1
00:00:00,390 --> 00:00:01,530
Let's do the first scan.

2
00:00:03,980 --> 00:00:06,350
So now let's write our first in map command.

3
00:00:07,470 --> 00:00:11,400
So with this command, we will scan the IP of the callisthenics computer.

4
00:00:12,430 --> 00:00:17,290
So for this just open callisthenics username route, password tour.

5
00:00:18,360 --> 00:00:19,440
And quick terminal.

6
00:00:21,620 --> 00:00:23,750
Learn IP with if config.

7
00:00:27,040 --> 00:00:29,890
And your target IP address, the Anarky.

8
00:00:31,580 --> 00:00:35,540
All right, so here we've entered our own IP information as the target IP.

9
00:00:36,670 --> 00:00:40,620
So how can we find other threads and other targets?

10
00:00:42,390 --> 00:00:47,400
So this is where we should probably talk a little bit about IP and network content.

11
00:00:48,760 --> 00:00:52,990
We briefly mentioned the concept of a rope before.

12
00:00:54,000 --> 00:00:56,650
But let's go into a little more detail.

13
00:01:00,420 --> 00:01:07,710
These concepts are the basic concepts that you can probably encounter in just about all of your penetration

14
00:01:07,710 --> 00:01:13,910
testing might sound a little boring at first, but I really do want to help you master this subject.

15
00:01:14,160 --> 00:01:14,490
Right.

16
00:01:14,970 --> 00:01:17,820
So we got to talk about what is a network.

17
00:01:18,740 --> 00:01:23,510
Yeah, I know we've already defined network in that network.

18
00:01:24,600 --> 00:01:26,530
But let's dive a little deeper, shall we?

19
00:01:29,490 --> 00:01:35,960
So it's a communication system that devices establish with each other in a certain area.

20
00:01:37,000 --> 00:01:40,660
Information and system resources are shared among different users.

21
00:01:41,940 --> 00:01:45,120
And data can also be transferred from one location to another.

22
00:01:48,300 --> 00:01:53,340
And a network is formed just by connecting at least two devices.

23
00:01:55,500 --> 00:02:00,360
Now on the OSI reference model, it's located on layer three.

24
00:02:03,360 --> 00:02:05,370
So what is the ISI reference model?

25
00:02:06,420 --> 00:02:12,150
So if you haven't ever encountered it before the Ossi or Open Systems Interconnection.

26
00:02:13,100 --> 00:02:21,770
Is a model that was developed in 1984 by ISO, which is the International Organization for Standardization.

27
00:02:24,640 --> 00:02:29,110
And before you purchase a computer system prior to an OSHA standard.

28
00:02:30,140 --> 00:02:37,070
Everything from cable to a network, hard drives to network operating systems were custom made for that

29
00:02:37,070 --> 00:02:37,520
company.

30
00:02:38,980 --> 00:02:42,640
Therefore, different devices could not communicate effectively with each other.

31
00:02:45,030 --> 00:02:51,570
So that's why this model quickly became widely accepted and also became a guide for network standards.

32
00:02:54,000 --> 00:02:59,460
So that way, devices manufactured by different companies with the OS high standard.

33
00:03:02,230 --> 00:03:06,070
Basically be able to communicate using the same protocols.

34
00:03:07,640 --> 00:03:11,900
Now, the U.S. model consists of seven different layers.

35
00:03:13,260 --> 00:03:19,740
And here they are, layer seven application, layer six presentation.

36
00:03:20,840 --> 00:03:22,460
Where you're five session.

37
00:03:23,620 --> 00:03:25,330
Layer four transport.

38
00:03:26,360 --> 00:03:28,370
Layer three network.

39
00:03:29,320 --> 00:03:31,240
Layer two Datalink.

40
00:03:32,030 --> 00:03:34,550
And layer one physical.

41
00:03:36,710 --> 00:03:43,520
So for now, we'll leave these layers here, though, throughout the course, we will discuss Ossi additions

42
00:03:44,600 --> 00:03:47,030
when we get to them in related topics.

43
00:03:48,830 --> 00:03:55,190
Now, getting back to the unmap scan that we perform, it will occur on the network layer, which is

44
00:03:55,220 --> 00:03:57,700
ozone layer three now.

45
00:03:58,610 --> 00:04:05,960
So with a scan and map, we'll try out the first 1000 TCP ports that are most commonly used, which

46
00:04:05,960 --> 00:04:10,040
ports are available and what their status is, whether it's on or off.

47
00:04:10,940 --> 00:04:14,360
And then the service names that will be using those sports.

48
00:04:16,250 --> 00:04:19,070
The 1000 TCP ports used by and MAP.

49
00:04:20,060 --> 00:04:26,360
Will come by default, and if we want to change the list of words used, we just need to modify the

50
00:04:26,360 --> 00:04:30,480
file user share and map and map services.

51
00:04:31,130 --> 00:04:32,930
I don't recommend that, though.
