| 摘 要： | 很多网关系统和入侵检测系统被设计来保护信息系统的安全，其中一种安全隐患是现有网关系统的不完备性和入侵检测系统的虚警和漏警。该文总结了前人成果，改进了原有的入侵检测算法，提出了一个基于改进贝叶斯算法的新模型。该模型提高了入侵检测系统的完备性和准确性，更有效地保障了信息系统的安全。

| Abstract: | Although various gateway and intrusion detection system have been designed to protect system security, they work with a hidden trouble on the imperfectness of gateway and the error diagnosis of intrusion detection system. The paper improves the algorithm of intrusion detection system and provides a new security model based on Bayes algorithm. This model improves performance of intrusion detection system and protects the security of information system more effectively. |
