1) HARD PROBLEM(S) ADDRESSED (with short descriptions)
This refers to Hard Problems, released November 2012.

By leveraging approaches to software architecture we will be able to better understand the security implications of frameworks used to build many of today's mobile software systems. This will allow us and provide tools and techniques for building more scalable and composable frameworks that have security assurances that can be verified statically, can be used for building self-securing resllient systems, and that ultimately reduce security vulnerabilities in frameworks and applications based on them in practice.

3) KEY HIGHLIGHTS

We have transitioned the first draft of an Android architectural style focused on capturing and analyzing security properties (both statically and dynamically) to GMU. We are working with them to integrate our two approaches to have a standard model for information from static analysis of Android systems and run-time monitoring and mitigation.

Completed an initial implementation including the user interface and small-scale evaluation of an inference algorithm for iteratively and interactively refining a global hierarchical graph while maintaining its soundness, thus tackling the scalability hard problem associated with using the Scoria approach.

Completed a data-driven approach that uses code patterns identified by visitors and metrics to identify systems where the abstract runtime structure is significantly different from the code structure, thus making more complex reasoning about runtime properties such as security.
