In this section of the course,
we're going to cover six exam objectives
that are focused on the concepts of cyber security
and the Linux operating system.
So this is going to be a pretty long section of the course,
I'm warning you now.
We're going to be covering six objectives across two domains.
This includes domain one, system management
and domain two, security.
First we'll cover objective 1.2.
This states that given a scenario,
you must manage files and directories.
Then we're going to move into five objectives
focused on security, starting with objective 2.1
which states that you must summarize the purpose
and use of security best practices in a Linux environment.
Then we'll talk about objective 2.2
which states given a scenario,
you must implement identity management.
We'll talk about objective 2.3
that states given a scenario,
you must implement and configure firewalls.
And objective 2.4, it states that given a scenario,
you must configure and execute
remote connectivity for system management.
And finally, objective 2.5, that states given a scenario,
you must apply the appropriate access controls.
This section of the course
is all about discovering the best security practices
that we need to implement
in order to keep our Linux system secure.
Like always, we're going to continue to alternate
between our theory lessons and our hands on demonstrations
throughout each of these concepts
as we go through this section.
All of this is going to be done in real time
using our CentOS system once again.
So let's get started talking all about security
in the Linux operating system in this section of the course.
