ISO/IEC 27042:2015 for Auditors
What does ISO/IEC 27042:2015 require of a Auditor?
ISO/IEC 27042:2015 sets out how to analyse and interpret digital evidence so the findings survive scrutiny: continuity records and contemporaneous notes, repeatable and validated methods, a structured path from evidence source to examination to analysis, static and live analysis done without altering the source, facts kept apart from inferences, alternative explanations with their likelihoods, a report planned before the work starts with a minimum content list, and investigators whose competence and proficiency are demonstrated and kept current. 19 guidance leaves read against the complete identical BS EN adoption. Under ISO/IEC 27042:2015, which defines 19 controls, a Auditor's work is deciding which controls you own outright, which you share and which belong to another team, then holding the evidence for the first group.
Which ISO/IEC 27042:2015 controls land on the Auditor
Internal Auditors assess whether compliance controls are operating effectively. They plan and execute audit engagements, evaluate evidence, report findings, and track remediation of identified gaps and nonconformities.
ISO/IEC 27042:2015 defines 19 controls across 7 domains that directly affect the Auditor role. Understanding which controls fall within your ownership, which are shared, and which are owned by other teams is the foundation of effective compliance management.
