ACPI, firmware, and your security
- yuhong 13y agoWell, on x86 there is already SMM and it predates ACPI by years. I believe that ARM SBSA is targeted at only servers, where even HP don't restrict access to firmware updates that solve security bugs.
- noahl 13y agoOn his Google+ page, Shuttleworth says There's a big debate on at the moment about whether to adopt historical, insecure-by-design 'standards' into the next generation of cloud server systems. ACPI, and the whole PC firmware blob mess, are attack vectors that we cannot ever fix. We should not design them into the systems that we and others will depend on being trustworthy. So it looks like this is about servers, and not (necessarily?) phones. (edit: formatting)
