Introduction to PC Security

Lesson 1

Introduction to PC Security

In this lesson, you will learn the facts and myths about PC security. By the end of the lesson, you will be able to assess your own risk, whether you're an individual or manage a network of any size. You will also perform a self-assessment to evaluate just how vulnerable you are to security flaws.

Your PC and Network

If you ever wondered what technical gurus are speaking about when they talk about LANs, WANs, VPNs, and P2P, you will find detailed answers in this lesson. Discover the basics of networks and how your PC connects to them.

PCs, Networks, and Software Demystified

Most people don't stop to think about how a Mac can talk to a PC and vice versa. Yet, different types of machines talk to each other on a daily basis across networks. They also talk to printers, fax machines, and a host of other devices. The OSI model for network connections lets you accomplish this, and you will learn all about it in this lesson.

Viruses, Worms, Blended Threats, and More

Get ready to investigate the world of viruses, worms, and blended threats. You'll learn what they are and the differences between all three. Of course, all this knowledge will also teach you how to protect yourself and your network from the hackers and crackers of the world.

The Family of Malware

This lesson introduces you to the ware family. What is the ware family? They are the products that download themselves onto your computer without your consent or knowledge—spyware, scumware, malware, and adware. You will meet them and learn all about where they live, places they frequent, and how to remove these unwelcome guests.

Exploits and Vulnerabilities

You may have heard of them: vulnerabilities, exploits, and exposure. But what are they? Have you ever wondered if someone really can control your computer without your knowledge? If you've been pondering these questions lately, then you will find your answers here, along with priceless information on protecting your computer and your network to keep your business and personal data private.

Network Attacks

Have you ever tried to access the web but received an error saying the page can't be displayed, you aren't connected, or you don't have access? Denial of Service attacks and SYN flooding are two types of network attacks that seem to go unnoticed on personal PCs and small networks. After this lesson, you will no longer be left wondering what happened to your Internet connection.

Everything You Wanted to Know About Firewalls (Part One)

This lesson will introduce you to firewalls. Join me in this lesson, and you will soon start building an impenetrable moat around your network.

Everything You Wanted to Know About Firewalls (Part Two)

Now that you have your moat built, it's time to arm up and defend yourself. In this lesson, you will learn how to configure your firewall and maximize your network security.

Laptops, Notebooks, Netbooks, and Wireless Networking

Laptops and wireless connectivity aren't as secure as they appear. You will understand why in this lesson.

Virtual Private Networking (VPN)

This lesson explores the Virtual Private Network and how it's different from standard networks, how it works, how to secure it, and how to set up your own. You can share files with family across the miles by allowing them to connect remotely to your designated shared folders. You can share music files, family pictures, and anything else you choose to give them access to.

Changing Face of Security

Now that you know what's out there, how can you possibly keep on top of security issues? There's so much information out there, how will you know what applies to you? You will learn about emerging security technology that will help make managing and securing your network easier. Finally, you can test yourself against the first security assessment to see how well you've secured your own PC or network.

Lesson 1
In our first lesson, you'll learn the facts--and the myths--about PC security. Then, I'll introduce you to the language of security and explain what you need to know about each acronym. By the end of this lesson, you'll also be able to assess your own risk, whether you're an individual or manage a network of any size. You'll also perform a self-assessment to evaluate just how vulnerable you are to security flaws.

Lesson 2
If you ever wondered what technical gurus are speaking about when they talk about LANs, WANs, VPNs, and P2P, you'll find detailed answers in this lesson. Discover the basics of networks and how your PC connects to them.

Lesson 3
Most of us don't stop to think about how a Mac can talk to a PC and vice versa. Yet, different types of machines talk to each other on a daily basis across networks. They also talk to printers, fax machines, and a host of other devices. The OSI model for network connections lets you accomplish this, and you'll learn all about it in this lesson. I'll also teach you how, why, and where the weak links of security are in software and operating systems.

Lesson 4
Get ready to investigate the world of viruses, worms, and blended threats. You'll learn what they are and the differences between all three. I'll also show you why people create them and where they come from. Of course, all this knowledge will also teach you how to protect yourself and your network from the hackers and crackers of the world.

Lesson 5
We’ll introduce you to the ware family in this lesson. Who is the ware family? They are the products that download themselves onto your computer without your consent or knowledge—spyware, scumware, malware, and adware. You'll meet them and learn all about their family traits and values. I'll also show you where they live, places they frequent, and how to remove these unwelcome guests that inhabit your PC.

Lesson 6
You may have heard of them: vulnerabilities, exploits, and exposure. But what are they? Have you ever wondered if someone really can control your computer without your knowledge? If you've been pondering these questions lately, then you'll find your answers here, along with priceless information on protecting your computer and your network to keep your business and personal data private.

Lesson 7
Have you ever tried to access the Web but received an error saying the page can't be displayed, you aren't connected, or you don't have access? If so, you may have been under an attack! Denial of Service attacks and SYN flooding are two types of network attacks that seem to go unnoticed on personal PCs and small networks. Why? Because beginners don't know what they are, why they're happening, or where they're coming from. After this lesson, you'll no longer be left wondering what happened to your Internet connection.

Lesson 8
This lesson will introduce you to firewalls. Join me in this lesson, and you'll soon start building an impenetrable moat around your network.

Lesson 9
Now that you have your moat built, it's time to arm up and defend yourself. In this lesson, you'll learn how to configure your firewall and maximize your network security.

Lesson 10
You may want to check out this lesson before you grab your laptop and run off to the next Internet café;, because what you learn today may surprise you! Laptops and wireless connectivity are the buzzwords of the moment, but these two technologies aren't as secure as they appear. You'll understand why in this lesson.

Lesson 11
I'm going to share my love for VPNs with you today. You'll learn what a Virtual Private Network is, how it's different from standard networks, how it works, how to secure it, and how to set up your own. Just think about the possibilities! You can share files with family across the miles by allowing them to connect remotely to your designated shared folders. You can share music files, family pictures, and anything else you choose to give them access to.
