Abstract: The security of telecommunications infrastructures is a major issue for satisfied it in terms of confidentiality, integrity, availability and in terms of quality of services (QoS) and it is difficult to guarantee the availability of these critical infrastructures (CIs) 24 hours a day. They present the vulnerabilities and a failure in one CI can impact to another CI to cause service disruptions. In this purpose, we propose a new approach of multi-level criticality to better assess and monitor CIs and their interdependencies in order to predict possible risks for increasing security. This paper proposes CI security modelling for trust components and interdependencies based on multi-levels of criticality, which are added to the security of IP multimedia subsystem (IMS) components to reduce its impacts and improve its resilience in order to prioritise risks according to several levels of criticality. The proposed approach is based on Totel model and implicative interdependency model (IIM).
