| 摘 要： | 针对高安全级别信息系统提出一种利用策略和审计日志信息进行态势感知的安全态势感知模型。相比传统通过入侵检测系统采集网络数据和系统数据进行分析的方法，该模型对于威胁事件有较强的灵敏度，能够在系统发生威胁事件的第一时间觉察。同时模型依托可信计算技术，使整个系统运行在允许范围内，有效提升系统防护能力，对高安全级别信息系统的安全监控有实际意义。

| Abstract: | This paper proposes a security situational awareness model for situational awareness using policy and audit log information for high security level information systems. Compared with the traditional method of collecting network data and system data through intrusion detection system， the model has strong sensitivity to threat events and can be detected in the first time when a threat event occurs in the system. At the same time， the model uses trusted computing technology to make the whole system operate within the allowable range， effectively improving the system protection capability， and it has practical significance for the security monitoring of high security level information systems. |
