Protection obligatoire répartie : usage pour le calcul intensif et les postes de travail

Abstract : This thesis deals with two major issues in the computer security field. The first is enhancing the security of Linux systems for scientific computation, the second is the protection of Windows workstations. In order to strengthen the security and measure the performances, we offer a common method for the distributed observation of system calls. It relies on reference monitors to ensure confidentiality and integrity. Our solution uses specific high performance computing technologies to lower the communication latencies between the SELinux and PIGA monitors. Benchmarks study the integration of these distributed monitors in the scientific computation. Regarding workstation security, we propose a new reference monitor implementing state of the art protection models from Linux and simplifying administration. We present how to use our monitor to analyze the behavior of malware. This analysis enables an advanced protection to prevent attack scenarii in an optimistic manner. Thus, security is enforced while allowing legitimate activities.
