The best recommendation to address recent IT risk trends that indicate social engineering attempts are increasing in the organization is to conduct a simulated phishing attack, as it tests the awareness and behavior of the employees in responding to a realistic and targeted email scam, and identifies the areas and individuals that need improvement or training. Updating spam filters, revising the acceptable use policy, and strengthening disciplinary procedures are not the best recommendations, as they may not address the human factor of the risk, or may be too reactive or punitive, respectively.
