TPM-05.5: Third-Party Scope Review

There is no evidence of a capability to perform recurring validation of the Responsible, Accountable, Supportive, Consulted & Informed (RASCI) matrix, or similar documentation, to ensure cybersecurity and data protection control assignments accurately reflect current business practices, compliance obligations, technologies and stakeholders.

C|P-CMM1 is N/A, since a structured process is required to perform recurring validation of the Responsible, Accountable, Supportive, Consulted & Informed (RASCI) matrix, or similar documentation, to ensure cybersecurity and data protection control assignments accurately reflect current business practices, compliance obligations, technologies and stakeholders.

Third-Party Management (TPM) 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 Require TSP to follow secure engineering practices as part of a broader Cybersecurity Supply Chain Risk Management (C-SCRM) initiative. o Contain "break clauses" in all TSP contracts to enable penalty-free, early termination of a contract for cause, based on the TSP's cybersecurity and/ or data protection practices deficiency(ies).

• Third-party 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 to address applicable statutory, regulatory and contractual requirements for third-party management.
• A procurement function maintains a list of all active Third-Party Service Providers (TSP), including pertinent contract information that will assist in a risk assessment.
• A Shared Responsibility Matrix (SRM) is documented for every TSP that directly or indirectly affects sensitive/regulated data.
• Procurement contracts:

Third-Party Management (TPM) 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 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 third-party management. o Operates the Cybersecurity Supply Chain Risk Management (C-SCRM) program to identify and mitigate supply chain-related risks and threats. o Evaluates risks associated with weaknesses or deficiencies in supply chain elements identified during first and/ or third-party reviews. o Enables the implementation of third-party management controls. o Ensures the Information Assurance Program (IAP) evaluates applicable cybersecurity and data protection controls as part of “business as usual” pre-production testing. o Maintains a list of all active Third-Party Service Providers (TSP), including pertinent contract information that will assist in a risk assessment. o Requires TSP to follow secure engineering practices as part of a broader Cybersecurity Supply Chain Risk Management (C-SCRM) initiative. o Includes "break clauses" in all TSP contracts to enable penalty-free, early termination of a contract for cause, based on the TSP's cybersecurity and/ or data protection practices deficiency(ies). o Controls changes to services by suppliers, taking into account the criticality of business information, systems and processes that are in scope by the third-party. o Requires a risk assessment prior to the acquisition or outsourcing of technology-related services. o Monitors, regularly reviews and audits supplier service delivery for compliance with established contract agreements. o Uses tailored acquisition strategies, contract tools and procurement methods for the purchase of unique systems, system components or services.

• Procurement contracts and layered defenses provide safeguards to limit harm from potential adversaries who identify and target the organization's supply chain.
• A Governance, Risk & Compliance (GRC) function, or similar function;
• A procurement team, or similar function:
• A Shared Responsibility Matrix (SRM) is documented for every TSP that directly or indirectly affects sensitive/regulated data.

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 perform recurring validation of the Responsible, Accountable, Supportive, Consulted & Informed (RASCI) matrix, or similar documentation, to ensure cybersecurity and data protection control assignments accurately reflect current business practices, compliance obligations, technologies and stakeholders.

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 perform recurring validation of the Responsible, Accountable, Supportive, Consulted & Informed (RASCI) matrix, or similar documentation, to ensure cybersecurity and data protection control assignments accurately reflect current business practices, compliance obligations, technologies and stakeholders.
