This paper studied the security assessment mechanism of strategy to system flexibility based on Embedded Real-time System.To deal with the problem that embedded system can not dynamicly get security situation and respond when system is running,strategy to system flexibility based on embedded real-time system was proposed to improve the system security.And the security assessment module based on pattern matching was designed and realized,which achieved dynamic real-time evaluation of system security and provided a decision support for the system dynamic configuration of security strategies.Simulation evaluation environment based on RT-Linux was established to test the safety performance of the security assessment system.Test results show that the overhead of security assessment module is very small,can effectively protect the safe operation of embedded real-time system,and has wide application value and prospects.
