Arcade machines, whether classic or modern, are often targeted by hackers seeking to manipulate gameplay or extract sensitive data. To protect these machines, operators and manufacturers implement several security measures.

1. Physical Security: Reinforced cabinets, tamper-proof locks, and security seals prevent unauthorized access to internal components. Surveillance cameras in arcades also deter tampering.

2. Firmware and Software Updates: Regularly updating firmware and software patches vulnerabilities. Encrypted code and checksums help detect and prevent unauthorized modifications.

3. Secure Hardware Design: Custom circuit boards with anti-tampering features, such as epoxy-coated chips or self-destruct mechanisms for critical components, make reverse engineering difficult.

4. Network Protection: For connected machines, firewalls, VPNs, and strict access controls prevent remote hacking attempts. Offline modes further reduce risks.

5. Operator Vigilance: Training staff to recognize signs of tampering and conducting routine inspections ensures early detection of breaches.

By combining these strategies, arcade machines can remain resilient against hacking, preserving both revenue and player trust.
