Explanation

All four options are correct because network security addresses the four core pillars of information security. Option A covers availability and integrity - ensuring data reaches its destination without loss or corruption from attacks like ransomware or interception. Option B covers data integrity - defending against unauthorized modifications, whether from malicious actors or accidental changes by internal users. Option C covers confidentiality - shielding private data (passwords, financial records, personal communications) from eavesdroppers on the Internet. Option D covers authentication and non-repudiation - preventing impersonation attacks (spoofing) where a malicious user sends messages under a false identity, undermining trust in communications.

Since all four are correct, there are no wrong distractors in this question - it tests whether you recognize that network security is multi-dimensional.

Memory tip: Use the acronym CIA + NR - Confidentiality (C), Integrity (A, B), Availability (A), and Non-Repudiation (D). If you remember these four pillars, you can match any network security rationale back to one of them.
