What term describes good hackers who work to protect and strengthen systems?

• A. Black Hat
• B. Grey Hat
• C. White Hat
• D. Blue Hat

Answer: (C)

When people talk about hackers who work to protect and strengthen systems, the term is white hat. These security professionals perform ethical hacking with authorization to identify security gaps and help fix them, strengthening defenses and reducing risk. They might conduct penetration testing, vulnerability assessments, secure software reviews, and incident-response planning to improve an organization’s security posture. Black hat hackers exploit systems for harm, grey hat hackers operate without clear authorization or with mixed motives, and blue hat is a less common label used for security researchers in some environments. So, the best term for those who defend and improve security is white hat.
