What is cybersecurity?

• A. The protection of internet-connected systems such as hardware, software and data from cyber threats.
• B. The process of building new hardware rapidly.
• C. The study of weather effects on networks.
• D. The management of user accounts.

Answer: (A)

Cybersecurity is the protection of internet-connected systems such as hardware, software, and data from cyber threats. It encompasses the measures, technologies, and processes used to guard these components against attacks like malware, hacking, ransomware, and data breaches, and to ensure confidentiality, integrity, and availability. This definition directly describes safeguarding the whole stack from digital threats, which is why it’s the best fit. The other choices describe unrelated activities—rapid hardware development, weather effects on networks, or simply managing user accounts—which do not capture the protection-focused scope of cybersecurity.
