Security Considerations

• boot security
  • add BIOS password
  • use motherboard with TPM2.0 and BIOS password not stored in volatile memory
  • use secure boot
  • use full disk encryption with TPM keys
  • disable unneeded device ports in BIOS
• prevent user input
  • blacklist all HID modules
    • usb
    • serial decies /dev/tty* (or more fine-grained) using a udev rule
  • disable unneeded device ports in software
• prevent leakage through network
  • use https
    • use a self-signed certificate as to not worry about expiration
  • use firewall to block all ports except the two needed
• vulnerabilty exploits
  • reduce software stack
  • apply some hardening
  • add update schedule
