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.

If an attacker has physical access then you're already screwed in most cases.
Pretty much. Even if an attacker can't boot your system, if they have physical access they can just pull your hard drive and mount it on a system they can boot. Only encryption can prevent this. Linux security was originally meant for keeping unprivileged accounts on multiuser systems from messing things up for others on the same machine. It can stretch to some other use cases, but is not a panacea for everything.
And even password based disk encryption can be defeated with 2-3 physical accesses if an organization wants to hard enough. Keyloggers can be very, very sneaky.
At that point you'd have to roll something like Yubikey-based disk encryption to be safe, because this re-establishes control over some physical parts of the system. Until they find the backup Yubikey you had to not lose all data by losing the primary key you're carrying around to maintain control over it.
It's not a battle the defending side can win.
that is unless you're running disk encryption, in which case your data (and in most cases your OS) is safe from unauthorized access, although there is not much to stop them just wiping it or running their own os on it lol
