1. Self-healing Architectures based on context DEpendent adaptive Software Agents (SADESA) – an extension of EU-IST Project SAFEGUARD DeSIRE Workshop Pisa, 25-26 November 2002 Sandro Bologna, ENEA bologna@casaccia.enea.it WWW.IST-SAFEGUARD.ORG

2. Safeguard Project Presentation - November 2002 Pisa An overview of the SAFEGUARD Project Aims to enhance the survivability of Large Complex Critical Infrastructures (LCCIs) developing a middleware that implement the concepts of Self-healing Architectures. It will use electricity networks and telecommunications networks as practical examples of LCCIs. The aim is to produce a generic solution that can be adapted for other forms of LCCI. Started December 2001, ends May 2004

3. Safeguard Project Presentation - November 2002 Pisa Assumptions in the SAFEGUARD Project Safeguard is based on the assumptions that: Large Complex Critical Infrastructures are too complex to be protected solely by the existing generic SCADA Systems based on “conventional” technology LCCIs does not evolve dynamically Agent technology is a very effective way to implement the concepts of Self-healing Architectures and increase the survivability of LCCIs faced with: Failure Accidents Attacks
