-: Network security. 2 2
In this section of the course 3 3
we're going to talk about network security. 4 4
So up to this point, we've really only focused 5 5
on making our networks functional and working 6 6
in order to support our business needs. 7 7
But we really haven't focused a lot on security just yet. 8 8
And now we really need to understand the basics of security, 9 9
the threat against our networks and how to manage the risk 10 10
so that we can effectively use our networks 11 11
to meet the operational needs of our business and its users. 12 12
So in this section of the course, 13 13
we're going to focus on the fundamentals of security, 14 14
including the CIA triad, threats, 15 15
vulnerabilities and exploits, risk management, 16 16
the principles of security, defense in depth 17 17
and our different methods of authentication. 18 18
We're going to be talking all about 19 19
domain 4 network security in this section of the course 20 20
and covering three different objectives, 21 21
namely 4.1, 4.3 and 4.5. 22 22
Objective 4.1 states that you must explain 23 23
common security concepts. 24 24
4.3 states that given a scenario, 25 25
you must apply network hardening techniques, 26 26
and 4.5 states that you must explain the importance 27 27
of physical security. 28 28
So let's get started learning all about network security 29 29
and how to start protecting it networks.
