1 00:00:00,150 --> 00:00:05,660 All right, folks, so now we are in the next scan, that's a custom board scan. 2 00:00:05,700 --> 00:00:12,340 This is pretty cool, although we have learned about board scanning, but this is a step beyond that 3 00:00:12,660 --> 00:00:16,920 and going a bit more flexible, but more specific as well. 4 00:00:17,610 --> 00:00:20,090 So enough talking. 5 00:00:20,160 --> 00:00:22,310 Let's get started to the lab. 6 00:00:23,640 --> 00:00:24,080 All right. 7 00:00:24,090 --> 00:00:26,970 So we are on the map now. 8 00:00:29,030 --> 00:00:35,310 Now, what happened with this is basically we have already seen just to specify a certain board we can 9 00:00:35,310 --> 00:00:43,500 make use of minus B, whether we do these in scan or we do the DCP scan, we can just make use of, 10 00:00:43,710 --> 00:00:48,310 you know, those minus B and we can specify A. 11 00:00:48,780 --> 00:00:56,310 And of course, our target one, not one forty one, because we just get to know the port is open or 12 00:00:56,310 --> 00:00:56,580 not. 13 00:00:57,000 --> 00:01:02,820 Now what happened is if you let's say you don't specify the board. 14 00:01:02,820 --> 00:01:03,210 No. 15 00:01:05,250 --> 00:01:13,650 What happened when you don't specify the number by default and the maps scanned for 1000 points by default, 16 00:01:14,160 --> 00:01:15,690 that's the default behavior. 17 00:01:15,930 --> 00:01:21,080 If you don't specify any port by default, scan four thousand ports. 18 00:01:21,780 --> 00:01:25,110 OK, and now what happened next? 19 00:01:25,410 --> 00:01:33,320 If you can be very specific, you can make sure you can just, you know, scan for just 500 points. 20 00:01:33,780 --> 00:01:39,810 So when you use minus F, it indicates that you you want to go for fast mode. 21 00:01:40,110 --> 00:01:47,230 Fast mode is basically and method and map just uses top 100 ports. 22 00:01:47,300 --> 00:01:57,020 OK, so this because we already have not more than 20 or 25 ports, so we can see the different business 23 00:01:57,480 --> 00:02:04,170 when you want to limit the number of ports and you just want to be specific about top hundred recommended 24 00:02:04,170 --> 00:02:05,860 broadband map, you can go for that. 25 00:02:06,570 --> 00:02:07,010 All right. 26 00:02:07,260 --> 00:02:09,280 But you can be even more specific. 27 00:02:09,300 --> 00:02:17,750 You can even make use of command ports and you can say to yourself, OK, I don't even want to go for 28 00:02:18,060 --> 00:02:18,180 it. 29 00:02:18,180 --> 00:02:21,710 I just want to be very specific, like top 10 ports. 30 00:02:21,720 --> 00:02:31,230 So it will be looking for top 10 popular ports, which are found to be more vulnerable and more critical 31 00:02:31,230 --> 00:02:33,450 Asper and MAP recommendations. 32 00:02:33,600 --> 00:02:34,930 So you can type then. 33 00:02:35,250 --> 00:02:38,400 So now you see the list of somewhere around 20. 34 00:02:38,820 --> 00:02:40,080 Now you see less than that. 35 00:02:40,510 --> 00:02:41,910 You see there's only 10. 36 00:02:42,190 --> 00:02:46,520 OK, now let's let's do much more good stuff. 37 00:02:46,860 --> 00:02:50,730 Let's say you want to be very specific about the port you want to scan. 38 00:02:51,030 --> 00:02:55,170 OK, so I can specify the port range as well. 39 00:02:55,170 --> 00:02:58,320 So I can specify minus B. 40 00:02:59,660 --> 00:03:09,380 That's a one to maybe one zero to two, and this will scan bought only from the range one two one zero. 41 00:03:09,880 --> 00:03:13,070 OK, now there's one more quick and. 42 00:03:14,030 --> 00:03:21,680 Interesting stuff, you can also do one more thing, you can specify the port range saying one two one 43 00:03:21,680 --> 00:03:24,130 zero three one zero two three. 44 00:03:24,380 --> 00:03:26,850 And also, what about the rest of the port? 45 00:03:26,870 --> 00:03:29,830 There are more than sixty five thousand ports, right? 46 00:03:30,200 --> 00:03:37,820 So you can scan for one zero two four four one zero two four first as a mandatory. 47 00:03:37,850 --> 00:03:42,620 OK, so one two one zero two three will be mandatory scan. 48 00:03:43,020 --> 00:03:46,610 The rest, it will be all based on the recommendation. 49 00:03:46,850 --> 00:03:50,960 So let's say you specify from one zero to three comma. 50 00:03:52,170 --> 00:04:00,770 Gomaa one zero two four beyond one zero two four should be based on an map recommendation. 51 00:04:01,650 --> 00:04:02,380 You got my point. 52 00:04:02,430 --> 00:04:03,720 It's that interesting. 53 00:04:04,080 --> 00:04:04,770 So what do you say? 54 00:04:04,770 --> 00:04:14,730 Is you going to be mandatorily scanning washboards, host for against board one two one zero two, three. 55 00:04:15,090 --> 00:04:20,150 And then in the bracket you say, OK, this is based beyond one zero to four. 56 00:04:20,150 --> 00:04:25,980 It should be based on and my recommendation should be the board registered under the map. 57 00:04:27,390 --> 00:04:30,840 And based on that, this scan should be conducted once you do that. 58 00:04:32,380 --> 00:04:40,660 This can basically happen, so you see this time it went beyond one zero to four, but it only selected 59 00:04:40,660 --> 00:04:45,600 ports which are under and mapped register. 60 00:04:45,610 --> 00:04:47,620 I mean, those are unmap, registered for. 61 00:04:48,840 --> 00:04:55,140 All right, so I hope you got the point, this is pretty, pretty interesting stuff. 62 00:04:55,410 --> 00:05:05,340 This helps in to find a lot of more abilities because, you know, making use of on the board, making 63 00:05:05,340 --> 00:05:14,520 use of 65000 boards can take a whole lot of time, as we know that by default and map can scan thousand 64 00:05:14,520 --> 00:05:14,850 ports. 65 00:05:14,850 --> 00:05:15,140 Right. 66 00:05:15,450 --> 00:05:17,510 But there are 65000 ports. 67 00:05:17,850 --> 00:05:25,140 But if we scan with all the ports going to take on a whole lot of time to scan on data network of maybe 68 00:05:25,140 --> 00:05:30,370 a thousand devices, but skipping any one of the port can be risky as well. 69 00:05:30,780 --> 00:05:32,310 So and help us. 70 00:05:32,310 --> 00:05:38,450 But some you know, some recommended and recommended port or registered board as well. 71 00:05:38,820 --> 00:05:45,930 So that way it becomes very, very hard us to understand any vulnerability based on the ports or unwanted 72 00:05:45,930 --> 00:05:51,180 services on the machine and performing some security on its regular security orders. 73 00:05:51,420 --> 00:05:56,560 So this man dismantled the custom board scanning method, really helped out. 74 00:05:56,850 --> 00:05:57,230 All right. 75 00:05:57,990 --> 00:05:58,650 Thank you so much. 76 00:05:58,680 --> 00:06:00,000 I hope you like this video. 77 00:06:00,000 --> 00:06:00,900 Will catch the next.
