What is chea t prevention like anti-cheat, and name two common anti-cheat techniques.

• A. Anti-cheat operates only on the client.
• B. Anti-cheat relies on the user to report cheating.
• C. Anti-cheat detects and prevents cheating; techniques include server-side authority and integrity checks; obfuscation and behavior analysis are others.
• D. Anti-cheat is illegal in most jurisdictions.

Answer: (C)

Anti-cheat systems are designed to detect and prevent cheating in online games by enforcing rules and validating actions even when players try to manipulate the game. A central approach is server-side authority, where the server governs important decisions and checks player actions rather than trusting the client, so tampered data from a cheating program can’t easily override outcomes. Another essential technique is integrity checks, which periodically verify that critical game files and memory haven’t been altered, stopping cheats from injecting unauthorized code or data.

Other common methods include obfuscation, which makes cheat tools harder to analyze and modify, and behavior analysis, which looks for unusual patterns that indicate cheating and flags them for review. This combination captures both prevention and detection, which is why it’s the best description.
