COSO’s Take on the Three Lines of Defense
As risks begin to threaten the achievement of company objectives, senior management must determine the appropriate way to respond. Responsibilities and duties must be clearly identified so individuals are aware of their roles in addressing these risks and controls. COSO developed the three lines of defense model that addresses how specific duties related to risks and controls could be assigned and coordinated within the organization to alleviate the threat. Ultimately, the model is designed to ensure individuals within each line of defense are aware of their full responsibilities and how these responsibilities fit into the organization's overall risk and control structure.
