00:00:00,180 --> 00:00:05,170
Great scene, the last lecture we had a definition of the information security.

2
00:00:05,530 --> 00:00:12,150
Now, as I already mentioned, in the definition of information security, the three main core principles

3
00:00:12,270 --> 00:00:16,980
of information security are the CIA right now.

4
00:00:16,980 --> 00:00:18,970
Let's have a look at the CIA.

5
00:00:19,020 --> 00:00:27,390
Right now, the CIA dryad consists of three important security elements of confidentiality, integrity

6
00:00:27,630 --> 00:00:28,600
and availability.

7
00:00:29,460 --> 00:00:35,070
Now, in this lecture, we are going to just have an overview of the CIA tried.

8
00:00:35,820 --> 00:00:45,180
So the availability stands for property of being accessible and usable on demand by the authorized entity,

9
00:00:45,540 --> 00:00:53,280
which means if there is a data now, if that data is being accessible and usable on demand by any authorized

10
00:00:53,280 --> 00:00:58,920
person, then we can see that the data is being followed, the property of availability.

11
00:00:59,970 --> 00:01:07,170
Next comes confidentiality, which means if the data that the information is not disclosed to unauthorized

12
00:01:07,170 --> 00:01:13,410
individuals, which means the data is only accessible to authorized individuals, then they can see

13
00:01:13,410 --> 00:01:18,530
that the data has been following confidentiality, principle and integrity.

14
00:01:18,540 --> 00:01:23,970
Is that the property of accuracy and the completeness of the data?

15
00:01:24,510 --> 00:01:25,470
Now, don't worry.

16
00:01:25,470 --> 00:01:31,590
If you haven't yet understood these definitions in depth, we are going to see each and every definition

17
00:01:31,590 --> 00:01:33,160
in the upcoming lectures.

18
00:01:33,480 --> 00:01:36,600
I just wanted to give you an overview of the site.

19
00:01:36,600 --> 00:01:36,930
Right.

20
00:01:37,380 --> 00:01:44,400
There are also other factors like authentication, authenticity, accountability, non repudiation and

21
00:01:44,400 --> 00:01:44,850
others.

22
00:01:45,150 --> 00:01:48,780
But all it pinpoints to the CIA tried only.

23
00:01:49,200 --> 00:01:56,400
So whenever you are going to appear for your interviews, make sure that you are completely aware of

24
00:01:56,400 --> 00:02:01,890
the CIA tried because you interview me, ask you about DCI Dry-eyed.

25
00:02:02,310 --> 00:02:05,790
Let us begin with the first element of confidentiality.
