How secure is your computer right now? My guess is that 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 these things work or what the real threats are. It’s not your fault. Where would you have learned about this? While there are tons of resources on ‘cybersecurity’ for people that already understand computers and networking, 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 you can do at home to make your computer (Mac or Windows) and even mobile devices (iPhone or Android) more secure! Optional reading and activities using the recommended textbook. Lecture (plus questions).
