I see a Scott of Fundamentals and this mantra will be looking at back net part one.
00:06
And the learning objectives will be looking at back net itself the protocol structure, how it works into interacts with TCP I p networks and using census that i o por back net open source intelligence gathering
00:22
Now, back then, it was created by the American Society of Heating, Refrigerating air conditioning Engineers incorporated The short term port is Astra and it uses, uh, excuse me, is used with building automation and control systems.
00:40
It operates over the UDP packet and the source port in the destination port are the same of 47808
00:52
back office. Also you, you that utilizes XML and html five. And you could take a look at how back networks by going to this. PdF, which explains what back net is on a technical point of view.
01:08
Now the communications methods that back Net uses is back at I p. But that happens to be the most commonly used method for back met. Another method is Ethernet 802.3. There's also point to point M S, T P and something called dark net
01:27
now in census dot io you can pinpoint devices that happen to be exposed to the Internet and are using back net. And what's interesting about this particular protocol is the fact that there are a lot of different things that are actually required for the protocol specifications.
01:46
So, for example, if you want to search very specific things,
01:49
you might want to look at the back net device I d. But the application software revision version
01:57
and you can actually find this using the first field that I listed in this table all the way down to I d support a time stamp that bite. My device might have the actual location where census that I will try to geo locate where the device is.
02:13
Um, any manufacturer information the description inside the metadata,
02:17
the product product type, the revision that may be listed in the metadata,
02:23
a model name, object name, and I d support. Also, uh, what named the vendor reported the name as and an official name
