>> Welcome back to the Cybrary course
00:00
in Building your InfoSec Lab.
00:00
I'm your host and Instructor, Kevin Hernandez.
00:00
In our last lesson, we looked at
00:00
the hardware required for building a lab,
00:00
most specifically the PC.
00:00
In today's lesson, we'll start looking at Smart Switch.
00:00
Lesson 4 smart switches and Virtual LANs.
00:00
Before were some looking into the hardware,
00:00
let's first talk about what is a VLAN.
00:00
A Virtual LAN,
00:00
it's basically a logical sub network.
00:00
Think about it like segregation.
00:00
The purpose of this and benefits,
00:00
it's basically efficiency of the network,
00:00
devices that will constantly talk to themselves.
00:00
You want to be happening in the little corner by
00:00
themselves that way it doesn't
00:00
bother the rest of the traffic.
00:00
Also, overall security up to network, you for example,
00:00
up here let's say,
00:00
baby monitor, network-based baby monitor.
00:00
You want to make sure that only authorized devices
00:00
access that network instead of anyone that's nearby.
00:00
Now, if you see the packaging is fairly simple.
00:00
You can actually bring some [inaudible] and
00:00
this is a clip in mechanism over here.
00:00
Basically if you look at this clip,
00:00
the clip that leads to where the cables are going to be.
00:00
If you, for example,
00:00
the cable, the little clip is on the front,
00:00
the cables will be more towards the front end or
00:00
[inaudible] a top end or to forward off to picture.
00:00
Well, in the other hand, if the clip isn't the bottom,
00:00
like in this picture,
00:00
the cables will tend to be more towards the wall.
00:00
That's why in my scenario
00:00
I ended up putting the cables towards the back.
00:00
Funny part about this switch is that even
00:00
though I perform send maps scan,
00:00
I was unable to find it at all.
00:00
I tried to connecting into it manually
00:00
following the instructions and
00:00
I wasn't able to find it, but here,
00:00
I'm able to actually downloading
00:00
the ProSAFE Plus configuration utility from the website.
00:00
I was able to finally detect
00:00
it and be able to configure it.
00:00
However, since I'm in subnets,
00:00
it does not allow me to manage it.
00:00
Now, if you're having issues or
00:00
your IP address and your
00:00
located on IP network are different,
00:00
it might be because you're looking at
00:00
your pre configure IP address,
00:00
not at the HTTP address.
00:00
If that's the case, you won't be able to
00:00
log in and make senior center switch.
00:00
I found this article on
00:00
the NETGEAR community which
00:00
will show you how to troubleshoot that.
00:00
Basically tells you is going to [inaudible] plug switch,
00:00
reconnect the plug switch.
00:00
Once you do that, you will be able to
00:00
access your switch you've configured.
00:00
Once logged in, you'll be able to see
00:00
a different information about
00:00
how your portrait being used.
00:00
You want to or enable the speed,
00:00
speed of area connected,
00:00
and over here, you can see the actual VLANs.
00:00
You can enable it based on ports,
00:00
and basically, once enabled,
00:00
you'll be able to see which VLAN to each group.
00:00
We'll be using this a lot,
00:00
wants we start configuring our firewall.
00:00
For the moment let's keep it disabled.
00:00
For the moment we'll keep this configuration disable.
00:00
The lesson we've taught the easier it is to troubleshoot.
00:00
Now what have you learned today?
00:00
Basically, you learned what is the VLAN.
00:00
Virtual LAN, its benefits,
00:00
which basically lets you group
00:00
together traffic that constantly talk to each other.
00:00
For example, cameras with their own server,
00:00
and it also add layers to that type of devices,
00:00
In this case, you don't want
00:00
anyone to access your baby monitor, although they knew.
00:00
Also, we look at the hardware LAN,
00:00
regardless of being a Smart switch,
00:00
like the one I just shown you,
00:00
are built-in features within your router.
