    • A method and system for providing virus detection. A virus detection system provides for the use of pattern matching techniques on data at a binary level for virus detection. Whenever an incoming data stream is received, the data stream is segmented into time-based data frames. The time-based data frames are processed to generate associated data frame images utilizing signal processing identification and filter techniques. One or more data frame images are compared to a stored virus image utilizing pattern analysis techniques. A pattern match value associated with each data frame image is generated based on the comparison and a determination is made as to whether or not the pattern match value exceeds a pattern match value threshold. When the pattern match value exceeds the pattern match value threshold, a pattern associated with the virus image is removed from the time-based frames to produce a filtered data stream.
    • 一种用于提供病毒检测的方法和系统。 病毒检测系统提供对二进制级别的数据使用模式匹配技术进行病毒检测。 每当接收到输入数据流时,数据流被分段成基于时间的数据帧。 处理基于时间的数据帧,以利用信号处理识别和滤波技术生成相关联的数据帧图像。 利用模式分析技术将一个或多个数据帧图像与存储的病毒图像进行比较。 基于比较生成与每个数据帧图像相关联的模式匹配值,并且确定模式匹配值是否超过模式匹配值阈值。 当模式匹配值超过模式匹配值阈值时,与基于时间的帧相关联的与病毒图像相关联的模式被产生过滤的数据流。

    • A system and method for enabling a network device to resume network activities in a secure manner on a communication network when network activities are generally blocked by protective security measures implemented by network security modules is presented. During its periodic update request, a network security module blocking the network activities of the network device requests updated security measures from an administrator-configurable security service. The security service determines whether the network security module/network device may receive a relaxed set of security measures that, when implemented by the network security module, enable the network device to resume some network activities. If the security service determines that the network security module/network device may receive a relaxed set of security measures, the relaxed set of security measures are returned to and implemented on the network security module, thereby enabling the network device to resume some network activities.
    • 提出了一种系统和方法,用于当网络活动通常被网络安全模块实施的保护性安全措施阻止时,使得网络设备能够以安全的方式在通信网络上恢复网络活动。 在其定期更新请求期间,阻止网络设备的网络活动的网络安全模块从管理员可配置的安全服务请求更新的安全措施。 安全服务确定网络安全模块/网络设备是否可以接收到一组轻松的安全措施,当网络安全模块实现时,网络设备能够恢复一些网络活动。 如果安全服务确定网络安全模块/网络设备可以接收到一组轻松的安全措施,则将一组安全措施放在网络安全模块上并实现,从而使网络设备恢复一些网络活动。
