1 00:00:00,280 --> 00:00:05,650 And Lou everybody when it comes to my advanced ethical hacking networking penetration testing goes 2 00:00:16,180 --> 00:00:16,830 okay. 3 00:00:16,890 --> 00:00:22,310 Now we are allowed to secure our network posting first. 4 00:00:22,560 --> 00:00:23,790 We have put a server here. 5 00:00:23,850 --> 00:00:30,240 So let's try to make some free configurations because we have already made it here. 6 00:00:30,240 --> 00:00:35,330 So we put this static is 1 1 and then the first Internet. 7 00:00:35,360 --> 00:00:39,870 So we put we set an IP address for it as it is then. 8 00:00:40,020 --> 00:00:40,630 All right. 9 00:00:40,680 --> 00:00:41,310 And then we put it on. 10 00:00:41,400 --> 00:00:42,210 So that's all we need. 11 00:00:42,300 --> 00:00:48,560 So now let's just put the connection on our server to switch. 12 00:00:49,660 --> 00:00:50,040 OK. 13 00:00:50,070 --> 00:00:52,650 So now we can go into what we do server. 14 00:00:52,650 --> 00:00:55,950 So we are just going to to secure our network. 15 00:00:56,280 --> 00:00:56,670 So. 16 00:00:56,670 --> 00:00:57,240 All right. 17 00:00:57,270 --> 00:00:59,560 So let's let's go and made it. 18 00:00:59,590 --> 00:01:02,740 It's gonna make it. 19 00:01:03,770 --> 00:01:04,280 All right. 20 00:01:04,280 --> 00:01:09,350 So let's go and make it so we get on CLIA. 21 00:01:09,590 --> 00:01:10,310 So we present. 22 00:01:12,020 --> 00:01:12,390 Okay. 23 00:01:12,530 --> 00:01:15,610 So here we are in the water. 24 00:01:15,620 --> 00:01:16,190 Tell me not. 25 00:01:16,550 --> 00:01:20,900 So we have to type in order to go to the shop. 26 00:01:21,230 --> 00:01:21,570 Okay. 27 00:01:21,590 --> 00:01:24,000 Now we can take the container 28 00:01:27,030 --> 00:01:28,640 and we need to go in there. 29 00:01:29,060 --> 00:01:29,790 Yeah OK. 30 00:01:29,840 --> 00:01:31,060 So now we are here. 31 00:01:31,400 --> 00:01:32,750 What are we going to do. 32 00:01:32,750 --> 00:01:36,050 We need to set a password for the router okay. 33 00:01:36,050 --> 00:01:43,660 We can type enable and a quotation mark can now. 34 00:01:43,670 --> 00:01:47,900 So we are going to use the password field and the secret field as well. 35 00:01:48,200 --> 00:01:56,200 Well so we type in a word password and then the Presenter Well we will stubborn and we can type prove 36 00:01:56,360 --> 00:01:59,720 let's say anything in the book password. 37 00:01:59,720 --> 00:02:01,380 John. 38 00:02:01,490 --> 00:02:02,600 John. 39 00:02:02,870 --> 00:02:04,150 1 1 0. 40 00:02:04,280 --> 00:02:09,130 Let's see first see what kind of things we have to use. 41 00:02:09,360 --> 00:02:10,410 OK. 42 00:02:10,700 --> 00:02:11,030 OK. 43 00:02:11,060 --> 00:02:13,430 So John 1 1. 44 00:02:14,240 --> 00:02:14,710 Okay. 45 00:02:15,230 --> 00:02:19,550 So it was our hope and totally changed it like that. 46 00:02:19,580 --> 00:02:21,090 And now we use this secret. 47 00:02:22,340 --> 00:02:26,900 This is the secret that we are going to use this one because we had two options this one. 48 00:02:26,900 --> 00:02:28,530 So we use password already know we are good. 49 00:02:28,750 --> 00:02:31,250 We would use a secret one. 50 00:02:31,250 --> 00:02:31,650 Okay. 51 00:02:31,680 --> 00:02:32,910 So click here. 52 00:02:33,180 --> 00:02:39,060 Secret make it will keep it secret and then of course enter. 53 00:02:39,280 --> 00:02:41,480 Well so far so good. 54 00:02:41,480 --> 00:02:48,260 Now what we are going to do is we are going to try to put a kind of user name in the water so that when 55 00:02:48,260 --> 00:02:55,250 we turn it due to IP address so it will ask us for a user name that we have set and the password as 56 00:02:55,250 --> 00:02:55,540 well. 57 00:02:55,880 --> 00:03:02,340 So let's make it so we take user name and an additional log we can do. 58 00:03:02,540 --> 00:03:03,410 Okay. 59 00:03:03,410 --> 00:03:06,140 So what will we do to do we are going to take. 60 00:03:06,470 --> 00:03:10,060 There was to say there was any is anything. 61 00:03:10,090 --> 00:03:13,990 Oh blah blah blah blah blah blah. 62 00:03:14,160 --> 00:03:18,920 And we can take this again to see what kind of options we have. 63 00:03:18,920 --> 00:03:20,700 We have two options there. 64 00:03:20,810 --> 00:03:27,080 So we can try to set the user pretty good it's really raw or the secret specify the secret for the user 65 00:03:27,380 --> 00:03:31,690 1 for these videos or we are going to just the password again. 66 00:03:31,810 --> 00:03:35,020 So password in that state now. 67 00:03:35,660 --> 00:03:39,680 John 1 1 0 1 2 3 4. 68 00:03:39,790 --> 00:03:40,010 OK. 69 00:03:40,030 --> 00:03:41,490 That's it. 70 00:03:41,810 --> 00:03:42,170 OK. 71 00:03:42,220 --> 00:03:46,010 Now everything is OK so far so good. 72 00:03:46,760 --> 00:03:54,380 So we can close the terminal and let's try to go to any of these computer or we can choose this one 73 00:03:54,470 --> 00:03:55,430 or this one. 74 00:03:55,580 --> 00:03:56,360 It's not a problem. 75 00:03:56,360 --> 00:04:02,330 So you can choose whatever computer you need and a common form of it. 76 00:04:02,420 --> 00:04:05,300 So it again. 77 00:04:05,660 --> 00:04:11,940 Now we are going to tell net the IP address of the order the IP address of Duty is what. 78 00:04:11,940 --> 00:04:17,110 So let's put it here a little bit and we will hover over a mouse. 79 00:04:17,120 --> 00:04:21,060 It's 2 1 for this serial number. 80 00:04:21,110 --> 00:04:23,950 And for us internet is 1 1. 81 00:04:23,960 --> 00:04:26,380 So let's go and try both of them. 82 00:04:26,580 --> 00:04:27,590 Okay. 83 00:04:27,800 --> 00:04:35,620 So let's turn it into 10 and the water is 1 6 8 and it was 1 1. 84 00:04:35,630 --> 00:04:37,520 Yes 1 1. 85 00:04:37,560 --> 00:04:45,490 So we can try to in two ways or do we move. 86 00:04:45,620 --> 00:04:49,420 I mean do we move or save it for now. 87 00:04:49,550 --> 00:04:52,320 Because it it affects on it. 88 00:04:52,510 --> 00:04:52,990 All right. 89 00:04:53,120 --> 00:04:57,850 So we it was easy just to remove it. 90 00:04:58,260 --> 00:04:58,820 Yes. 91 00:04:58,940 --> 00:05:01,010 The icon visible in you. 92 00:05:01,600 --> 00:05:04,200 And on anything you put it between us. 93 00:05:04,420 --> 00:05:04,830 You see. 94 00:05:05,020 --> 00:05:08,080 So let's waste control or. 95 00:05:08,350 --> 00:05:09,090 Light. 96 00:05:09,130 --> 00:05:14,120 And then now with a C so that we don't have a discourse on almost anymore. 97 00:05:14,280 --> 00:05:17,710 All right so now let's go here again on terminal 98 00:05:21,210 --> 00:05:25,940 cancer knowledge type line machine. 99 00:05:26,360 --> 00:05:32,630 We will use this one good deed be zero 15. 100 00:05:32,850 --> 00:05:33,310 All right. 101 00:05:33,370 --> 00:05:38,510 So let's just as you will to call. 102 00:05:40,040 --> 00:05:41,480 So far so good. 103 00:05:44,580 --> 00:05:48,310 Now we can type game and information. 104 00:05:48,380 --> 00:05:51,080 We will just roll call. 105 00:05:51,910 --> 00:06:02,470 Okay so now when we check if the password is working so we can close it or not and go here I try to 106 00:06:02,490 --> 00:06:04,200 turn at it. 107 00:06:04,630 --> 00:06:07,820 Let's go again. 108 00:06:07,840 --> 00:06:09,070 Let's try it right now. 109 00:06:09,120 --> 00:06:10,740 Okay. 110 00:06:11,060 --> 00:06:15,640 Yeah let's try struck again that it was the IP address of the order. 111 00:06:15,790 --> 00:06:21,330 It's this 1 1 6 8 1 1 1 center. 112 00:06:22,210 --> 00:06:23,000 Okay. 113 00:06:23,020 --> 00:06:25,200 So after that we are haven. 114 00:06:25,210 --> 00:06:26,700 Now we have to put deals in. 115 00:06:26,860 --> 00:06:30,510 So what was always in awe or using it was blah blah. 116 00:06:30,580 --> 00:06:35,100 And Representative and did it pass what was on the Big J. 117 00:06:35,560 --> 00:06:38,080 In a 1 2 3 4. 118 00:06:38,230 --> 00:06:39,660 So wasn't it. 119 00:06:39,670 --> 00:06:40,540 Exactly. 120 00:06:40,570 --> 00:06:42,090 So we are in. 121 00:06:42,400 --> 00:06:43,150 Now we get it. 122 00:06:43,480 --> 00:06:47,060 So we can try to turn at it again from 100 B.C.. 123 00:06:47,160 --> 00:06:53,480 So let's say so we go and try to go from here. 124 00:06:53,560 --> 00:06:56,630 They stop and go on line. 125 00:06:57,640 --> 00:07:07,690 So we take this thing the net the IP address of the 12 1 2 1 6 2 1 6 8 1 1 0. 126 00:07:07,870 --> 00:07:08,550 You can. 127 00:07:08,650 --> 00:07:11,170 This is the first Internet IP address. 128 00:07:11,260 --> 00:07:12,370 If you want it it doesn't matter. 129 00:07:12,370 --> 00:07:14,730 You can choose to do it. 130 00:07:14,740 --> 00:07:17,770 It will be working as well you see. 131 00:07:18,250 --> 00:07:27,520 So the reason that it's working because there is is this IP address and then the one one is this IP 132 00:07:27,520 --> 00:07:27,950 address. 133 00:07:27,970 --> 00:07:32,220 Let me show you just a hover over my mouse here. 134 00:07:32,320 --> 00:07:35,840 And then you see it with the wind. 135 00:07:35,910 --> 00:07:36,360 Okay. 136 00:07:36,370 --> 00:07:37,990 Their business is 1 1. 137 00:07:37,990 --> 00:07:43,250 And so your 0 2 0 IP address is 2 1 slash 30. 138 00:07:43,300 --> 00:07:43,960 All right. 139 00:07:44,020 --> 00:07:46,160 So it's got you again. 140 00:07:46,300 --> 00:07:48,080 And I can type or using them. 141 00:07:48,110 --> 00:07:48,680 OK. 142 00:07:48,730 --> 00:07:51,030 It was already time to time it out. 143 00:07:51,760 --> 00:07:52,630 Let's do it again. 144 00:07:53,680 --> 00:07:55,070 OK. 145 00:07:55,070 --> 00:08:00,090 The password is 1 1 2 3 4 was enter. 146 00:08:00,100 --> 00:08:00,760 Exactly. 147 00:08:00,760 --> 00:08:05,440 So we're getting to be sure that if you want you can put quotation mark right dad and you will have 148 00:08:05,440 --> 00:08:08,680 a lot of options that you can use. 149 00:08:08,680 --> 00:08:09,250 All right. 150 00:08:09,400 --> 00:08:13,900 So let's say that it's a different now. 151 00:08:14,200 --> 00:08:14,930 We exist. 152 00:08:15,010 --> 00:08:18,850 It's trying to thing one IP address. 153 00:08:18,910 --> 00:08:19,860 We are NBC. 154 00:08:21,010 --> 00:08:22,000 We only see one. 155 00:08:22,060 --> 00:08:27,560 Let's try to be an IP address of 0 2. 156 00:08:27,690 --> 00:08:28,150 OK. 157 00:08:28,450 --> 00:08:31,680 Yes strata beneath it being my mistake. 158 00:08:31,870 --> 00:08:39,460 So that can be me say 4 2 6 8 1 8 presenter. 159 00:08:40,280 --> 00:08:44,100 So it will not stop because we would mind Steve. 160 00:08:44,620 --> 00:08:45,090 OK. 161 00:08:45,120 --> 00:08:51,520 And so it's strategy like the idea David Kay. 162 00:08:51,640 --> 00:08:54,290 Now we can go see one. 163 00:08:54,340 --> 00:08:55,150 It was be soon. 164 00:08:55,160 --> 00:08:56,010 Yeah. 165 00:08:56,160 --> 00:08:58,080 So let's put it here. 166 00:08:58,490 --> 00:09:03,870 Now let's go here on ABC call that simply same thing. 167 00:09:04,000 --> 00:09:04,650 Not. 168 00:09:05,110 --> 00:09:19,480 Let's being let's say we would being PCC will you see all you see all of us IP address 1 6 OK 16 being 169 00:09:20,240 --> 00:09:27,310 being minus 3 6 6 1 6. 170 00:09:27,340 --> 00:09:30,000 The presenter. 171 00:09:30,490 --> 00:09:31,140 All right. 172 00:09:31,330 --> 00:09:42,160 So as you see guys the coalition is made from the P.C. one too busy to open the P.C. forward to see 173 00:09:42,550 --> 00:09:44,520 is war it's not a problem. 174 00:09:44,530 --> 00:09:52,240 One thing that you have to be aware after you've set your password or you're sick in your secret in 175 00:09:52,240 --> 00:09:53,190 your username. 176 00:09:53,650 --> 00:09:55,370 If you test it. 177 00:09:55,480 --> 00:09:57,350 It does not work. 178 00:09:57,400 --> 00:10:00,440 It would mean that we could do is in that you have to type. 179 00:10:00,670 --> 00:10:10,370 Let me stop this when commencing coding see we looking to see controversy. 180 00:10:10,400 --> 00:10:11,180 Yeah. 181 00:10:11,590 --> 00:10:18,670 You have to take this command line and breast cancer that you get that option and it will be not here 182 00:10:18,690 --> 00:10:19,290 in the studio. 183 00:10:19,480 --> 00:10:20,960 It should be here. 184 00:10:21,040 --> 00:10:21,840 It should be here. 185 00:10:21,850 --> 00:10:25,490 So you type where it is where it will show you. 186 00:10:25,780 --> 00:10:27,490 We will show it to you at the moment. 187 00:10:27,520 --> 00:10:34,870 Would mean literally to you this one you have to take it first so that it works and take this. 188 00:10:34,870 --> 00:10:37,290 After that you have the real core version. 189 00:10:37,360 --> 00:10:40,530 So this is wrong look wait wait wait after. 190 00:10:41,050 --> 00:10:43,210 If you test it either way it will work. 191 00:10:43,210 --> 00:10:43,450 What. 192 00:10:43,450 --> 00:10:44,800 Before that it will not work. 193 00:10:44,830 --> 00:10:46,200 So be aware of that. 194 00:10:46,210 --> 00:10:46,590 OK. 195 00:10:47,200 --> 00:10:47,860 So that's all. 196 00:10:47,860 --> 00:10:49,780 No for the security part. 197 00:10:49,790 --> 00:10:50,170 OK. 198 00:10:50,290 -->
