ISO 22340:2024

Overview

ISO 22340:2024 - Security and resilience - Protective security - Guidelines for an enterprise protective security architecture and framework - provides high‑level guidance for designing an enterprise protective security architecture and an integrated protective security framework. The standard explains how organizations can align security governance, policies, processes and controls with business objectives using a risk‑based approach. It is applicable to any organization and focuses on coordination across five core protective security domains: security governance, personnel security, information security, cybersecurity, and physical security.

Key Topics

• Enterprise protective security architecture: structure and elements for documenting governance arrangements and the security framework that delivers protective security outcomes.
• Protective security domains: clear coverage of governance, personnel, information, cyber and physical security and how they integrate.
• Risk‑based principles: emphasis on understanding business impact, applying risk management and selecting controls proportionate to risk.
• Security governance: roles and responsibilities including the responsible security executive, security management structures and implementation oversight.
• Personnel security: eligibility, suitability checks, ongoing assessment, separation processes and HR–security cooperation.
• Information security: classification of information, business impact analysis and access control to organizational information.
• Cybersecurity: defining systems, selecting and evaluating cyber controls, system authorization and ongoing monitoring; considerations for rapid digital change.
• Physical security: protecting organizational assets and facilities through policy, procedures and controls.
• Security maturity & continuous improvement: guidance on developing organizational security capability and measuring progress.
• Scope & limitations: provides strategic guidance rather than detailed technical or operational procedures.

Applications

ISO 22340:2024 is intended for managers, security leaders, risk officers and consultants who need to:

• Build or revise an enterprise protective security framework that integrates multiple security disciplines.
• Align security controls with business objectives and risk appetite.
• Define governance structures and clear security roles and responsibilities.
• Guide procurement of security services and design of cross‑domain security programs.
• Improve organizational security maturity and foster a security‑aware culture.

Practical uses include strategic security planning, policy harmonization, vendor requirements for integrated security services, and as a reference when developing organization‑wide protective security roadmaps.
