  3. Project Overview: Context • 60 percent of all companies perceive an increased risk level due to new developments such as social networking, cloud computing, and personal devices in the enterprise.1 • Enterprises must proof trust to regulators, external business partners, and themselves. • Trustin data, networks, and clients is to a large extent an organizational and behavioral concept – and not so much a technical one. 1) Ernst & Young: Borderless security. Ernst & Young’s 2010 Global Information Security Survey . EYGM Limited, 2010.

  4. Project Overview: Goal Understand the security and trust properties companies want to have in their systems Understand how companies communicate these properties to the systems (if possible at all) and how companies then verify that the systems have the properties

  5. Project Overview: Scope Project Scope Mental model of systems’ trust relevant behavior Systems’ actual trust relevant behavior equivalent? Scope Today Human produces Trust evidence: enforces System Policy draws conclusions from Attestation produces Don‘t think of what is easy for the machine to do. Instead, let policy engineering be driven from what business users require and perceive.

  6. Project Overview: Expected Results • Analysis of requirements and constraints of business communities for policy engineering and trust evidence • Assessment of current practice (e.g. SELinux) and experimental approaches (e.g. Trust Distribution Diagrams) against the requirements • Example user studies

  7. Project Plan: Work Packages 1 Business & Organizational Needs 2 Trust Evidence Languages • Identify communities of real-world stakeholders: • Chief information security officers • Business analysts • Business process experts • Information security architects • Identify use cases • Conduct expert interviews, gather data • Prepare mini case studies • Identify sample languages for trust evidence • Current practice: • SELinux hooks • TCG attestation • Experimental approaches • Property-based attestation and semantic remote attestation • DTrace-based characterizations of run-time behavior • Trust distribution diagram (TDD) 3 Assessment of Effectiveness • Study effectiveness of these languages for these communities to talk about these trust properties • Identify future directions of research Legend: Focus of this presentation.
