Which statement best describes a hacker who operates both offensively and defensively?

• A. A hacker who only uses legal, defensive techniques.
• B. A hacker who conducts illegal activities without any ethical considerations.
• C. A hacker who exclusively works for government agencies.
• D. A hacker who operates both offensively and defensively.

Answer: (D)

Dual-role security professionals who perform both offensive and defensive work sit at the intersection of attacker simulations and defense engineering. They use offensive techniques to reveal vulnerabilities, then implement and validate defensive controls to reduce risk, closing the loop between finding flaws and fixing them. This blended approach is commonly described as a purple team mindset, where offense informs defense and defense improves the effectiveness of future testing. That is why the statement describing a hacker who operates both offensively and defensively is the best fit, because it directly captures the idea of combining attack methods with protective measures. Other descriptions that focus only on defensive work, imply illegal activity, or restrict the role to government employment do not reflect the dual nature of this hacker.
