Security-Enhanced Linux for mere mortals

In the past, Security-Enhanced Linux (SELinux) had a reputation of being hard to configure and maintain. Often, Linux admins would turn it off. But SELinux is an important part of a broad security strategy. It’s now a foundational part of important technologies, such as Linux containers, and supports security and scalability in container offerings, such as Red Hat OpenShift. Through the hard work of the SELinux community, SELinux is now easier to manage than ever.

In this session, we’ll use real-world examples to demonstrate how to use SELinux. You’ll learn the basics of SELinux, including how to:

- Configure SELinux.

- Analyze and correct SELinux errors.

- Set rules and create basic policies for applications on SELinux-protected systems.

my right ear still has no idea what SEL is

The presentation is fantastic.


But what's with Red Hat refusing to adopt the stereo technology?

[RyanEstep]

Hands down. The best explanation that I have ever heard. Thanks.

[dundydunker]

This was one of the most helpful presentations. Knowing now that selinux provides errors with solutions is a life changer for me!

[jacksondaniels]

I really needed this presented just the way you did, this was a really great/clear explanation. The fact that you were able to make this make sense to me of all people, proves you deserve as many gold stars Red Hat can shower down on you.

Preparing for my comptia linux certification... Watched through beginning to end... now I will be re-creating each of these examples in my lab. This is awesome thank you

The most informative and complete SE linux talk I've seen. Very good of your time. Good presenter.

What a great presentation!!. It definitely changed my way of looking at SELinux and it will anyone struggling to understand those key concepts. I will share this video with my colleagues. Thanks for sharing.

[forbinplanet]

Concise, clear and very very useful! I used what I learned here to clear up a problem that I'd been trying to solve for weeks.

[loneosama]

This was really good presentation. My friend had explained me a bit on SE linux earlier so this was a good step up from that

[orbotik]

Saved my butt. Followed along, CLI examples so helpful. No SELinux disables here!

[Trippykiyay]

Best SElinux presentation i have ever seen. THANK YOU!

[carrycat]

All you really need to understand SE Linux - This was very helpful thank you 🙏

Fantastic presentation, learned lot from this, gives me some ideas of how to go about fixing issues with SELinux.

After spending couple of hours testing every example from this video, and fixing SEL issues on authorized_keys file, i feel like I get some new superpower. The feeling is PRICELESS!

Technically speaking the audio is YouTube fault. When you submit it mono audio video (logical when you've recorded with only one mic), YT convert it to stereo but only feed one channel. So yeah it's weird
I suggest that they develop mono audio support to stream just the original mono audio without converting it. And I suggest for the audio engine of every OS to automatically reproduce the sound of feeded channel to non feeded channel automatically (Like if you use 5.1 on a 7.1 or 2.1 on a 5.1 or whatever, no speakers should be left unused, it's annoying)

Just a tips for Windows user out there. Press the windows button and then type "Ease of access audio settings". In the "Turn on mono audio", toggle the button to change it to "On". You're very welcome ;)

Excellent presentation skill! I don't use SELinux in the workplace but I'm confident to say I can handle basic situations by restorecon and semanage.

Brovo, very nice presentation!

Came across this topic today in Redhat Academy. This presentation was really helpful.

This is awesome - watched this and fixed a problem that had been bugging me for days :)
