ISO IEC 27002: Essential Security Controls for AI Systems

ISO/IEC 27002 provides essential guidance for selecting, implementing, and managing information security controls within an Information Security Management System (ISMS). This international standard offers detailed best practice recommendations for protecting organizational information assets, helping businesses establish robust cybersecurity frameworks and achieve compliance with information security requirements.

 

Understanding ISO/IEC 27002: Purpose and Scope

In today's digital landscape, organizations face unprecedented information security challenges from sophisticated cyber threats, data breaches, and evolving regulatory requirements. ISO/IEC 27002 serves as the definitive guide for implementing effective information security management practices, providing organizations with comprehensive frameworks to protect their most valuable digital assets.

The revised ISO 27002:2022 standard represents a significant evolution from its predecessor, addressing modern cybersecurity concepts and emerging threat vectors. This standard bridges the gap between high-level security policies and practical implementation, offering detailed guidance that transforms theoretical security principles into actionable controls.

Developed by ISO/IEC JTC 1/SC 27, the information security subcommittee, this standard builds upon decades of cybersecurity expertise and industry best practices. It serves as the foundation for countless organizations worldwide seeking to establish mature information security management capabilities.

 

Overview of ISO/IEC 27002 and Its Evolution

 

 

Historical Context and Development

ISO/IEC 27002 evolved from ISO/IEC 17799, originally published as BS 7799-1 by the British Standards Institution. This evolution reflects the standard's continuous adaptation to emerging cybersecurity threats and technological advances.

The ISO/IEC 27002:2022 revision represents the most significant update since ISO/IEC 27002:2013, introducing new control categories and streamlining existing recommendations to address current information security risks more effectively.

 

Relationship with ISO/IEC 27001

While ISO/IEC 27001 provides the requirements for establishing an Information Security Management System, ISO/IEC 27002 serves as the implementation guide. This complementary relationship ensures organizations have both the framework (27001) and the detailed guidance (27002) necessary for effective information security management.

The standard directly supports ISO/IEC 27001 certification processes by providing detailed implementation guidance for each control area, making it an essential resource for organizations pursuing formal certification.

 

Key Components and Security Control Categories

Frequently Asked Questions

 

What is the difference between ISO 27002, ISO 27000 and ISO 27001?

ISO 27000 provides the overview and vocabulary for the information security management family of standards. ISO 27001 specifies requirements for establishing an Information Security Management System (ISMS), while ISO/IEC 27002 provides detailed implementation guidance for security controls. Think of 27000 as the introduction, 27001 as the requirements, and 27002 as the implementation guide.

 

Is ISO 27002 mandatory?

ISO/IEC 27002 is not mandatory by law, but it serves as the primary guidance document for implementing ISO 27001 controls. Organizations pursuing ISO 27001 certification typically use 27002 as their implementation guide. Some regulatory frameworks reference these standards, making them effectively mandatory for certain industries or contracts.

 

How does it affect your (re)certification?

The revised ISO 27002:2022 standard introduces new controls and reorganizes existing ones. Organizations with ISO 27001 certification should review their current control implementations against the updated guidance. While existing certifications remain valid, organizations should consider incorporating new controls during their next recertification cycle to maintain optimal security posture.

 

What has changed in ISO 27002:2022?

ISO/IEC 27002:2022 includes significant changes: the number of controls reduced from 114 to 93 through consolidation, new controls address cloud services, data leakage prevention, and threat intelligence. The standard reorganized controls into four themes (Organizational, People, Physical, and Technological) and enhanced guidance for modern cybersecurity challenges including remote work and digital transformation.
