AST-31: Asset Categorization

AST 9 — Critical Identify

Mechanisms exist to categorize Technology Assets, Applications and/or Services (TAAS).

Control Question: Does the organization categorize Technology Assets, Applications and/or Services (TAAS)?

Capability Maturity Model

Level 0 — Not Performed

There is no evidence of a capability to categorize Technology Assets, Applications and/or Services (TAAS).

Level 1 — Performed Informally

C|P-CMM1 is N/A, since a structured process is required to categorize Technology Assets, Applications and/or Services (TAAS).

Level 2 — Planned & Tracked

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.
  • Data/process owners categorize data in accordance with organizational policies and standards.
Level 3 — Well Defined

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.
  • Data/process owners categorize data in accordance with organizational policies and standards.
  • A data classification process exists to identify categories of data and specific protection requirements.
  • Administrative processes and technologies identify by data classification type to ensure adequate cybersecurity and data protection controls are in place to protect organizational information and individual data privacy.
Level 4 — Quantitatively Controlled

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 categorize Technology Assets, Applications and/or Services (TAAS).

Level 5 — Continuously Improving

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 categorize Technology Assets, Applications and/or Services (TAAS).
