Information Security Concepts

This is Chapter 7 of the forthcoming book Computing Concepts for Information Technology. It is an overview of information security concepts and terminology, written for college undergraduates who will later take a full-semester course in information security. It is suitable for anyone who may want a quick overview of the concepts and terminology.

PDF ePub mobi

For iPad or iPhone, download the ePub file and choose “Copy to Books.”

If you have a Kindle reader or Kindle app, you can download the mobi file and send it to your Kindle library. If you don’t want to jump through those hoops, you can actually buy this chapter from Amazon. It’ll cost you 99¢ because that’s the lowest price Amazon allows and I’ll get 35¢ of that. I promise not to spend it all in one place. Note well: There is nothing in the Amazon chapter that’s not in the free files above. The only reason to spend money is to avoid a small amount of hassle getting the chapter into your Kindle.

For Android, you should be able to download the ePub file and choose “Upload to Google Play Books” as the file disposition. I’ve had trouble with that; what worked for me was to download the ePub file to a desktop or laptop computer, in a web browser go to, log in if necessary, choose “Upload Files,” and upload the ePub file. That makes it available on all your Android devices. You can alse use the Kindle app or another ePub reader app.
