    摘要： Systems, methods, and apparatus are provided for vulnerability signature based Network Intrusion Detection and/or Prevention which achieves high throughput comparable to that of the state-of-the-art regex-based systems while offering improved accuracy. A candidate selection algorithm efficiently matches thousands of vulnerability signatures simultaneously using a small amount of memory. A parsing transition state machine achieves fast protocol parsing. Certain examples provide a computer-implemented method for network intrusion detection. The method includes capturing a data message and invoking a protocol parser to parse the data message. The method also includes matching the parsed data message against a plurality of vulnerability signatures in parallel using a candidate selection algorithm and detecting an unwanted network intrusion based on an outcome of the matching.

    摘要： A process is provided for etching a mask layer and removal of residue from a structure having an area sheltered from directional etching. The structure has a shape that forms a silhouette area obstructed from being etched by anisotropic bombardment originating from a first direction, and a mask formed over the mask layer over the structure; A first etch process removes at least a part of the mask layer and retains at least a part of mask layer in the sheltered area. A second etch process removes at least a part of the mask layer in the sheltered area by hydrogen based microwave plasma etching.

    摘要： The subject specification comprises a cognitive relay communications management (CRCM) component associated with a primary communication system, wherein the CRCM component controls relaying at least a portion of transmitted communications from a secondary source device (SSD) transmitting data to a secondary destination device (SDD) associated with a secondary communication system, in accordance with a specified relay protocol, such as a buffered decode-and-forward protocol. The CRCM component identifies when the secondary relay station (SRS) is not transmitting on the relay-destination (R-D) link and the source-relay link is not blocked, and, in such instance, allows transmission of a packet from the SSD to the SRS. The SRS forwards the packet to the SDD when the CRCM component identifies when the R-D link is not blocked. The SRS and/or SSD remove the packet from their respective queues when an acknowledgement message(s) is received from the SDD and/or SRS, respectively.

    摘要翻译： 主题规范包括与主要通信系统相关联的认知中继通信管理（CRCM）组件，其中，CRCM组件控制将从至少一部分发送的通信传送到从第二源设备（SSD）传送数据到次要目标设备（SDD） ）与根据指定的中继协议（例如缓冲的解码和转发协议）与辅助通信系统相关联。 CRCM组件识别辅助中继站（SRS）何时不在中继目的地（RD）链路上发送，并且源中继链路不被阻塞，并且在这种情况下，允许将数据包从SSD传输到 SRS。 当CRCM组件标识何时R-D链路不被阻塞时，SRS将数据包转发到SDD。 当从SDD和/或SRS分别接收到确认消息时，SRS和/或SSD从它们各自的队列中移除分组。

    摘要： An example method is provided and includes monitoring activity within an endpoint, and identifying a source associated with a particular data segment received by the endpoint. The method also includes monitoring an antivirus mechanism within the endpoint. The antivirus mechanism is configured to identify the particular data segment as being associated with malware. The source associated with the particular data segment can be communicated to any suitable next destination.
