This week is a crash coruse in information security. I discuss what security means and summarize various types of threats to operating systems and networks. Here is a pdf version of the slides featured in the video. Remember to watch the lecture at your own pace by rewinding or fast forwarding as needed.

Questions & Exercises

Some of these questions will be on the next quiz. Remember the answers are in the back of the book.

Additional Clips (recommended)

Now would be a good time to finish watching Code.org's series on How The Internet Works. Video #6 explains 256-bit encryption and information security on the Internet, including public and private keys. Video #7 summarizes the most common types of cybercrime including viruses, DDOS attacks, and phishing scams.
