How do inherent risk and control risk differ from detection risk?

Inherent risk and control risk differ from detection risk in that inherent risk and control risk exist independent of the audit; that is, the levels of inherent risk and control risk are functions of the client and its environment. The auditor has little control over these risks. The auditor can control detection risk through the scope (nature, timing, and extent) of the audit procedures performed. Thus, detection risk has an inverse relationship with inherent risk and control risk.
