OpenBMC (Facebook, Google, Microsoft, Intel, IBM and others) is working on open-source baseboard management software, https://www.linuxfoundation.org/blog/2018/03/openbmc-project... > The organizations behind the new project each have already made substantial contributions to creating open source baseboard management controller (BMC) firmware. Now, working together, they will define the vision for a standard stack th…
Wouldn't help. The BMC hardware has direct serial access to CPUs and other hardware in the machine. Communication is unencrypted. A hardware modification attack wouldn't touch the firmware at all and could still compromise IPMI functionality.
> The system is basically designed to be as insecure as possible by default, and allow for the maximum possible persistent threats with BIOS flashing, IPMI flashing, and other completely un-authenticated avenues exposed.
