Data Classification Taxonomy Integration with NIST SP 800-60 Information Types and ISO 27001:2022 Asset Management: Complete Information Asset Protection Framework

What is the NIST SP 800-60 information categorization methodology?

NIST SP 800-60 provides a structured approach for categorizing federal information and information systems according to security objectives of confidentiality, integrity, and availability. The methodology establishes information types based on government functions and business processes, with security categorization levels of low, moderate, or high impact for each security objective.

The framework identifies over 100 information types organized into mission-based and business areas, providing specific guidance for determining security categorization based on potential adverse impact from unauthorized disclosure, modification, or unavailability. Each information type includes base-level impact ratings that organizations can adjust based on specific circumstances and risk assessments.

NIST SP 800-53 Rev 5 security control baselines directly correspond to SP 800-60 categorization levels, ensuring that information categorization drives appropriate control selection and implementation priorities.

How does ISO 27001:2022 approach information asset management and classification?

ISO 27001:2022 Annex A.5 (Information Security in Supplier Relationships) and A.8 (Asset Management) establish comprehensive requirements for identifying, documenting, and protecting information assets throughout their lifecycle. The standard requires organizations to maintain an inventory of assets and assign ownership, classification levels, and handling requirements.

Core ISO 27001:2022 Asset Management Requirements:

• A.8.1 Responsibility for Assets: Assign asset ownership and establish accountability for protection
• A.8.2 Information Classification: Implement classification scheme appropriate to business needs and legal requirements
• A.8.3 Media Handling: Establish procedures for secure handling, storage, transportation, and disposal of classified media

The standard emphasizes risk-based classification where information classification levels should reflect the potential business impact from compromise, aligning with the organization's risk appetite and legal obligations. Classification schemes must consider confidentiality, integrity, availability, and any additional security properties relevant to the business context.
