AST-01.1: Asset-Service Dependencies

There is no evidence of a capability to identify and assess the security of Technology Assets, Applications and/or Services (TAAS), Applications and/or Services (TAAS) that support more than one critical business function.

C|P-CMM1 is N/A, since a structured process is required to identify and assess the security of Technology Assets, Applications and/or Services (TAAS), Applications and/or Services (TAAS) that support more than one critical business function.

Asset Management (AST) 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:

• Asset 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 asset management.
• Administrative processes and technologies focus on protecting High Value Assets (HVAs), including environments where sensitive/regulated data is stored, transmitted and processed.
• Asset management is formally assigned as an additional duty to existing IT/cybersecurity personnel.
• Technology assets are categorized according to data classification and business criticality.
• Inventories cover Technology Assets, Applications and/or Services (TAAS) in scope for statutory, regulatory and/ or contractual compliance, which includes both physical and virtual assets.
• Software licensing is tracked as part of IT asset inventories.
• Users are educated on their responsibilities to protect Technology Assets, Applications and/or Services (TAAS) assigned to them or under their supervision.
• IT/cybersecurity personnel maintain network diagrams to document the flow of sensitive/regulated data across the network.
• F or business-critical business services and assets, dependencies are reviewed by cybersecurity personnel for security concerns.

Asset Management (AST) 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:

• An IT Asset Management (ITAM) function, or similar function, governs asset management to help ensure compliance with requirements for asset management.
• An ITAM function, or similar function, maintains an inventory of IT assets, covering both physical and virtual assets, as well as centrally managed asset ownership assignments.
• Technology assets and data are categorized according to data classification and business criticality criteria.
• A Cybersecurity Supply Chain Risk Management (C-SCRM) function oversees supply chain risks including the removal and prevention of certain technology services and/ or equipment designated as supply chain threats by a statutory or regulatory body.
• Data/process owners document where sensitive/regulated data is stored, transmitted and processed, generating Data Flow Diagrams (DFDs) and network diagrams to document the flow of data.
• The CMDB, or similar tool, is leveraged to identify asset-service dependencies that can impact the security of Technology Assets, Applications and/or Services (TAAS), Applications and/or Services (TAAS), as well as relevant stakeholders and data/process owners.
• An IT infrastructure team, or similar function, ensures that statutory, regulatory and contractual cybersecurity and data protection controls are addressed to ensure secure configurations are designed, built and maintained.

Asset Management (AST) 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.

• 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 identify and assess the security of Technology Assets, Applications and/or Services (TAAS), Applications and/or Services (TAAS) that support more than one critical business function.
