00:08.900 --> 00:13.130
Have friends back in this lesson we can learn how to hide this.

00:13.190 --> 00:15.860
So are in our previous lesson.

00:15.930 --> 00:18.330
How will they learn how to install this.

00:18.640 --> 00:24.060
This is what is generally used to establish a secure connection on the Internet.

00:24.200 --> 00:24.800
OK.

00:25.000 --> 00:29.660
And but this is a server can also be hacked by the hackers.

00:29.880 --> 00:30.210
OK.

00:30.210 --> 00:37.710
They can brute force software because the can't is present on a length machine so they can easily use

00:37.950 --> 00:41.210
that user name for cracking the password.

00:41.420 --> 00:41.880
OK.

00:42.000 --> 00:45.500
So how we can protect against these kinds of attack.

00:45.540 --> 00:45.880
OK.

00:45.900 --> 00:53.100
So we can easily protect against these kinds of attacks by disabling the user account and also changing

00:53.100 --> 00:55.280
the part number OK by default.

00:55.290 --> 00:57.660
So we're users don't know what good too.

00:57.860 --> 00:58.320
OK.

00:58.440 --> 01:01.010
So let's see practically how to do this.

01:01.340 --> 01:01.770
OK.

01:01.790 --> 01:08.170
Most thing that you need to do is with sudo access and fine which is present in it.

01:08.240 --> 01:12.250
Yes this is the thing.

01:12.600 --> 01:13.650
OK.

01:15.180 --> 01:22.450
And here come to the bottom and had four lines of code that I'm going to add.

01:22.890 --> 01:24.510
So the first call.

01:24.730 --> 01:25.200
OK.

01:25.200 --> 01:38.540
I want to keep the port number to file by default gives this 22 year old army rule log in say no.

01:38.670 --> 01:39.470
OK.

01:39.990 --> 01:44.100
Just write this data and restart.

01:44.100 --> 01:51.530
This is just so.

01:51.780 --> 01:55.360
And now let's try to connect with this offer.

01:56.280 --> 01:57.160
OK.

01:57.170 --> 02:03.130
Here you can see what I produced in those Google 16.

02:03.280 --> 02:06.200
OK let's try to connect with port number 22.

02:08.050 --> 02:10.270
It says Magro.

02:11.680 --> 02:19.800
Again tried to connect in you got 16 now.

02:20.390 --> 02:22.280
What number 55.

02:25.220 --> 02:28.590
OK now it's showing us the log in box.

02:28.670 --> 02:35.470
So Prashad possible OK.

02:35.600 --> 02:37.730
We have successfully loggin been here.

02:38.140 --> 02:41.020
OK let's exit exit and try to log in as root

02:44.190 --> 02:48.590
and got you know 16 55

02:52.210 --> 02:54.570
key.

02:55.280 --> 02:59.680
My boss would says Access Denied

03:02.620 --> 03:09.710
came this way you can block this or be this group user account and change the part number.

03:09.710 --> 03:10.030
OK.

03:10.030 --> 03:13.940
This is the way of securing our success or.
