Assessment BoundariesDescriptionMechanisms exist to establish the scope of assessments by defining the assessment boundary, according to people, processes and technology that directly or indirectly impact the confidentiality, integrity, availability and safety of the Technology Assets, Applications, Services and/or Data (TAASD) under review.Possible Solutions & ConsiderationsMicro-Small Business (<10 staff) / BLS Firm Size Classes 1-2∙ Document security assurance requirements for critical systemsSmall Business (10-49 staff) / BLS Firm Size Classes 3-4∙ Security assurance checklist for critical systemsMedium Business (50-249 staff) / BLS Firm Size Classes 5-6∙ Formal information assurance program∙ Security testing and validation Large Business (250-999 staff) / BLS Firm Size Classes 7-8∙ Enterprise information assurance program∙ Independent security testing Enterprise (> 1,000 staff) / BLS Firm Size Class 9∙ Enterprise IA program∙ Formal evaluation (e.g., Common Criteria, FedRAMP) ∙ Continuous assurance monitoring SCR-CMMLevel 0 Not PerformedPractices 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 InformallyInformation Assurance (IAO) domain capabilities are ad hoc and inconsistent. Capability criteria associated with this control may include:▪ Policies, standards & procedures associated with IAO domain capabilities provide limited coverage due to the depth and breadth of the existing documentation. ▪ Pre-production security testing-related activities are decentralized (e.g., a localized/regionalized function) and uses non-standardized methods to implement secure, resilient and compliant practices. ▪ IT and/or cybersecurity personnel implement and maintain an informal process to conduct limited control testing of High Value Assets (HVAs) to meet specific statutory, regulatory and/or contractual requirements for pre-production cybersecurity and data protection control testing. Level 2 Planned TrackedInformation Assurance (IAO) 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 IAO domain capabilities are formally documented and centrally-managed by the entity. ▪ Standardized Operating Procedures (SOP) associated with IAO 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 IAO domain capabilities to address applicable statutory, regulatory and/or contractual requirements for Technology Assets, Applications, Services and/or Data (TAASD). ▪ Information Assurance (IA)-related controls are primarily administrative and preventative in nature (e.g., policies, standards, procedures & guidelines). ▪ IA management may be a defined function (e.g., team or department) or assigned as an additional duty to existing IT and/or cybersecurity personnel. ▪ Pre-production security testing is decentralized (e.g., a localized/regionalized function) and uses non-standardized methods to implement secure, resilient and compliant practices. ▪ IT and/or cybersecurity personnel implement and maintain a limited Information Assurance Program (IAP) capability to conduct limited control testing to meet specific statutory, regulatory and/or contractual requirements for pre-production cybersecurity and data protection control testing. ▪ IAP operations focus on protecting High Value Assets (HVAs), including environments where sensitive/regulated data is stored, transmitted and processed. Level 3 Well DefinedInformation Assurance (IAO) 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 IAO 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 IAO domain capabilities are well-documented and kept current by process owners. ▪ An information assurance team, or similar function, is appropriately staffed and supported to implement and maintain IAO domain capabilities. ▪ Technology is leveraged to enhance the efficiency and accuracy of information assurance operations (e.g., assessment scheduling software, risk assessment software, etc.). ▪ 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 IAO 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 establish the scope of assessments by defining the assessment boundary, according to people, processes and technology that directly or indirectly impact the confidentiality, integrity, availability and safety of the TAASD under review. Level 4 Quantitatively ControlledUtilize 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 ImprovingUtilize 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. 1.
