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.

I try to follow a multi-factor, multi-domain model.
So if I am wanting to verify that data is on the system I except it to be then TPM keys and measured boot is what I use. To verify it is on the network I expect I use a Tang server. To verify I have possession of a device I use, a hardware token and password.
You could do all the above, or mix match depending on the system. For example for servers I assume they need to boot without user intervention, so password is set as backup to the Tang server. I still use hardware token to buy just for quick revoktion of verification (i.e. I know a server is compromised or could be soon, I can just pull a USB out).
The same setup works for my laptops, which makes my network because of Tang act as trusted domain as well.
So again multi-factor (something you have, know, are, do) and multi-domain (network, user, machine)
