PES-03: Physical Access Control

There is no evidence of a capability to enforce physical access authorizations for all physical access points (including designated entry/exit points) to facilities (excluding those areas within the facility officially designated as publicly accessible).

C|P-CMM1 is N/A, since a structured process is required to enforce physical access authorizations for all physical access points (including designated entry/exit points) to facilities (excluding those areas within the facility officially designated as publicly accessible).

Physical & Environmental Security (PES) efforts are requirements-driven and governed at a local/regional level, but are not consistent across the organization. CMM Level 2 control maturity would reasonably expect all, or at least most, the following criteria to exist:

• Physical access control is decentralized (e.g., a localized/regionalized function) and uses non-standardized methods to implement secure, resilient and compliant practices.
• IT/cybersecurity personnel identify cybersecurity and data protection controls that are appropriate to address applicable statutory, regulatory and contractual requirements for physical access control.
• Human Resources, or a similar function, maintains a current list of personnel with authorized access to organizational facilities and facilitates the implementation of physical access management controls.
• Physical security controls are primarily administrative in nature (e.g., policies & standards).
• Physical controls, administrative processes and technologies are primarily designed and implemented for offices, rooms and facilities that focus on protecting High Value Assets (HVAs), including environments where sensitive/regulated data is stored, transmitted and processed.
• A facilities maintenance team, or similar function, manages the operation of automated physical and environmental protection controls.
• Physical controls and technologies are configured to enforce physical access authorizations for all physical access points (including designated entry/exit points) to facilities (excluding those areas within the facility officially designated as publicly accessible).

Physical & Environmental Security (PES) efforts are standardized across the organization and centrally managed, where technically feasible, to ensure consistency. CMM Level 3 control maturity would reasonably expect all, or at least most, the following criteria to exist: o Performs the centralized-management of physical security controls across the enterprise. o Maintains a current list of personnel with authorized access to organizational facilities and implements physical access management controls.

• A physical security team, or similar function:
• A facilities maintenance team, or similar function, manages the operation of environmental protection controls.
• Administrative processes exist to authorize physical access to facilities based on the position or role of the individual.
• Administrative processes and physical controls restrict unescorted access to facilities to personnel with required security clearances, formal access authorizations and validated the need for access.
• Physical controls and technologies are configured to enforce physical access authorizations for all physical access points (including designated entry/exit points) to facilities (excluding those areas within the facility officially designated as publicly accessible).

Physical & Environmental Security (PES) efforts are metrics driven and provide sufficient management insight (based on a quantitative understanding of process capabilities) to predict optimal performance, ensure continued operations and identify areas for improvement. In addition to CMM Level 3 criteria, CMM Level 4 control maturity would reasonably expect all, or at least most, the following criteria to exist:

• Metrics reporting includes quantitative analysis of Key Performance Indicators (KPIs).
• Metrics reporting includes quantitative analysis of Key Risk Indicators (KRIs).
• Scope of metrics, KPIs and KRIs covers organization-wide cybersecurity and data protection controls, including functions performed by third-parties.
• Organizational leadership maintains a formal process to objectively review and respond to metrics, KPIs and KRIs (e.g., monthly or quarterly review).
• Based on metrics analysis, process improvement recommendations are submitted for review and are handled in accordance with change control processes.
• Both business and technical stakeholders are involved in reviewing and approving proposed changes.

See C|P-CMM4. There are no defined C|P-CMM5 criteria, since it is reasonable to assume a continuously-improving process is not necessary to enforce physical access authorizations for all physical access points (including designated entry/exit points) to facilities (excluding those areas within the facility officially designated as publicly accessible).
