๐ ISO 27001 vs ISO 27002 โ Understanding the Difference
Both ISO/IEC 27001 and ISO/IEC 27002 are key standards in information security, but they serve different purposes within an organizationโs security framework.
๐ ISO/IEC 27001 โ The Management System Standard
ISO 27001 defines the requirements for establishing, implementing, maintaining, and continuously improving an Information Security Management System (ISMS).
It focuses on governance, risk assessment, policies, procedures, and continuous improvement.
Key points:
โ๏ธ Risk assessment and risk treatment
โ๏ธ Security governance and leadership
โ๏ธ Security policies and procedures
โ๏ธ Continuous improvement of ISMS
โ๏ธ Certifiable standard
๐ ISO/IEC 27002 โ The Control Guidance Standard
ISO 27002 provides best-practice guidance on how to implement information security controls listed in ISO 27001.
Key points:
โ๏ธ Implementation best practices
โ๏ธ Detailed explanations of security controls
โ๏ธ Reference framework for ISMS controls
โ๏ธ Not a certifiable standard
๐ก Simple Analogy:
๐น ISO 27001 = WHAT to implement (requirements for an ISMS)
๐น ISO 27002 = HOW to implement it (guidance for security controls)
๐ Key Takeaway:
Organizations typically certify against ISO 27001, while ISO 27002 helps them effectively implement and manage the required security controls.
