In a high-security facility, biometric devices are used for access control. To guarantee that these devices are running only authentic firmware, the facility should employ:

  • Code Signing
  • Firmware Updates
  • Hardware Redundancy
  • Intrusion Detection Systems
Code signing is essential to guarantee that biometric devices are running only authentic firmware. It verifies the authenticity and integrity of the firmware, preventing unauthorized changes. Firmware updates are important but don't guarantee authenticity. Hardware redundancy and intrusion detection systems focus on system reliability and security but not specifically firmware authenticity.
