MNT-01: Maintenance Operations

There is no evidence of a capability to develop, disseminate, review & update procedures to facilitate the implementation of maintenance controls across the enterprise.

Maintenance (MNT) efforts are ad hoc and inconsistent. CMM Level 1 control maturity would reasonably expect all, or at least most, the following criteria to exist:

• IT personnel use an informal process to implement secure and timely technology asset-specific maintenance operations, including preventative and reactive maintenance operations.
• Facilities management uses an informal process to facilitate the secure and timely implementation of non-IT maintenance operations, including preventative and reactive maintenance operations.
• Maintenance operations are decentralized both in terms of change management and execution.
• Maintenance controls are primarily administrative in nature (e.g., policies & standards) to manage change control processes associated with maintenance operations.

Maintenance (MNT) 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: o Identify cybersecurity and data protection controls to appropriately address applicable statutory, regulatory and contractual requirements for technology asset maintenance. o Develop and disseminate formal guidance to facilitate a localized/regionalized process to implement secure and timely technology asset-specific maintenance operations, including preventative and reactionary maintenance operations.

• Technology asset maintenance is decentralized (e.g., a localized/regionalized function) and uses non-standardized methods to implement secure, resilient and compliant practices.
• IT/cybersecurity personnel:
• Maintenance controls are primarily administrative in nature (e.g., policies & standards) to manage change control processes associated with maintenance operations.
• Asset custodians develop and maintain formalized procedures to conduct controlled and timely maintenance activities throughout the lifecycle of the system, application or service.
• Maintenance operations may be centralized for certain locations (e.g., datacenters) and decentralized for other locations, both in terms of change management and execution.
• Facilities management uses a localized/regionalized process to facilitate the secure and timely implementation of non-IT maintenance operations, including preventative and reactionary maintenance operations.
• Asset custodians track maintenance activities and component failure rates.

Maintenance (MNT) 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:

• The Chief Information Security Officer (CISO), or similar function with technical competence to address cybersecurity concerns, analyzes the organization's business strategy to determine prioritized and authoritative guidance for technology-related maintenance practices.
• The CISO, or similar function, develops a security-focused Concept of Operations (CONOPS) that documents management, operational and technical measures to apply defense-in-depth techniques across the enterprise for technology-related maintenance.
• A Governance, Risk & Compliance (GRC) function, or similar function, provides governance oversight for the implementation of applicable statutory, regulatory and contractual cybersecurity and data protection controls to protect the confidentiality, integrity, availability and safety of the organization's applications, systems, services and data with regards to technology-related maintenance.
• A steering committee is formally established to provide executive oversight of the cybersecurity and data privacy program, including technology-related maintenance.
• IT/cybersecurity personnel develop and disseminate formal practices to implement enterprise-wide capability to conduct secure and timely technology asset-specific maintenance operations, including preventative and reactionary maintenance operations.
• Technology asset-related maintenance operations are centralized in terms of change management and governance. Local/regional practices fall under the broader enterprise-wide technology asset maintenance program.
• Facilities management uses an enterprise-wide process to facilitate the secure and timely implementation of non-IT maintenance operations, including preventative and reactionary maintenance operations. Local/regional practices fall under the broader enterprise-wide facilities management program.
• A Change Control Board (CCB), or similar function, centrally manages the process of IT and non-IT maintenance operations to reduce the chance of business interruptions from maintenance operations.

Maintenance (MNT) 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 develop, disseminate, review & update procedures to facilitate the implementation of maintenance controls across the enterprise.
