SeSaR: Security for Safety

Abstract

The SeSaR (Security for Safety in Railways) project is a HW/SW system conceived to protect critical infrastructures against cyber threats - both deliberate and accidental – arising from misuse actions operated by personnel from outside or inside the organization, or from automated malware programs (viruses, worms and spyware). SeSaR’s main objective is to strengthen the security aspects of a complex system exposed to possible attacks or to malicious intents. The innovative aspects of SeSaR are manifold: it is a non-invasive and multi-layer defense system, which subjects different levels and areas of computer security to its checks and it is a reliable and trusted defense system, implementing the functionality of Trusted Computing. SeSaR is an important step since it applies to different sectors and appropriately responds to the more and more predominant presence of interconnected networks, of commercial systems with heterogeneous software components and of the potential threats and vulnerabilities that they introduce.
