What is the difference between ISO/IEC 20000 and 27001?

ISO/IEC 20000 and 27001 are both internationally recognized standards in the field of information technology management. Although both standards aim to improve the overall efficiency and security of IT services, they have different scopes and focus areas.

Scope and Objective

ISO/IEC 20000, also known as IT service management (ITSM) standard, provides guidelines for implementing an effective IT service management system. It focuses on the delivery and management of IT services, ensuring the alignment of these services with business objectives and customer requirements. The standard covers various aspects such as service design, transition, operation, and continual improvement.

On the other hand, ISO/IEC 27001, also referred to as information security management system (ISMS) standard, deals specifically with information security. It aims to establish a systematic approach to managing and protecting sensitive information within an organization. The scope of ISO/IEC 27001 covers risks related to confidentiality, integrity, and availability of information assets, including both digital and physical information.

Focus Areas

ISO/IEC 20000 primarily focuses on service management processes, ensuring the delivery of high-quality IT services. These processes include service strategy, service design, service transition, service operation, and continual service improvement. The standard emphasizes the importance of customer satisfaction, service level agreements, and service reporting in achieving effective IT service management.

ISO/IEC 27001, however, places its major emphasis on information security risk management. It requires organizations to identify and assess potential risks to their information assets, and implement appropriate controls to mitigate these risks. The standard covers various security domains, including but not limited to access control, asset management, compliance, incident management, business continuity, and system acquisition and development.

Certification Process

To obtain ISO/IEC 20000 certification, organizations need to undergo a formal assessment process conducted by an accredited certification body. This process involves reviewing the organization's documentation, conducting on-site audits, and evaluating the implementation of IT service management processes. Compliance with ISO/IEC 20000 requirements is assessed, and if found satisfactory, the organization receives the certification.

Similarly, for ISO/IEC 27001 certification, organizations must undergo an assessment process to evaluate their information security management system. This process includes a thorough audit of the organization's security controls, policies, procedures, and risk management practices. If the organization meets the requirements outlined in ISO/IEC 27001, certification is granted.

In conclusion, ISO/IEC 20000 and ISO/IEC 27001 are two distinct standards focusing on different aspects of IT management. While ISO/IEC 20000 concentrates on IT service management, ISO/IEC 27001 deals specifically with information security management. Both standards play a crucial role in enhancing an organization's efficiency, reliability, and security when implemented effectively.
