How does human factors engineering contribute to security?

• A. It focuses only on hardware components.
• B. It reduces human error by designing usable systems and procedures that align with human behavior.
• C. It eliminates the need for security awareness training.
• D. It increases system complexity to deter users.

Answer: (B)

Human factors engineering contributes to security by designing systems, interfaces, and procedures that fit how people actually think and behave. When controls are intuitive and workflows align with everyday tasks, users are less likely to make mistakes that create vulnerabilities, and secure actions become the path of least resistance. This includes clear authentication processes, meaningful feedback, and procedures that support secure behavior without imposing unnecessary friction. By reducing cognitive load and preventing misinterpretations, it lowers the chance of human error that often leads to security breaches. The other approaches miss the user interaction aspect: focusing only on hardware ignores how people use the system; claiming training isn’t needed overlooks the ongoing guidance people rely on; and increasing complexity tends to hamper performance and invites errors.
