Unauthorized peripheral connections to arcade machines can compromise gameplay fairness and security. To prevent such issues, consider these effective methods:

1. Physical Locks and Enclosures: Secure USB and other ports with tamper-proof locks or enclosures to prevent unauthorized access.

2. Firmware Updates: Regularly update the machine’s firmware to patch vulnerabilities that could be exploited by malicious devices.

3. Port Disabling: Disable unused ports in the system settings to eliminate potential entry points for unauthorized peripherals.

4. Network Segmentation: Isolate arcade machines on a separate network to reduce the risk of remote hacking or unauthorized device pairing.

5. Monitoring Software: Install security software to detect and block suspicious peripheral connections in real-time.

By implementing these measures, arcade operators can ensure a secure and fair gaming environment for all players.
