In this section of the course,
we're going to cover two exam objectives
that are focused on the concepts
around permissions and ownership.
These are covered in two domains,
domain two, security,
and domain four, troubleshooting.
We're going to start out by covering objective 2.5.
This state that given a scenario,
you must apply to appropriate access controls.
Then we're going to move into objective 4.4
that states, given a scenario,
you must be able to analyze and troubleshoot user access
and file permissions.
That's right.
This section is all about permissions and ownership,
and we're going to start
by focusing on file and directory permissions
and the way we work with our files and directory ownership
inside of Linux.
Next, we'll talk about special permissions and attributes
within the Linux operating system
and how those are going to be set and modified.
Finally, we're going to discus what to do
when you face permission issues in your system.
As always, we're going to continue
to interlace our hands-on demonstrations
throughout each of these concepts
in our CentOS system
so you can see all of this in real time.
So let's jump into our lessons on permissions and ownership.
