From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux and Secure Boot certificate expiration (lwn.net)

Linux users who have Secure Boot enabled on their systems knowingly or unknowingly rely on a key from Microsoft that is set to expire in September. After that point, Microsoft will no longer use that key to sign the shim first-stage UEFI bootloader that is used by Linux distributions to boot the kernel with Secure Boot. But the replacement key, which has been available since 2023, may not be installed on many systems; worse yet, it may require the hardware vendor to issue an update for the system firmware, which may or may not happen. It seems that the vast majority of systems will not be lost in the shuffle, but it may require extra work from distributors and users.

Even having no pre-boot PIN with SB on is nice, then you only need your user space login where you could even use fingerprint reader if you like. For servers they can already start serving without anyone having to intervene manually (which is nice after power outage, for example).

So yeah, SB, TPM and FDE are a very nice bundle that heavily secures against the most relevant attack vectors.

Yep that's how my desktops and servers are set up. I only recently started adding the TPM PIN to my laptops for a bit of extra protection from cold boot / evil maid attacks.
