The best indicator of executive management's support for IT risk mitigation efforts is the number of executives attending IT security awareness training. This shows that the executives are committed to enhancing their knowledge and skills on IT security issues, and that they are setting a positive example for the rest of the organization. The number of stakeholders involved in IT risk identification workshops, the percentage of corporate budget allocated to IT risk activities, and the percentage of incidents presented to the board are other possible indicators, but they are not as strong as the number of executives attending IT security awareness training.
