The issue of greatest concern when evaluating existing controls during a risk assessment is the presence of successive assessments with the same recurring vulnerabilities. This indicates that the controls are ineffective or inadequate in addressing the identified risks, and that the risk management process is not functioning properly. Recurring vulnerabilities expose the enterprise to potential losses, breaches, or incidents that could harm its objectives, reputation, or compliance. Therefore, it is essential to identify the root causes of the recurring vulnerabilities, implement corrective actions, and monitor the effectiveness ofthe controls on a regular basis. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 4, Section 4.2.2, page 183.
