摘要： Detecting and mitigating threats to a computer network is important to the health of the network. Currently firewalls, intrusion detection systems, and intrusion prevention systems are used to detect and mitigate attacks. As the attackers get smarter and attack sophistication increases, it becomes difficult to detect attacks in real-time at the perimeter. Failure of perimeter defenses leaves networks with infected hosts. At least two of symptoms, roles, and reputations of hosts in (and even outside) a network are used to identify infected hosts. Virus or malware signatures are not required.
摘要翻译：检测和减轻对计算机网络的威胁对于网络的健康至关重要。目前防火墙，入侵检测系统和入侵防御系统用于检测和减轻攻击。随着攻击者越来越聪明，攻击越来越复杂，越来越难以实时检测到攻击。外围防御的失败会使受感染主机的网络丢失。网络中（甚至外部）的主机的症状，角色和声誉中至少有两个用于识别受感染的主机。不需要病毒或恶意软件签名。

摘要： A security system and service, which improves the performance of SECaaS services, is described. A security server system tracks the content that has successfully passed through its security modules and distributes this information to the end user client devices as hashlist information. The remote client devices can then safely bypass the cloud for a significant fraction of Web object requests by using information on a locally stored hashlist to validate Web objects.

摘要： File carving is a technique whereby data files are extracted from a digital device without the assistance of file tables or other disk meta-data, and can therefore be used to recover files that are fragmented. Sequential hypothesis testing procedures are used to detect a fragmentation point of a file by sequentially comparing adjacent pairs of blocks from the starting block of a file until the fragmentation point is reached. The detected fragmentation point can be used to help recover the fragmented file. Such a serial analysis helps to minimize errors and improve performance.

摘要： Several promising techniques have been recently proposed to bind an image or video to its source acquisition device. These techniques have been intensively studied to address performance issues, but the computational efficiency aspect has not been given due consideration. Considering very large databases, the efficiency of the sensor fingerprint based source device identification technique is described. Novel schemes that improve search complexity as compared to a conventional approach are described.
