The number of business objectives directly supported by information security initiatives is the best indication of information security strategy alignment with the organizational goals and objectives. This metric shows how well the information security strategy is aligned with the business strategy, and how effectively the information security program is delivering value to the organization. The more business objectives that are supported by information security initiatives, the more aligned the information security strategy is with the organizational goals and objectives.
The other options are not the best indicators of information security strategy alignment, as they do not directly measure the impact or contribution of information security initiatives to the business objectives. The percentage of information security incidents resolved within defined SLAs is a measure of the efficiency and effectiveness of the incident management process, but it does not reflect how well the information security strategy is aligned with the business strategy. The percentage of corporate budget allocated to information security initiatives is a measure of the investment and commitment of the organization to information security, but it does not indicate how well the information security initiatives are aligned with the business objectives or how they are prioritized. The number of business executives who have attended information security awareness sessions is a measure of the awareness and involvement of the senior management in information security, but it does not show how well the information security strategy is aligned with the business strategy or how it supports the business objectives.
