Security Evaluation of Power Communication System Based on SSE-CMM

SSE-CMM is a method to measure the practical ability of safety engineering. Its goal is to develop safety engineering into a set of meaningful, mature and reliable disciplines. In this paper, the system security engineering capability maturity model (sse-cm) is introduced into the research of security evaluation of power communication network, and the model is appropriately tailored according to the actual situation of power communication network, so as to enhance its applicability and operability. The preliminary work of this research is to be familiar with SSE-CMM and relevant standards, formulate safety assessment form and complete other necessary preparations: complete questionnaire survey, fill in assessment form, collect data and evidence in the on-site stage; The later work is to develop the scoring process, generate the evaluation report and analyze the algorithm. The probability distribution table of system failure risk obtained by example analysis reveals the objective inaccuracy in the process of risk prediction.
