Hello and welcome to this course titled Getting Personal with WPA3 Wi
-Fi Security. My name is Keith Bogart and I will be the instructor for
the duration of this course.
Let's talk about some key concepts that this course is going to cover
at a high level, then we'll drill down a little bit deeper into some more
specific concepts.
So number one, you're going to learn about Wi-Fi key management and cryptographic
foundations. You're going to learn there's a whole bunch of different
Wi-Fi keys used for different things and how they are derived from each
other and some of the formulas and algorithms used to derive those keys.
We're going to talk about the evolution of Wi-Fi security protocols from
WPA2 to WPA3. Now we're not going to spend really a lot of time on the
mechanics of WPA2.
If you watch my jumping into Wi-Fi security course, I already go into
that in pretty good detail, but we'll do a quick glossing over of WPA2
so that when we do get into WPA3, which is the majority of this course,
you'll understand why WPA3 is so much stronger and so much better.
We'll also look at how to protect management and open network communications,
as well as a whole bunch of WPA3 enhancements.
So what are some of the major topics we're going to look at?
Number one, we're going to look at the role and hierarchy of keys in Wi
-Fi security. There are keys that derive other keys that derive other keys
until you finally get to the keys you actually use to encrypt and decrypt
data, provide your data integrity.
So we're going to look at what their names are, where they come from,
and how one is derived from the other.
So we'll look at the pairwise key generation.
You may have heard of things like pairwise master key, pairwise temporal
key. We'll talk about what does that word pairwise mean and what do these
things have to do with security?
We'll look at the cryptographic derivation and handshake mechanics.
There's a lot of different mechanisms for creating keys depending on what
feature you're using, whether it's just be a plain old WPA3 SAE connection,
whether using Wi-Fi easy connect, the opportunistic wireless encryption
standard. We'll talk about those.
We'll talk about the transition from WPA2 to WPA3 and the rise of SAE
and how you can protect your management frames and prevent spoofing.
We'll talk about some features where we can protect our authentication
frames, our disassociation frames, our action frames so that somebody
can't insert a rogue access point into our network and wreak havoc.
We'll also talk about some E and DPP.
So let's talk about some learning outcomes I hope you can have after going
through this course.
I want you at the end of it to be able to explain the complete Wi-Fi key
hierarchy and its functions.
I want you to be able to differentiate between WPA2 pre-shared key and
WPA3 simultaneous authentication of equals key derivation processes.
We will analyze the importance and operation of WPA3 protected management
frames and beacon protection so that you can explain that to other people
and explain why it's such a good thing.
And hopefully you'll be able to configure and validate modern Wi-Fi security
enhancements such as Wi-Fi easy connect and opportunistic wireless encryption.
So there are a few prerequisites for you to really maximize and get the
most out of this course.
I'm assuming you already have some familiarity with basic 802.11 wireless
LAN terminology.
If I say things like SSID, like authentication frame, association frame,
I'm hoping you already know what those things mean.
Also, hopefully you have some experience connecting to WPA2 and WPA3 wireless
LANs. And you have some general familiarity with cryptographic hashing
functionality. In other words, if you don't know what a cryptographic
hash means, you might not know the mechanics of how it works.
But just that term, you should know what is a cryptographic hash and what
are some examples of why we use them?
What's the benefit of using them?
Hopefully you know that.
If not, just take five minutes go on chat GPT and ask it, what is a cryptographic
hash and why would I benefit from it?
So with that, let's go and start our course and hopefully you'll get a
