Abstract: The purpose of this thesis is twofold. In the first place it presents a comparative study of the advantages and drawbacks of several approaches to insure software safety and security. It then focuses more particularly on combining static analyses and dynamic monitoring in order to produce a more powerful security architecture. The first chapters of the thesis present an analytical review of the various static, dynamic and hybrid approaches that can be used to secure a potentially malicious code. The advantages and drawbacks of each approach are thereby analyzed and the field of security properties that can be enforced by using it are identified. The thesis then focuses on the possibility of combining static and dynamic analysis through a new hybrid approach. This approach consists in a code instrumentation, that only alters those parts of a program where it is necessary to do so to insure the respect of a user-defined security policy expressed in a set of modal μ-calculus properties. this instrumentation is guided by a static analysis based on a type and effect system. The effects represent the accesses made to pretested system ressources.
