Nice video

@jay Paul, how do you get your hands on all these awesome videos? specifically the ones from the gentleman Gary Smith?

Thanks for posting! I'm building an ELK and this has been one of the most useful over-views I've seen.

Thanks for this overview sir. I work with Splunk now and I agree, both tools seem very, very similar. I will test ELK out and compare myself . Appreciated-

GOD, a room full of wannabe geeks. They always think they have the answer. Every time someone raises their hand and asks a question, as he's answering their question, 3 other hands go up with "solutions" to the problem. Just let the guy do his talk. I HATE people like that. Unfortunately, lots of IT people share the "I know it all" disease. I've been in IT for 25 years and lots of IT people (who aren't really that good) act like they are better than doctors. It's sickening. I would have made them hold their "questions" until the end. All these assholes want to do is look "smart" and try and see if they can stump the guy giving the talk. I've seen it happen so many times. It's one thing to try and supplement the discussion, but it's just an asshole move to sit there and bring up stupid points.

How do I computer?

Great presentation. I learned a lot. The only thing is that Brian seems to have issues in hearing women out when they speak or have something to contribute. He seems ok with hearing the guys out but every time the woman spoke he sounded annoyed or interrupted her. This is the kind of behavior that keeps us from getting the most out of group of people (women) who are absolutely, positively suited for attention to detail and rooting out what is hidden.

Wow! Thanks for this presentation :-)

LINEUX!

a who dat a blow blow dem nose. have some manners, or go drink little mint tea.. smh..

Nice job. Try using 'iptables-apply' when making changes. It's designed to prevent you from locking yourself out of your system.

Lol murlocs?

*Sorry but this gentleman does not belong teaching this class*.

To that awful person constantly blowing his/her nose. What I do when my nose is stuffed up is to stick some petroleum jelly in my nostrils and this will stop the flow of muucus from coming out. As for IPTables, I run a Linux-based laptop (Fedora). I've used Linux directly since 2005. I have a GUI interface for firewalld. However I read today that if you inadvertently BLOCK the X server, you can end up with a non-bootable system. What us Linux users NEED is a simple to use tool like Windows' ZoneAlarm from the early 2000s.

I couldn't run most of the iptables' command showed in the video :[

Where's all the rest of these linux talks for the NW event?

LinuxFest. Using a Mac. Okay.

Links to those rules and cheatsheet guide would be cool, dude!

Answers to questions: - You can get a list of possible contexts with: seinfo --type - A list of modules: semanage module -l - List your current policy: semanage fcontext -l - Sometimes you need to use audit2allow several times. Recent case: NginX accesing thin's socket at /run/thin/*.sock needed 2 audit2allow; one after another.
