The FITNESS (Fault and Intrusion Tolerant NEtworked SystemS) Research Group operates at the University of Naples “Parthenope”, Department for Technologies, and performs cutting-edge research in distributed systems security and dependability in general, and in Critical Infrastructure Protection in particular.
Combining intrusion and fault tolerance is an effective approach to handle security and reliability issues and has attracted significant research interest. In meeting security and reliability requirements, however, existing solutions often sacrifice performance, a loss that is not acceptable for many critical applications (e.g., e-commerce, e-procurement). Also, most of the security mechanisms proposed are purely software based, which simplifies design and implementation but reduces resilience to security attacks. The thrust of our current work is to develop methods, technologies, and tools for building networked systems which can tolerate both accidental and malicious faults yet providing high performance.
