Every risk should have a risk owner and a control owner . Without ownership, risks won't be managed.
3. Document Risks Clearly
Include information asset description and classification, potential threats, impact and likelihood, existing controls, risk owner, implementation owner, and inherent as well as residual risks .
4. Link to Business Impact
Every risk should be connected to business impact. Without business context, risk priorities are unclear.
