Prevention of damage to, protection of, and restoration of computers, electronic communications systems, electronic communications services, wire communication, and electronic communication, including information contained therein, to ensure its availability, integrity, authentication, confidentiality, and nonrepudiation.

• A. Cybersecurity
• B. Cyber incident
• C. Critical Technology
• D. CNWDI

Answer: (A)

Cybersecurity focuses on preventing damage to, protecting, and restoring computers, electronic communications systems, and the information they carry, so that availability, integrity, authentication, confidentiality, and nonrepudiation are preserved. It covers the protective measures, risk management, and response activities that keep networks and data safe across hardware, software, and communications. The description provided matches this scope directly by stressing prevention, protection, restoration, and the protection of essential security properties like availability and nonrepudiation. The other terms describe either a single event (a cyber incident), a type of asset (critical technology), or an uncommon acronym (CNWDI) rather than the overarching discipline that safeguards these systems and information.
