Overview

kSIST FprEN ISO/IEC 15408-3:2026 – "Information security, cybersecurity and privacy protection - Evaluation criteria for IT security - Part 3: Security assurance components" – is a fundamental part of the ISO/IEC 15408 series. Published by SIST, this standard defines key security assurance requirements used in evaluating the security of IT products and systems. It describes individual security assurance components that make up evaluation assurance levels (EALs) and other packages specified in ISO/IEC 15408-5. Additionally, it establishes criteria for evaluating Protection Profiles (PPs), PP-Configurations, PP-Modules, and Security Targets (STs).

By leveraging the standardized security assurance components described in this document, organizations and evaluators gain a common framework for demonstrating, analyzing, and comparing IT security claims in a rigorous and repeatable way.

Key Topics

• Assurance Requirements: The document details the baseline set of assurance components and how these are combined to form assurance packages and evaluation levels.
• Component Structure: It explains the class, family, and component organization, providing a systematic way to define and apply assurance elements.
• Evaluation of PPs, PP-Modules, and STs: The standard outlines explicit criteria for the assessment of Protection Profiles, modules, and Security Targets, supporting modular and configurable security objectives.
• Assurance Paradigm: Guidance on understanding vulnerabilities, their causes, and the assurance methods used to provide confidence in IT security functions.
• Component Taxonomy and Dependency: Insight into the relationships between various assurance components and how dependencies are managed across packages and evaluation efforts.

Applications

This standard is crucial across several domains and contexts:

• Product Certification: IT product developers can demonstrate compliance with internationally recognized security requirements, facilitating certification under schemes such as Common Criteria.
• Procurement Specifications: Enterprises and government agencies can reference these assurance components in procurement documents to specify desired trust levels for IT products and solutions.
• System Evaluations: Third-party security assessment organizations use the defined components to structure and perform rigorous, repeatable security evaluations.
• Regulatory Compliance: ISO/IEC 15408-3 supports regulatory objectives by providing standardized criteria, promoting mutual recognition and harmonization internationally.
• Framework for Modular Security: By supporting evaluations of Protection Profiles and Security Targets, the standard is ideal for complex systems using modular or component-based security models.

Related Standards

• ISO/IEC 15408-1: Establishes the overall concepts, principles, and general framework of the ISO/IEC 15408 series.
• ISO/IEC 15408-2: Defines security functional requirements and how to specify them for IT products.
• ISO/IEC 15408-4: Focuses on frameworks for developing Protection Profiles, Security Targets, and compliance processes.
• ISO/IEC 15408-5: Contains detailed pre-defined packages, including evaluation assurance levels (EALs), based on components described in ISO/IEC 15408-3.
• ISO/IEC 18045: Details the methodology for IT security evaluation, directly supporting the practical application of the assurance requirements.

Practical Value

Adopting kSIST FprEN ISO/IEC 15408-3:2026 ensures that stakeholders in information security, cybersecurity, and privacy protection benefit from:

• Standardized assessment criteria, resulting in greater consistency in security evaluations.
• International recognition of security assurance, making it easier to trade and deploy IT products globally.
• Clear structure for specifying and achieving required security levels in both products and operational environments.
• Support for modular, flexible evaluation models that match modern IT system architectures.

By aligning with this standard, organizations ensure their IT security claims are credible, comparable, and accepted worldwide, supporting robust information security and privacy protection initiatives.
