Hello. My name is Dustin, and welcome to pen test basics. Scanning networks.
00:05
So question one. I'd like to gather more information about what devices air on my network. What is the best way to do? So,
00:14
is it a sniffing?
00:16
Be snooping,
00:18
See, scanning
00:20
or the d scooping?
00:23
And that's kind of the whole point of this module.
00:28
And that's right. Of course it's scanning. In order to gather more information about what's on the network, you should start with scanning, sniffing, maybe another alternative, and we'll talk about that more in the next lesson.
00:42
So I've done a scan on my network and I found a computer 19 to 1 68 Got one about 15. And I'd like to see if the SS H port is open on that PC. Which end map Command? Should I use
01:00
give you second to think about that. There
01:03
we have a couple port options and couple seven and options. Maybe a specific I P.
01:12
That's right. So, in order to scan for just S S H airport 22 on that single device I'd use and map of dash P for Port 22 because we're looking for s h
01:23
And then the I p address
01:29
and last question, I found one computer on my network 1 91 681 15 that has Sshh open. I'd like to see if S H is open on any other computers
01:42
in the network. And this. No, it's just a standard classy network. Which end map command, Should I use?
01:49
Is it a
01:51
and map Dash p 22 19216810 slash 24
01:57
b and map Cache ping 23 1921681 About 15
02:05
See and map Dash P 23 192.168 dot 10 Such 24 Or is it D and map Dash p 22 1921681.15 And we kind of alluded to this in the last one.
02:23
That's correct. In order to scan for that whole network, we would do an app. Dash p. 22
02:32
19216810 slash 24

Pentest Fundamentals: Scanning Networks

In Pentest Fundamentals: Scanning Networks, we explain what scanning is and why its important for a security assessment or maintence. He also discusses NMAP and covers the various types of NMAP techniques to scan a target effectively. Hping, a cmd packet-crafting tool generally used as a network security tool, and PackETH, an alternative of hping.
