Ever wondered how SELinux really works?

I found this link and book on G+ today.  It looks like a great primer for learning SELinux.  What is SELinux?  SELinux is a security layer used by several different Linux Distributions to isolate applications from the lower level parts of Linux.  It does this by blocking access to certain functions until you grant it access.  As long as the applications you grant access to aren't infected with a virus or have a security hole it helps alot.  If an approved application does have a problem it prevents it from going beyond the boundaries it is set for.

 

Yeah the book does a better job of explaining it.  So go check it out.

Check out our new sister site and podcast....

Brian has been doing DevOps for years.  Since returning to the consulting world he discovered that a log of people weren't really doing it.  So in an effort to help people get started on their path to DevOps Mastery he created a new Blog and Podcast.  One of the first posts trys to explain it for you and why you need it.  Check it out here. Thanks for your support.

P.S. Don't worry we aren't stopping our podcast.  We have just reformated it and are working on adding ourselves to a new podcast network, The New Tech Podcast Network. Check it out here.

P.S.S. I will have the shows we have done in our new format up there very very soon.
