All right, folks, so now we are in the next scan, that's a custom board scan.
This is pretty cool, although we have learned about board scanning, but this is a step beyond that
and going a bit more flexible, but more specific as well.
So enough talking.
Let's get started to the lab.
All right.
So we are on the map now.
Now, what happened with this is basically we have already seen just to specify a certain board we can
make use of minus B, whether we do these in scan or we do the DCP scan, we can just make use of,
you know, those minus B and we can specify A.
And of course, our target one, not one forty one, because we just get to know the port is open or
not.
Now what happened is if you let's say you don't specify the board.
No.
What happened when you don't specify the number by default and the maps scanned for 1000 points by default,
that's the default behavior.
If you don't specify any port by default, scan four thousand ports.
OK, and now what happened next?
If you can be very specific, you can make sure you can just, you know, scan for just 500 points.
So when you use minus F, it indicates that you you want to go for fast mode.
Fast mode is basically and method and map just uses top 100 ports.
OK, so this because we already have not more than 20 or 25 ports, so we can see the different business
when you want to limit the number of ports and you just want to be specific about top hundred recommended
broadband map, you can go for that.
All right.
But you can be even more specific.
You can even make use of command ports and you can say to yourself, OK, I don't even want to go for
it.
I just want to be very specific, like top 10 ports.
So it will be looking for top 10 popular ports, which are found to be more vulnerable and more critical
Asper and MAP recommendations.
So you can type then.
So now you see the list of somewhere around 20.
Now you see less than that.
You see there's only 10.
OK, now let's let's do much more good stuff.
Let's say you want to be very specific about the port you want to scan.
OK, so I can specify the port range as well.
So I can specify minus B.
That's a one to maybe one zero to two, and this will scan bought only from the range one two one zero.
OK, now there's one more quick and.
Interesting stuff, you can also do one more thing, you can specify the port range saying one two one
zero three one zero two three.
And also, what about the rest of the port?
There are more than sixty five thousand ports, right?
So you can scan for one zero two four four one zero two four first as a mandatory.
OK, so one two one zero two three will be mandatory scan.
The rest, it will be all based on the recommendation.
So let's say you specify from one zero to three comma.
Gomaa one zero two four beyond one zero two four should be based on an map recommendation.
You got my point.
It's that interesting.
So what do you say?
Is you going to be mandatorily scanning washboards, host for against board one two one zero two, three.
And then in the bracket you say, OK, this is based beyond one zero to four.
It should be based on and my recommendation should be the board registered under the map.
And based on that, this scan should be conducted once you do that.
This can basically happen, so you see this time it went beyond one zero to four, but it only selected
ports which are under and mapped register.
I mean, those are unmap, registered for.
All right, so I hope you got the point, this is pretty, pretty interesting stuff.
This helps in to find a lot of more abilities because, you know, making use of on the board, making
use of 65000 boards can take a whole lot of time, as we know that by default and map can scan thousand
ports.
Right.
But there are 65000 ports.
But if we scan with all the ports going to take on a whole lot of time to scan on data network of maybe
a thousand devices, but skipping any one of the port can be risky as well.
So and help us.
But some you know, some recommended and recommended port or registered board as well.
So that way it becomes very, very hard us to understand any vulnerability based on the ports or unwanted
services on the machine and performing some security on its regular security orders.
So this man dismantled the custom board scanning method, really helped out.
All right.
Thank you so much.
I hope you like this video.
Will catch the next.
