A. B. C. D.A.
The most effective metric to determine the effectiveness of an organization's information security awareness strategy is option A - a decrease in the number of incidents reported by staff. Here's why:
An organization's information security awareness strategy aims to educate staff about potential security threats, how to recognize them, and how to respond to them. The ultimate goal is to reduce the number of security incidents caused by human error or ignorance.
Option A suggests that the number of incidents reported by staff has decreased, which means that staff members are becoming more aware of security threats and taking appropriate measures to prevent them. This is a positive sign that the organization's information security awareness strategy is effective.
Option B - a decrease in the number of email viruses detected - is not a reliable indicator of the effectiveness of the information security awareness strategy. It could mean that the strategy is working, or it could mean that the organization's email filtering system has improved.
Option C - an increase in the number of email viruses detected - is a clear sign that the information security awareness strategy is not working. It suggests that staff members are not able to recognize potential threats and are falling victim to email viruses.
Option D - an increase in the number of incidents reported by staff - could mean that the information security awareness strategy is working, as staff members are becoming more vigilant and reporting incidents that they might have previously ignored. However, it could also mean that the number of security incidents is actually increasing, which is a negative sign.
In summary, the best indicator that an update to an organization's information security awareness strategy is effective is a decrease in the number of incidents reported by staff.
