Course description

No study of secure application development would be complete without also understanding how to protect your code and the platform it runs on. In this final course, you will consider the risks of integrating code you did not write into your app. You will learn how to handle and log errors generated within your app. You will also learn about the many types of tests your app should go through before it is released to users. You will see the risks of running your app on a rooted device, and how your app can detect if it has been installed on such a device. You will learn about the risks of reverse engineering and how to protect your app from tampering. You will also learn a little more about the risks social engineering poses to your users. Finally, you will learn where to go to continue your security education and finish up with a review of key points from this path.
