摘要： An intrusion detection system and method for a computer network includes a processor and one or more programs that run on the processor for application inspection of data packets traversing the computer network. The one or more programs also obtaining attribute information from the packets specific to a particular application and comparing the attribute information against a knowledge database that provides a baseline of normal network behavior. The processor raises an alarm whenever the attribute information exceeds a predetermined range of deviation from the baseline of normal network behavior.
摘要翻译：用于计算机网络的入侵检测系统和方法包括处理器和在处理器上运行的一个或多个程序，用于对遍历计算机网络的数据分组进行应用检查。一个或多个程序还从特定于特定应用的分组中获取属性信息，并将属性信息与提供正常网络行为基准的知识数据库进行比较。每当属性信息超出与正常网络行为的基线偏离的预定范围时，处理器就会发出报警。

摘要： An intrusion detection system for a computer network includes a knowledge database that contains a baseline of normal host behavior, and a correlation engine that monitors network activity with reference to the knowledge database. The correlation engine accumulating information about anomalous events occurring on the network and then periodically correlating the anomalous events. The correlation engine generates a worm outbreak alarm when a certain number of hosts exhibit a role-reversal behavior. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
摘要翻译：用于计算机网络的入侵检测系统包括包含正常主机行为的基准的知识数据库，以及参考知识数据库来监视网络活动的相关引擎。相关引擎累积关于在网络上发生的异常事件的信息，然后周期性地关联异常事件。当一定数量的主机出现角色反转行为时，相关引擎会生成蠕虫爆发警报。要强调的是，该摘要被提供以符合要求抽象的规则，允许搜索者或其他读者快速确定技术公开内容的主题。提交它的理解是，它不会用于解释或限制权利要求的范围或含义。 37 CFR 1.72（b）。
