@IRJ said in Doublecheck the Security of Your Linux:

Just a couple notes from the article:

You cannot set a bootloader password for AWS or other cloud services

Apt Armor is specific to Ubuntu / Debian. SELinux is used on RHEL / CentOS / Fedora

AppArmor is default on SUSE as well. And you can run SELinux on Debian / Ubuntu if you want.

BTW, AppArmor just replaced SELinux as default on Debian 10. So that was only a couple of months ago.

WSL2 tells us a lot.

First, Microsoft is really making it more known that WSL has no Linux and is just Ubuntu (or whatever) on the Windows kernel.

Second, Microsoft is making it clearer that there was no virtualization going on in WSL.

Third, now there is Hyper-V and a Linux kernel involved. So now it is just virtualizating a Linux instance on top of Windows.

Fourth, now it is much faster. That means that Linux on Hyper-V is faster than Windows on bare metal!
