    • A method of managing network usage by defining a set of linguistic patterns, where each linguistic pattern is associated with a condition that is to be monitored. Network packets are captured during transmission and analyzed to identify linguistic patterns. Captured network packets are scored based on similarity of at least one linguistic pattern to one or more of the defined set of linguistic patterns. When a packet that is scored above a specified threshold value is identified, at least one responsive action is implemented. In this manner, a system implementing the method is able to identify network traffic that is associated with prospective malicious activity and thereby provide an early warning before damage has occurred.
    • 一种通过定义一组语言模式来管理网络使用的方法,其中每个语言模式与待监视的条件相关联。 在传输过程中捕获网络数据包并进行分析,以识别语言模式。 基于至少一个语言模式与所定义的一组语言模式中的一个或多个的相似性来对获取的网络分组进行评分。 当识别到高于指定阈值的分组时,实现至少一个响应动作。 以这种方式,实现该方法的系统能够识别与预期恶意活动相关联的网络流量,从而在发生损害之前提供预警。

    • A system for monitoring and maintaining an acceptable use policy for network communications monitors, stores and searches for the presence of preselected regular expressions, either by subject category or by keywords. The regular expressions within the subject categories are assigned predetermined values, either negative or positive. If a communication contains regular expressions whose sum of weighted values exceeds a threshold value, the communication is stored for subsequent review by an authorized user of the system. If the communication contains keywords selected by the authorized user, the communication is also stored for subsequent review.
    • 用于监视和维护网络通信的可接受使用策略的系统通过主题类别或按关键字来监视,存储和搜索预选正则表达式的存在。 主题类别中的正则表达式被赋予预定值,无论是负数还是正数。 如果通信包含加权值的总和超过阈值的正则表达式,则该通信被存储以供系统的授权用户随后审查。 如果通信包含由授权用户选择的关键字,通信也被存储以供后续审查。
