Which of the following metrics provides the BEST evidence of alignment of information security governance...

Average return on investment (ROI) associated with security initiatives is the best metric to provide evidence of alignment of information security governance with corporate governance because it demonstrates the value and benefits of security investments to the organization’s strategic goals and objectives. Average number of security incidents across business units is not a good metric because it does not measure the effectiveness or efficiency of security initiatives or their alignment with corporate governance. Mean time to resolution (MTTR) for enterprise-wide security incidents is not a good metric because it does not measure the impact or outcome of security initiatives or their alignment with corporate governance. Number of vulnerabilities identified for high-risk information assets is not a good metric because it does not measure the performance or improvement of security initiatives or their alignment with corporate governance.
