The correct answer isISO 27041, which provides formal guidance for establishing, maintaining, and continuously improving adigital forensic capabilitywithin an organization. According to the CHFI v11 syllabus and Exam Blueprint v4, ISO standards play a critical role in ensuring that forensic processes arerepeatable, reliable, legally defensible, and aligned with global best practices.

ISO 27041 specifically focuses onforensic readiness, which involves preparing an organization in advance to efficiently respond to digital incidents. This includes defining forensic policies, identifying evidence sources, ensuring tool and process validation, assigning roles and responsibilities, and integrating forensic procedures into incident response and business continuity plans. CHFI v11 emphasizes forensic readiness as a proactive approach that reduces investigation time, lowers costs, and improves evidence quality during cybercrime investigations.

By contrast, ISO 27037 (Option C) addresses only theidentification, collection, acquisition, and preservationof digital evidence, not the broader capability-building aspect. ISO 27043 (Option A) focuses onincident investigation principles and processes, while ISO 27001 (Option B) defines aninformation security management system (ISMS)and is not specific to digital forensics operations.

Therefore, for ensuring organizational-level forensic capability aligned with internationally recognized standards,ISO 27041is the most appropriate and CHFI v11–aligned answer
