Reliably Secure Software Systems (RS³)

The Priority Programme at a Glance

Motivation

This Priority Programme assumes that a paradigm shift in IT-security is necessary in order to reliably guarantee the security of complex software systems. The current trust-based and mechanism-centric approaches to IT-security shall be complemented by property-oriented solutions. This paradigm shift shall enable a trustworthy certification of system-wide, technical security guarantees that adequately respects the semantics of programs and of security requirements. Bridging the gap from security in-the-small to security in-the-large will involve the improvement of conceptual foundations, the development of analysis and engineering tools, and their migration into practice. Collaborations between multiple sub-disciplines of Computer Science, primarily formal methods, IT-security, and programming languages, will be necessary to achieve the objectives of the programme.

The three RS³ Guiding Themes

The first guiding theme is the development of precisely defined (and, thus, verifiable) security properties. This shall enable a property-oriented perspective on security that, on the one hand side, abstracts from technical details of implementations and, on the other hand side, permits one to model the manifold security requirements and guarantees in an adequate and precise way.

The second guiding theme is the development of program analysis methods and tools that target the verification of security properties in a sound, precise, scalable, and usable way. This will create the basis for a semantically substantiated (and, thus, reliable) certification of security guarantees for software systems. Verification tools will be employed to establish security properties of programs as well as to ensure the soundness of security analysis tools.

The third guiding theme is the development of concepts for understanding and certifying security aspects even in complex software systems (hence, for security in-the-large). This requires the adaptation of established techniques for abstraction, decomposition and step-wise refinement to the field of security. In particular, it shall become possible to derive abstract security guarantees (e.g., need-to-know or separation-of-duty) from the low-level properties that are typically guaranteed by security mechanisms.

The overall goal of the programme is to support the reliable certification of useful, system-wide security guarantees based on a well-founded understanding of programs and of security aspects. The programme is designed to run for six years.
