Is there such a thing as a good hacker? We’ll explore that question in today’s lesson about hackers and hacking. This lecture is the first in a twelve part series about information security. But in many ways, this lesson provides the motivation for all the other ones.

Section 1: My First Section

Last time we focused on hackers and what motivates them to break into computer systems. This time we’re going to dig deeper into how hackers hack.

This lesson focuses on how to create security controls in the ever-changing world of information technology.



In this lesson we consider the technical means by which data can be kept secret. Our topic this time is cryptography, the science of encryption.

Any information security technology needs to distinguish between those who are authorized and those who are not authorized to access the data. Strong Locks and keys that even the owner does not understand or remember are not very useful for security systems! Likewise, if a lock is easy to open, it wouldn’t be much of a security system either. The foundation of that authentication process is called identity. To gain access on a computer system depends on your identity. But how does the system really know who you are? Some sort of proof will be required, and such proof is called authentication. Identity and authentication systems are the topic of this lesson.

Any security system effectively has to ask the question “who goes there?” in order to get the job done. Even when your messages travel to the far ends of the Internet, the receiving party needs some way to verify who really sent the message. User names and passwords are fairly easily intercepted and spoofed. There needs to be stronger ways to verify that a message is what it claims to be and that the sender is authentic. In this lesson we can learn about two of these technologies. First let’s examine digital signatures and digital certificates.

In this lesson we are going to be learning about Firewalls.

In this lesson, we’ll peer into cloud computing in a way that will make the cloud a little less mysterious. We’ll learn that resource sharing – servers, storage, applications, and bandwidth – is one of the defining elements of cloud computing. But with such resource sharing comes with security concerns.

Devry University


Up until now we’ve only considered preventative controls. But no control can prevent every type of attack. So beyond preventative controls, we also need controls that detect and correct. Two such controls are called Intrusion Detection Systems and Intrusion Prevention Systems.

In this lesson we are going to learn the process for incident response.

In this lesson we can learn how contingency planning can help an organization prepare for the worst disasters when they strike.

Devry University


In this final lesson, we’re going to put into practice everything we have studied so far. You will have a chance to draft your own information security plan, guarding data that is valuable to you. If you desire, you can make your plans realistic and apply them to an actual business, personal, or organizational situation. Or, if you prefer, you can make your plans fanciful and make a game out of the activity. Either way, you will get a chance to experience one type of planning exercise that is commonly practiced by information security professionals.
