COSO ERM for Auditors

What does COSO ERM require of a Auditor?

Committee of Sponsoring Organizations Enterprise Risk Management framework. Under COSO ERM, which defines 20 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 COSO ERM 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.
