    • Methods, systems, and computer-readable media are disclosed for packet sanitization. A particular method intercepts a packet of a packet stream, where the packet stream is transmitted in accordance with a particular protocol. The packet is analyzed based on a specification associated with the particular protocol. Based on the analysis, a data value of a field of the packet is replaced with a sanitized data value to create a sanitized packet. The sanitized packet may be injected into the packet stream or may optionally be forwarded to a signature module that checks the sanitized packet for malicious content. When malicious content is found, the sanitized packet may be dropped, the sanitized packet may be logged, the sanitized packet may be redirected, or a notification regarding the sanitized packet may be sent to an administrator.
    • 公开了用于分组消毒的方法,系统和计算机可读介质。 特定方法拦截分组流的分组,其中根据特定协议传输分组流。 基于与特定协议相关联的规范分析分组。 基于分析,将数据包的字段的数据值替换为消毒数据值,以创建消毒数据包。 消毒的分组可以被注入到分组流中,或者可以可选地被转发到签名模块,该模块检查消毒的分组以获得恶意内容。 当发现恶意内容时,可能会丢弃已消毒的数据包,可能会记录消毒的数据包,可能会重新定向消毒的数据包,或者可以向管理员发送关于消毒数据包的通知。
