VACsecured

VACsecured is a security framework used in online multiplayer games to prevent cheating and tampering by securing the game client and its communications.

Key features include code signing and integrity verification of game files, anti-tamper techniques to detect memory modification, server-authoritative game state to minimize client-side trust, secure transport (TLS) for data in transit, and integrity checks for assets at runtime.

Implementation often involves secure update mechanisms, cryptographic checksums, and periodic security audits; deployments are platform-specific.

Criticism and limitations: no system is cheat-proof; false positives; potential performance overhead; privacy concerns; reliance on proper server-side enforcement.

VACsecured remains a conceptual framework in security discussions about online games and should not be confused with real-world proprietary implementations.
