How secure is your computer right now? You probably don’t know. Computers and the Internet have revolutionized the modern world, but if you’re like most people, you have no clue how they work or what the real threats are. It’s not your fault. While there are tons of resources on “cybersecurity” for technically savvy people, there are almost none for regular, everyday folks. That’s where this course comes in. The instructor will explain the basics of computers, networking, security, and privacy—in plain English, using simple analogies—and then will show what can be done at home to make your computer (Mac or Windows) and even mobile devices (iPhone or Android) more secure. There will be optional reading and activities using the recommended textbook. There will be six sessions of lecture and three sessions of “office hours” (alternating with lecture) when students can receive one-on-one help using their own devices.
