Now that you have a good understanding of encryption, you can build on that foundation by learning additional ways to protect user data.

14 videos  //  141 minutes of training

Course description

In addition to encryption, there are a number of other mechanisms you can employ to protect data. In this course you will learn about common risks to data, how to protect files, how ensure that data is transmitted over a network securely, and how to protect data from inadvertent leakage. You will also learn how to authenticate your app to an online data source, and how to use good design, code, and iOS features to ensure that processes do not interfere with each other, causing unexpected results.
