  3. Télécom Paris – At a Glance … • French Premier School of Information Sciences and Technologies • Established in 1878 • Four Departments: • Networks and Computer Sciences • Electronics and Communications • Image and Signal Processing • Economy, Management, Humanities and Social Sciences • Statistics of the year 2003 • Total Budget of 45 Million Euros • 142 Academics, 241 PhD students, 1270 Internees • 270 Revues, 550 Conferences • 41 Projects, 16 Softwares, 14 Patents Computing in High Energy Physics 2004 (CHEP'04), Interlaken - Switzerland

  4. Formal Security Evaluation: Why? • Independent (third party) attestation of a developer’s security claims against a defined security evaluation criteria. • Evaluations result in independent measure of assurance, therefore build confidence in security. • Secures development process and yields better product. • Comprehensive security solutions cannot be evaluated by simple examination!

  5. Evolution of Evaluations Criteria TCSEC Canadian Criteria 1985 1993 UK CLs 1989 German Criteria Federal Criteria Draft 1993 French Criteria ITSEC 1991 v1.0 1996 v2.0 1998 Dutch Criteria Computing in High Energy Physics 2004 (CHEP'04), Interlaken - Switzerland

  6. CC for Grid Security Architecture • Both CC and Computational Grids have emerged by the late 1990s. • However, the Grid community lacks experience in the exercise of CC! • Perhaps, because security features were overlooked in the early Grid endeavors … • The growing size and profile of Grid oblige its designers to incorporate adequate security solutions. • The assessment of these solutions require excellent evaluation criteria. • CC has all the merits of such criteria  Computing in High Energy Physics 2004 (CHEP'04), Interlaken - Switzerland

  10. CC Evaluation of Health Grid SA Target of Evaluation (TOE) HEALTH GRID independent of the applications being run over it. TOE Security Environment • Assets:Data and information across the TOE, applications running over the TOE, computing resources constituting the TOE, storage repositories of the TOE, communication links (wired and/or wireless) within the TOE.

  11. CC Evaluation of Health Grid SA TOE Security Environment • Assumptions:A small community of active users (A.ActiveUsers), a large community of public users (A.PublicUsers), and a provision of periodic revision of the security architecture (A.TechnologyUpdates). • Threats: Threats to Information (T.I), Threats to Resources (T.R) Computing in High Energy Physics 2004 (CHEP'04), Interlaken - Switzerland

  17. Conclusions • As Grid technology becomes more widely adopted, the need for security will increase even more. • The need to protect privacy and security of priceless data over the Grid is fueling even more need for common security evaluation criteria. • It is imperative for the Grid community to exercise some formal evaluation mechanism for the Grid security solutions. • CC can play a vital role for the evaluation of Grid security solutions.
