The paper presents a qualitative approach to analyze the security and survivability of Intelligent Transportation System (ITS) networks. The analysis identifies threat mitigation strategies for each threat identified and provides suggestions for improved security and survivability. The proposed approach could be applied during the planning and design phase of new ITS projects to evaluate different design alternatives or to assess the vulnerability and survivability of an existing ITS systems. The paper presents the results of a phone survey conducted to identify the normal usage scenarios and possible attack scenarios and their impact on traffic management centers (TMC) operations. The paper also presents a summary of the security and survivability analysis conducted during the planning and design phases for the City of Moscow ITS signal integration project. The analysis identified attack scenarios and threats, threat mitigation and survivability map with improved or additional threat mitigation strategies for different design alternatives. The proposed approach provides a significant addition to the current design practices of ITS systems by integration system security and survivability in the design process. A cost-benefit analysis of the proposed mitigation strategies should provide transportation officials with a decision making tool to evaluate different design alternatives and to improve the overall survivability of ITS systems.
