Battlefield 6 mandates Secure Boot to protect against cheating hacks and ensure fair multiplayer environments. This requirement aligns with EA's anti-cheat policies under tools like PunkBuster or Easy Anti-Cheat, improving PC gaming security and reducing server-side vulnerabilities in modes like Conquest or Warzone.

Key benefits of Secure Boot include:

- Prevention of boot-level malware infections.

- Assurance of firmware integrity and trusted boot chains.

- Support for compliance with standards like Microsoft's Windows Hardware Compatibility.

- Enhanced system reliability and reduced risk of system tampering.

- Compatibility with security mechanisms like Trusted Platform Module (TPM).

Secure Boot is a security feature embedded in UEFI firmware that prevents unauthorized software from loading during the system startup process. It works by verifying the digital signatures of bootloaders, drivers, and other critical components against trusted keys stored in the firmware. This ensures that only authenticated code executes, reducing the risk of malware infections like rootkits.
