Each iOS application runs in a separate virtual machine, or sandbox, and applications may also be subjected to dynamic analysis, or fuzzing, whereby illegal input is intentionally applied to an application so as to test for security issues. Return oriented programming may also be used in attempts to reveal certain application vulnerabilities, and devices may be jailbroken so as to make them more open to developers who can then better evaluate system security. In this course, you will learn about sandboxes and how to initialize them, how to secure iOS applications and devices for enterprise, how to design and administer fuzz tests on iOS applications, how to defend applications against exploits, how to use return-oriented programming to reveal application vulnerabilities, and how to install and use jailbreaking tools on iOS devices.

Target Audience
Application developers on the beginner and intermediate level seeking to create and deploy secure iOS applications
