Android
Our Android workshop aims to provide an insight into every aspect of secure mobile application development. In order to cover everything a developer needs to commit and publish secure code through the Play Store, the agenda is built from the ground up and has been designed to provide practical exercises throughout the entire training, with a heavy focus on how Android as a development platform offers security features to developers.
After a short introduction, we take a look at the overall Google/Android philosophy, the OS security features and their implications on the daily life of a developer. We take a look at typical issues in Android applications with some now-infamous bugs and exploits from the past, how problematic challenges can be tackled and how typical pitfalls can be avoided. Throughout the course, a plethora of in-house demo applications are provided to highlight issues.
The 'Mobile security baseline' module can be taken as general preps to this course. While the 'Mobile testing automation' module greatly extends the coverage of the practical field.
The course has been tested and used successfully with several mobile heavy developer companies.
