Abstract

JOANA is a tool for software security analysis, checking up to 100 kLOC of full multi-threaded Java. JOANA is based on sophisticated program analysis techniques and thus very precise. It includes a new algorithm guaranteeing probabilistic noninterference, named RLSOD. JOANA needs few annotations and has a nice GUI. The tool is open source and was applied in several case studies. The article presents an overview of JOANA and its underlying technology.

Abstract

The invasive computing paradigm offers applications the possibility to dynamically spread their computation in a multicore/multiprocessor system in a resource-aware way. If applications are assumed to act maliciously, many security problems arise. In this acticle, we discuss different ways to deal with security problems in a resource-aware way. We first formalize the attacker model and the different security requirements that applications may have in multi-core systems. We then survey different hardware and software security mechanisms that can be dynamically configured to guarantee security on demand for invasive applications.
