-: In this section of the course,
we're going to talk about access control.
Access control is the different methods that we use
to secure our data and information
by verifying that a user has permission
to read, write, delete, or otherwise, modify it.
Really, what we're talking about
is all of the different permissions
and rights that people have,
and how we control who can touch what
and who can do what with what.
Now, when we start talking about this,
we're going to discuss different methods
or types of access control,
as well as how we have different rights, permissions,
and policies that affects our users
and our information on the network.
Now, as we go through, there's lots of different things
that we're going to use for access control.
When you think of that term,
are you thinking about how people
are touching files and folders?
Are you thinking about how people have access
to log onto a domain or not?
Are you thinking about how people have access
to get into or out of a building?
Well, all of that is access control,
and we're going to discuss a lot of that in this section.
