define basic assessment depth (documentation review vs. testing)

Small

  • Define assessment depth and coverage criteria in policy

Medium

  • Assurance level definitions in assessment procedures
  • Apply appropriate AL per control criticality

Large

  • Formal assurance level framework
  • Tiered assessment approach by risk level

Enterprise

  • Enterprise assurance level framework
  • Automated control testing for lower-risk controls
  • In-depth testing for critical systems
  • Risk-based assessment scheduling
