Information security, cybersecurity and privacy protection - Evaluation criteria for IT security - Part 3: Security assurance components (ISO/IEC DIS 15408-3:2024)

This document defines the assurance requirements of the ISO/IEC 15408 series. It includes the individual assurance components from which the evaluation assurance levels and other packages contained in ISO/IEC 15408-5 are composed, and the criteria for evaluation of Protection Profiles (PPs), PP-Configurations, PP-Modules, and Security Targets (STs).

Overview

prEN ISO/IEC 15408-3 (ISO/IEC DIS 15408-3:2024) is Part 3 of the ISO/IEC 15408 series (Common Criteria) and defines the security assurance components used to assess the trustworthiness of IT products, systems and their development processes. The document specifies the assurance requirements, component structure and the criteria for evaluation of Protection Profiles (PPs), PP‑Configurations, PP‑Modules, and Security Targets (STs). It also describes how individual assurance components combine to form Evaluation Assurance Levels (EALs) and other assurance packages (see ISO/IEC 15408‑5).

Keywords: ISO/IEC 15408-3, Common Criteria, security assurance components, evaluation assurance levels, Protection Profile, Security Target, IT security evaluation, cybersecurity standard, privacy protection.

Key Topics

• Assurance paradigm and evaluation approach
  • Concepts behind assurance, vulnerability significance and causes, and assurance through independent evaluation.
  • Use of an evaluation assurance scale to express reviewer confidence.
• Component taxonomy and structure
  • Hierarchy of assurance classes → families → components → elements.
  • Standardized naming, objectives, levelling and dependencies for each component.
• Component content and rules
  • Component objectives, application notes, levelling rules and assurance elements that form measurable evaluation criteria.
• Evaluation criteria for PPs and PP configurations
  • Classes and components specifically for PP evaluation (e.g., APE_* components such as APE_CCL, APE_ECD, APE_INT, APE_OBJ, APE_REQ, APE_SPD).
  • Components for PP‑Module and PP‑Configuration evaluation (ACE_* components including ACE_CCL, ACE_CCO, ACE_ECD, ACE_INT, ACE_MCO).
• Assurance class and family definitions
  • Guidance on how families are grouped, how component levelling works, and how to apply components to different assurance targets.

Applications

• Product and system certification: Laboratories and certification bodies use these components to assess and certify IT products, security functions, and development lifecycle activities.
• Protection Profile development: PP authors apply the component definitions and levelling rules to create PPs that are consistent, testable and suitable for evaluation.
• Procurement and assurance claims: Procurement officers, integrators and regulators can reference assurance components and evaluation criteria to specify required assurance levels in tenders and regulations.
• Security engineering and compliance: Security architects, developers and privacy officers use the standard to align development and documentation with internationally recognized assurance requirements.

Who should use this standard

• Certification bodies and evaluation laboratories
• Security product vendors and PP authors
• Procurement, risk and compliance teams
• Regulators and standards harmonization committees

Related standards

• ISO/IEC 15408 series (Common Criteria) - Parts 1, 2 and 5 (context and security functional components and packages)
• National scheme implementation guides and certification policies that adopt Common Criteria components

This part consolidates the assurance building blocks that underpin Common Criteria evaluations, enabling consistent, repeatable assessment of IT security, cybersecurity and privacy protection.
