The effectiveness of a security awareness training program is best indicated by a reduction in unintentional violations. When employees are well-trained and aware of security practices, they are less likely to inadvertently violate security policies or make mistakes that could lead to breaches. While other factors (such as third-party social engineering tests, employee satisfaction, and completion rates) provide valuable insights, the ultimate goal of security awareness training is to minimize unintentional errors and improve overall security posture12.

* Judgmental Sampling (Option A):Relies on subjective judgment and is less reliable.
* Data Analytics Testing (Option B):Useful for identifying trends but may not assess process maturity comprehensively.
* Variable Sampling (Option C):Appropriate for statistical analysis but less effective in process maturity assessments.
