How secure is your computer right now? Computers and the Internet have revolutionized our world, but if you’re like most people, you have no clue how they work or what the real threats are. While there are tons of resources on cybersecurity for technology experts, there are very few for average computer users. That’s where this course comes in. The instructor will explain the basics of computers, the Internet, security, and privacy—in plain English, using simple analogies—and then show you basic steps to keep your computer secure. The course will cover: an overview of cybersecurity, how the Internet and encryption work, passwords, computer and network security, online privacy, safe Web surfing, secure communication, and mobile security. Optional reading and activities will be available in the recommended textbook. The course includes eight lectures and two sessions of optional "office hours." During office hours, students can receive individual help and/or ask detailed questions. | Lecture + Q&A.
