What does the guide provided by ISO/IEC 27041:2015 focus on?

ISO/IEC 27041:2015 specifically addresses the need for guidance on incident investigation and the methods associated with it. It highlights the importance of having effective controls in place to enhance the credibility of evidence and ensure that incident investigations are conducted systematically and effectively. The guideline supports organizations in establishing a framework for managing incidents, thereby ensuring that investigation processes are robust and lead to actionable insights.

While topics like data encryption, cloud security architecture, and employee privacy training are crucial components of an overall information security strategy, they are not the primary focus of ISO/IEC 27041:2015. This standard centers on the structured approach to conducting incident investigations, which is essential for maintaining the integrity and security of information systems. Therefore, the emphasis on incident investigations as outlined in this standard aligns perfectly with the correct answer choice.
