Simulation of activities and attacks : application to cyberdefense

Abstract : The concern over the security of the infrastructure of a company is only growing deeper and became a source of worries for companies. They use different systems to detect and deal with attack but those systems are usually made to detect one type only of the two main type of attack: attacks made to target the largest amount of people possible. Targeted attacks are rarer but more dangerous as it penetrates deep into a system and are very specifics. However the systems used to deal with it are proved of limited efficiency. Even when they send alerts and news to the operator, there is just to much information going along with it making the often ill-trained operators unable to react and overwhelm by massive information. The goal of this thesis is to create a tool that would help to form operator but also help to test more efficiently security systems. We'll approach the problem by first emulating the infrastructure and services of a small company with its different users and services. It will be use to create the data of the regular operations and interactions of a company during normal activity but also under attack. Once the system is emulated and we collected the necessary data, we will start to simulate the system according to what we need the simulation for. This simulation would need less resources than the emulation and will be scalable and capable to be dynamically change according to the needs. The aim is to have a light tool capable to simulate different behaviors and different type of realist simulation of a system to help improve the formation of operators and also test security devices more fully. The whole would be supervised by a console of control of the simulation who will receive the information of the simulated elements and the simulated operator console. It would have the capacity to create incidents and problems into the systems along with attacks.
