Overview

SIST EN ISO/IEC 15408-3:2026 is an international standard that defines security assurance components for information technology (IT) security evaluation. Developed under the ISO/IEC 15408 Common Criteria series, this document offers structured criteria for assessing and validating the security assurance of IT products and systems. Part 3 focuses on the individual assurance components utilized to build Evaluation Assurance Levels (EALs) and other packages outlined in ISO/IEC 15408-5, and provides the rules for evaluating Protection Profiles (PPs), PP-Configurations, PP-Modules, and Security Targets (STs).

The standard plays a critical role in supporting robust information security, cybersecurity, and privacy protection by delivering a common and globally recognized framework for IT security assessment.

Key Topics

SIST EN ISO/IEC 15408-3:2026 covers several core areas relevant to IT security evaluation:

• Security Assurance Components: Detailed descriptions of the building blocks used to develop comprehensive assurance frameworks, structured into classes, families, and elements.
• Evaluation Criteria: Criteria and methods for evaluating Protection Profiles, Security Targets, and their configurations, ensuring thorough security assessments.
• Assurance Paradigm: An overview of how vulnerabilities are identified and addressed, supporting reliable IT product assurance.
• Component Structure: Standardized naming, objectives, dependencies, and levelling of each assurance component for consistency.
• Evaluation Assurance Levels (EALs): Utilization of these components to build stepwise levels of assurance, making comparisons and certifications uniform and transparent.
• Conformance Claims: Processes for documenting claims about compliance and consistency within Protection Profiles and Security Targets.
• Security Problem Definition and Requirements: Guidelines for defining security objectives and mapping required security functions for IT products and systems.

Applications

SIST EN ISO/IEC 15408-3:2026 finds application across a broad spectrum of IT and cybersecurity domains:

• Product Certification: Enables developers and independent evaluators to structure and report on the security properties of software, hardware, and IT systems when seeking certification.
• Procurement: Organizations, including governments and critical infrastructure sectors, can specify required Evaluation Assurance Levels in procurement documents to ensure they acquire products with vetted security assurances.
• Compliance: Facilitates alignment with international and national regulations by providing a recognized method for demonstrating security robustness.
• Development and Design: Assists manufacturers and developers in integrating security from the outset by providing clear benchmarks for designing, developing, and evaluating IT products.
• Risk Management: Supports organizational risk assessment processes by providing a rigorously defined baseline for security evaluation.

Related Standards

ISO/IEC 15408-3:2026 is part of a comprehensive family of standards related to IT security, cybersecurity, and privacy protection:

• ISO/IEC 15408-1: Overview and general model for IT security evaluation (Common Criteria).
• ISO/IEC 15408-2: Security functional components standard.
• ISO/IEC 15408-4: Framework for IT security evaluation.
• ISO/IEC 15408-5: Specification of composed packages, including EALs, built from assurance components in Part 3.
• ISO/IEC 18045: Evaluation methodology for ISO/IEC 15408 series.
• ISO/IEC 27001: Internationally recognized standard for information security management systems (ISMS).

By following SIST EN ISO/IEC 15408-3:2026, organizations can assure stakeholders of robust cybersecurity practices and demonstrate compliance with globally accepted security evaluation methodologies. This standard is crucial for the secure development, procurement, and certification of IT products and services around the world.
