About this unit
This unit introduces the concept of PII and the ways in which PII and other data can be tracked online (cookies, search history, browsing history, geolocation). Learn how attackers can gain access to data and devices with phishing, rogue access points, and malware, and see how you can protect yourself with encryption, secure protocols, strong passwords, and multifactor authentication. With more than 100 questions, you can practice what you've learned and study for the AP Computer Science Principles exam.
