Restrict Access To Security FunctionsDescriptionMechanisms exist to ensure security functions are restricted to authorized individuals and enforce least privilege control requirements for necessary job functions.Possible Solutions & ConsiderationsMicro-Small Business (<10 staff) / BLS Firm Size Classes 1-2∙ Secure Baseline Configurations (SBC)∙ Role Based Access Control (RBAC) ∙ Separation of Duties (SoD) ∙ Privileged Account Management (PAM) Small Business (10-49 staff) / BLS Firm Size Classes 3-4∙ Secure Baseline Configurations (SBC)∙ Role Based Access Control (RBAC) ∙ Separation of Duties (SoD) ∙ Privileged Account Management (PAM) Medium Business (50-249 staff) / BLS Firm Size Classes 5-6∙ Secure Baseline Configurations (SBC)∙ Role Based Access Control (RBAC) ∙ Separation of Duties (SoD) ∙ Privileged Account Management (PAM) Large Business (250-999 staff) / BLS Firm Size Classes 7-8∙ Secure Baseline Configurations (SBC)∙ Role Based Access Control (RBAC) ∙ Separation of Duties (SoD) ∙ Privileged Account Management (PAM) Enterprise (> 1,000 staff) / BLS Firm Size Class 9∙ Secure Baseline Configurations (SBC)∙ Role Based Access Control (RBAC) ∙ Separation of Duties (SoD) ∙ Privileged Account Management (PAM) 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 InformallyEndpoint Security (END) domain capabilities are ad hoc and inconsistent. Capability criteria associated with this control may include:▪ Policies, standards & procedures associated with END domain capabilities provide limited coverage due to the depth and breadth of the existing documentation. ▪ Endpoint security management-related activities are decentralized (e.g., a localized/regionalized function) and uses non-standardized methods to implement secure, resilient and compliant practices. Level 2 Planned TrackedEndpoint Security (END) 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 END domain capabilities are formally documented and centrally-managed by the entity. ▪ Standardized Operating Procedures (SOP) associated with END 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 END domain capabilities to address applicable statutory, regulatory and/or contractual requirements for Technology Assets, Applications, Services and/or Data (TAASD). ▪ Endpoint security-related controls are primarily administrative and preventative in nature (e.g., policies, standards and procedures & guidelines). ▪ Endpoint security management may be a defined function (e.g., team or department) or assigned as an additional duty to existing IT and/or cybersecurity personnel. Level 3 Well DefinedConfiguration Management (CFG) 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 CFG 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 CFG domain capabilities are well-documented and kept current by process owners. ▪ A configuration management team, or similar function, is appropriately staffed and supported to implement and maintain CFG domain capabilities. ▪ Technology is leveraged to enhance the efficiency and accuracy of configuration management operations (e.g., Configuration Management Database (CMBD) Asset Management solution). ▪ 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 CFG 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 ensure security functions are restricted to authorized individuals and enforce least privilege control requirements for necessary job functions. 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.
