What is the main purpose of ISO/IEC 27043?

The main purpose of ISO/IEC 27043 is to provide guidelines for incident investigation. This standard specifically focuses on the processes and techniques used in investigating information security incidents, ensuring a systematic and effective approach. It emphasizes the importance of conducting thorough investigations to understand the nature, scope, and impact of incidents, which is crucial for learning from such events and improving overall security posture.

ISO/IEC 27043 also establishes a framework for documenting incidents, which supports transparency and accountability during investigations. This can lead to better responses to future incidents and assists organizations in improving their incident response strategies based on lessons learned. The standard aims to enhance the confidence of stakeholders in an organization's ability to manage and respond to security incidents effectively.

While risk management, data protection, and access control are all critical components of an organization's information security framework, they are not the primary focus of ISO/IEC 27043. The standard is specifically tailored to the investigation aspect, making it a unique and essential tool for organizations aiming to enhance their incident response capabilities.
