The term that describes"the prevention of damage to, protection of, and restoration of computers and electronic communication systems/services, including information contained therein, to ensure its availability, integrity, authentication, confidentiality, and non-repudiation"isCybersecurity.
Step-by-Step Breakdown:✅1. Cybersecurity Defined
Cybersecurityfocuses onprotecting networks, systems, and datafrom cyber threats.
It includes measures to ensure:
Availability(data is accessible when needed).
Integrity(data is accurate and unaltered).
Authentication(verifying users' identities).
Confidentiality(ensuring only authorized access).
Non-repudiation(preventing denial of actions).
The definition in the questionaligns directly with cybersecurity principles, making it the best answer.
✅2. Why the Other Answer Choices Are Incorrect:
(B) Data Security❌
Data securityfocusesspecificallyon protectingstored information(e.g., encryption, access controls), but cybersecurity is broader—it includesnetworks, systems, and communication services.
(C) Network Security❌
Network securityis asubset of cybersecuritythat focuses on protectingnetwork infrastructure(e.g., firewalls, intrusion detection systems).
The definition in the question includesmore than just networks, so cybersecurity is the better choice.
(D) Information Security❌
Information security (InfoSec)is related but broader than cybersecurity.
InfoSeccoversphysical and organizational security(e.g., policies, procedures) in addition todigital protections.
CMMC and NIST SP 800-171 define cybersecurityas the protection ofsystems, networks, and data from cyber threats.
DoD Cybersecurity Definitions(aligned with NIST) confirm that cybersecurity is the term thatbest fits the definition in the question.
