Android Java and Native Code Security

 

Android is an open platform for mobile devices such as handsets and tablets. It has a large variety of security features to make developing secure software easier; however, it is also missing certain security aspects that are present in other hand-held platforms. The course gives a comprehensive overview of these features, and points out the most critical shortcomings to be aware of related to the underlying Linux, the file system and the environment in general, as well as regarding using permissions and other Android software development components.

 

Typical security pitfalls and vulnerabilities are described both for native code and Java applications, along with recommendations and best practices to avoid and mitigate them. In case of native code applications we go into more details, discussing memory management related issues, protection techniques as well as their circumvention (such as Return Oriented Programming). Finally, the most important cryptographic algorithms in symmetric cryptography, hashing, asymmetric cryptography and PKI are also discussed and put into the context of Android.

 

In many cases discussed issues are supported with real-life examples and case studies. Finally, we give a brief overview on how to use security testing tools to reveal any programming bugs.
