What are vulnerability tests in a security program?

In the context of a security and protection system, vulnerability tests—also known as "created-error" checks—are essential procedures used to evaluate the effectiveness of management controls and security systems.1

Because control systems are not self-administering, they require periodic testing and policing to ensure they function as intended. A vulnerability test involves deliberately planting an error or a security breach within a system—such as an erroneous invoice—to determine whether the system successfully detects and reports the irregularity.1

Beyond these specific tests, security programs often utilize other monitoring methods, such as employing undercover investigators or "shoppers" to observe the honesty of personnel and the overall operation of control systems. These measures are vital for maintaining the integrity of personnel security and ensuring that established procedures effectively protect against both internal and external threats.1
