Which statement best describes an insider attack?

• A. An attack originating from inside the organization by trusted individuals
• B. An attack that comes from external network
• C. A physical theft of hardware only
• D. An attack that happens randomly

Answer: (A)

An insider attack centers on a threat that originates from within the organization and is carried out by people who already have legitimate access—trusted individuals such as employees, contractors, or partners. These insiders can misuse their privileges to reach sensitive data, bypass controls, or disrupt systems, often without triggering traditional perimeter defenses because their actions appear legitimate. Understanding this helps you see why strong access controls, continuous monitoring, least-privilege principles, and behavior analytics are essential: the risk isn’t just from outsiders, but from those who already have trusted access and may act with malicious intent or due to negligence. The other descriptions miss the core idea: an external attacker operates from outside the organization; hardware theft describes a specific physical act that may or may not involve an insider; a random attack is vague and not tied to trusted insiders.
