In this section of the course I'm going to show you how to hack
now before we get started.
Please note you don't have to learn Kelly Linux for the CCMA exam.
But in this section I'm gonna show you practically how to hack networks using Kelly or colleague Isla
Nix if you prefer.
I think you're going to learn a lot more and understand a lot more if I practically demonstrate man
in the middle attacks rogue DHB service denial of service attacks and various other attacks practically
using Kelly Linux.
So rather than just talking about this rather than just showing you pictures or PowerPoint slides I'm
going to show you practically how you can hack networks very very easily.
We're going to start with some basic attacks.
We're going to send DDP messages into a network and make sure that our Kelly linux host and former trunk
with a switch we're going to send BP to use into the network to make sure that our Kelly linux host
becomes the spending tree root.
Show you a whole bunch of attacks.
It's really important that you lock down networks.
It's really important that you configure your networks properly to stop these kind of attacks.
Now if you're studying for the CCMA exam make sure that you understand the principles of security make
sure that you understand that we need to teach users or non-technical people that they shouldn't simply
open up an email.
So if someone sends them an email saying you need to click on this link we need to teach people not
to do that.
That's a classic phishing attack.
So an attacker will send an email to someone in your organization saying click on this link for instance
to see a really cute picture of a cat or video of a cat or something.
If someone clicks on that it takes them to a dodgy Web site which allows an attacker to take remote
control of a user's P.C. make sure that you educate your users so that they know they shouldn't just
click on any email.
I have this kind of problem at home as an example.
My wife is not technical.
My kids are young.
I need to teach them not to simply just go to any Web site because they could get into trouble.
Don't just open any email attachment you need to educate users which could be your family could be an
enterprise that they shouldn't just open attachments.
They shouldn't just go to any Web site.
Now again in the section I'm going to show you various types of attacks you don't have to learn Kelly
Linux for the exam but understand the principles and understand very importantly how to implement DTP
snooping and dynamic OP inspection.
If you're short of time watch the dynamic OP inspection video watch the DHB snooping video.
Those are the most important videos.
Make sure that you understand the Cisco configuration of how to stop attacks.
Port security options like that you don't have to learn how to attack.
You need to learn how to protect networks.
Okay so let's get started.
And I'm gonna show you how to attack networks using Kelly Linux.
