CHG-07: Emergency Changes

There is no evidence of a capability to govern change management procedures for "emergency" changes.

C|P-CMM1 is N/A, since a structured process is required to govern change management procedures for "emergency" changes.

Change Management (CHG) 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:

• Change management 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 change management.
• Changes are tracked through a centralized technology solution to submit, review, approve and assign Requests for Change (RFC).
• A Change Advisory Board (CAB), or similar function, exists to govern changes to systems, applications and services to ensure their stability, reliability and predictability.
• A CAB, or similar function, reviews RFCs for cybersecurity and data privacy ramifications.
• A CAB, or similar function, notifies stakeholders to ensure awareness of the impact of proposed changes.
• Logical Access Control (LAC) limits the ability of non-administrators from making unauthorized configuration changes to systems, applications and services.
• Cybersecurity controls are tested after a change is implemented to ensure cybersecurity controls are operating properly.

Change Management (CHG) 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 Exists to govern changes to systems, applications and services to ensure their stability, reliability and predictability. o Reviews RFC for cybersecurity and data privacy ramifications. o Notifies stakeholders to ensure awareness of the impact of proposed changes.

• An IT Asset Management (ITAM) function, or similar function, ensures compliance with requirements for asset management.
• ITAM leverages a Configuration Management Database (CMDB), or similar tool, as the authoritative source of IT assets.
• Logical Access Control (LAC) is governed to limit the ability of non-administrators from making configuration changes to systems, applications and services.
• A formal Change Management (CM) program ensures that no unauthorized changes are made, that all changes are documented, that services are not disrupted and that resources are used efficiently.
• The CM function has formally defined roles and associated responsibilities.
• Changes are tracked through a centralized technology solution to submit, review, approve and assign Requests for Change (RFC).
• A Change Advisory Board (CAB), or similar function:
• IT personnel use dedicated development/test/staging environments to deploy and evaluate changes, wherever technically possible.
• Up on implementing the RFC, the technician implementing a change tests to ensure anti-malware, logging and other cybersecurity and data protection controls are still implemented and operating properly.
• A structured set of controls are tested after a change is implemented to ensure cybersecurity controls are operating properly.
• Results from testing changes are documented.
• A vulnerability assessment is conducted on systems/applications/services to detect any new vulnerabilities that a change may have introduced.

See C|P-CMM3. There are no defined C|P-CMM4 criteria, since it is reasonable to assume a quantitatively-controlled process is not necessary to govern change management procedures for "emergency" 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 govern change management procedures for "emergency" changes.
