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.

Why do we hate SELinux? (lemmy.dbzer0.com)

This is not a troll post. I'm genuinely confused as to why SELinux gets so much of hate. I have to say, I feel that it's a fairly robust system. The times when I had issues with it, I created a custom policy in the relevant directory and things were fixed. Maybe a couple of modules here and there at the most. It took me about 15 minutes max to figure out what permissions were being blocked and copy the commands from. Red Hat's guide.

So yeah, why do we hate SELinux?

Security is much more effective and adopted when it is simple. My understanding is that SELinux is not.

This means not only will fewer people use it and more people turn it off if something doesn't work, it means more people are at risk of misconfiguring their system to allow something they didn't intend to.

This is somewhat mitigated from the fact that, from my experience, Linux Security Modules cant ever make you less secure than without it. But it still can provide a false sense of security if you misconfigure it.

Here is a good article showing what I am referring to, and providing a solid security tool: BSD pledge/unveil on Linux.

SELinux isn't really meant to be a user space "utility," for lack of a better term. It's meant to be an expert focused security framework for those with the expertise to both understand and implement robust security policies. Your average user daily driving Linux or even running a few self hosted services doesn't really need complex security policies, and is definitely better served by some simpler tools.
