1. Managing Cyber-Identity, Authorization and Trust (and their inter-relationships) Prof. Ravi Sandhu Laboratory for Information Security Technology George Mason University www.list.gmu.edu sandhu@gmu.edu

2. 2 Problem Drivers and Consequences PROBLEM DRIVERS Uncertain threat: We always fight the last war Technological change: B2B integration, Pervasive (ubiquitous) computing, Peer-to-peer, grid and utility computing, Intels LaGrande and Microsofts Longhorn, the next Intel, Microsoft, Cisco, … Business change: Outsourcing/globalization, Cost/ROI, federated identity (relying party is NOT the identity provider), identity grades (identity vetting, authentication strength, purpose, privacy all vary) CONSEQUENCES The 3-decade old problem of managing identity, authorization and trust is rapidly becoming more difficult, challenging and essential Real progress requires radical shifts in our approach and fundamental advances in basic research

3. 3 Radical Shifts: get real Focus on what needs to be done rather than how it is to be done real-word business requirements rather than hypothetical academic scenarios the 80% problem rather than the 120% problem soft and informal rather than hard and formal constructing the policy rather than auditing the policy constructive safety via policy articulation and evolution rather than post-facto algorithmic safety ordinary consumers as end-users and administrators rather than techno-geeks or math-geeks

4. 4 Radical Shifts: good enough beats perfect EASY SECURE COST Security geeksReal-world users System owner
