LXer: OpenPOWER secure and trusted boot part 2 - Protecting system firmware with OpenPOWER secure boot

Published at LXer:

Protection of system firmware against malicious attack is paramount to server security. If an attacker is able to inject malicious code at the firmware level, no security measure at the operating system level can fully guarantee the trust of the system. IBM OpenPOWER servers support secure boot of system firmware to ensure the system boots only authorized firmware. When the system boots, each firmware component is verified against a cryptographic signature and integrity-checked against a secure hash of the component. If any check fails, secure boot prevents the system from booting until the problem is corrected.
