VPM-06.3: Privileged Access

There is no evidence of a capability to implement privileged access authorization for selected vulnerability scanning activities.

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

• Attack Surface Management (ASM) is decentralized.
• IT personnel apply software patches through an informal process.
• Occasional vulnerability scanning is conducted on High Value Assets (HVAs).

Vulnerability & Patch Management (VPM) 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 address applicable statutory, regulatory and contractual requirements for ASM. o Apply software patches and other vulnerability remediation efforts.

• Attack Surface Management (ASM) is decentralized (e.g., a localized/regionalized function) and uses non-standardized methods to implement secure, resilient and compliant practices.
• IT/cybersecurity personnel:
• Administrative processes and technologies focus on protecting High Value Assets (HVAs), including environments where sensitive/regulated data is stored, transmitted and processed.

Vulnerability & Patch Management (VPM) 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 Defines the scope of ASM activities. 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 ASM. o Provides oversight of ASM activities to centrally manage the flaw remediation process as part of the organization's overall Patch& Vulnerability & Patch Management Program (VPMP). o Manages the identification, tracking and remediation of vulnerabilities. o Utilizes a Security Incident Event monitor (SIEM), or similar automated tool, to monitor for unauthorized activities, accounts, connections, devices and software according to organization-specific Indicators of Compromise (IoC), including feeds from applications, hosts, network devices and vulnerability scanners.

• An IT Asset Management (ITAM) function, or similar function, categorizes devices according to the data the asset stores, transmits and/ or processes and applies the appropriate technology controls to protect the asset and data.
• A Governance, Risk & Compliance (GRC) function, or similar function:
• A Security Operations Center (SOC), or similar function:
• Asset custodians install the latest stable version of security-related updates on all systems within the organization-defined time requirements.

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 implement privileged access authorization for selected vulnerability scanning activities.

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 implement privileged access authorization for selected vulnerability scanning activities.
