Social engineering exercises are simulations of real-world attacks that exploit human vulnerabilities, such as phishing, baiting, pretexting, or quid pro quo. Conducting social engineering exercises can help assess the risk associated with data loss due to human vulnerabilities by measuring the employees’ susceptibility to such attacks, their awareness of security policies and procedures, and their response to incidents. Reviewing password change history, performing periodic access recertifications, and reviewing the results of security awareness surveys are also useful, but they do not directly test the employees’ behavior and resilience in the face of social engineering attacks.
