Security-Oriented Analysis of Application Programs (SOAAP)

Sandboxing technologies such as Capsicum and CHERI support the fine-grained compartmentalisation of large-scale applications such as web browsers and office suites, as well as multiple-component software such as the UNIX userspace. When deployed correctly, application compartmentalisation offers significant benefits by allowing policies to be imposed within applications, and in mitigating exploited vulnerabilities. However, application compartmentalisation remains an art rather than a science: identifying, implementing, and debugging partitioning strategies requires detailed expertise in both the application and security. SOAAP is exploring semi-automated techniques, grounded in static analysis, dynamic analysis, and automated program transformation, to improve the developer experience. This project is jointly funded by Google and DARPA, and takes place within the context of the CTSRD project.
