課程 3（共 4 門，Specialization Introduction to Cyber Security）

This course introduces real-time cyber security techniques and methods in the context of the TCP/IP protocol suites. Explanation of some basic TCP/IP security hacks is used to introduce the need for network security solutions such as stateless and stateful firewalls. Learners will be introduced to the techniques used to design and configure firewall solutions such as packet filters and proxies to protect enterprise assets. Perimeter solutions such as firewalls and intrusion prevention systems are shown to have significant drawbacks in common enterprise environments. The result of such weakness is shown to often exist as advanced persistent threats (APTs) from nation-state actors. Such attacks, as well as DDOS and third-party attacks, are shown to have potential solutions for modern enterprise.

Hi everyone, Ed Amoroso here, and what I'd like to do in this video is I

want to kind of wrap up this course, this topic of real time cyber security.

If you've been with us, we started by looking at firewalls and packet

filtering and how you arrange them and do IPS and all kinds of real time things.

Looked at SYNs, we looked at Socks, we had a lot of fun with that,

very interesting stuff.

But if you're wondering, what's the full range of controls that need to be

done to kind of protect a typical enterprise?

Well, that's a tough question, this is a really complex and very full topic.

We probably would need 1,000 videos to really dig into all of these things

properly.

But one of the things I worked on personally that you can download,

we're going to pop up the URL, it's tag-cyber.com.

You can download a free PDF.

It's three volumes that we've downloaded and created.

You'll see the information.

But one of the graphics in my reports

is the graphic that I'm showing here on the screen.

It shows basically six columns of categories of different types of controls.

And under each one, I sort of label out the control category that I think

needs to be attended to from a cyber security perspective,

if you're protecting infrastructure.

And you can see intrusion detection prevention, you can see firewall,

you can see a lot of the things that are probably very familiar to you.

There may be a couple in there that you're less familiar with,

like unified threat management as a category.

We didn't have a lot of time for

as we went through our discussion of real time cyber security.

It's basically combining a lot of different security controls into

one appliance or device that a small company would use.

But you may want to take a little time if you feel like you really want to do more

research and dig in and

get a better general sense of all the different controls that are here.

You may want to take a look at this graphic,

you might want to think about downloading the PDF.

It might just give you something,

a frame of reference as you plan a life time of learning in this area.

You can sort of number them, there's 50 different areas that I've identified.

And I think in each of them,

you can spend some time making sure that you get yourself comfortable.

It's kind of a self-learning sort of thing that you can do outside the confines of

your learning in this course.

But if you're really, really motivated, and you say I want to become an expert,

then grabbing this this diagram and going

through the different components that are in here might be very useful to you.

So I hope you've enjoyed this discussion of real time cyber security.

I hope it's really helped you, and I've enjoyed my time with you here

as we've gone through real time cyber security, thanks.
