In security, which term describes attempts to fool the system?

• A. Deception
• B. Spoofing
• C. Phishing
• D. Hijacking

Answer: (A)

Deception describes the broad practice of trying to fool the system or its users by misrepresenting identity, data, or requests. In security, many attacks rely on tricks to bypass controls or elicit credentials, so the overall term that captures these attempts is deception. Specific methods like spoofing (forging a lookalike identity or data), phishing (a deceptive attempt to obtain sensitive information via messages), or hijacking (taking control of a session or device) are techniques within that broader idea. The question is asking for the general concept of attempts to fool the system, making deception the best fit.
