Abstract: This disclosure is directed to techniques for providing communication between devices in different networks wherein the communication must first pass through an encryption mechanism and the devices do not have the stand-alone capability to encrypt or decrypt the communication. According to these techniques, an adapter may determine certain fields in a data packet that remain unencrypted when the data packet passes through the encryption mechanism. The adapter may then process those fields in such a way that, when the data packets are received by a second adapter, the second adapter may read those fields and obtain information.

Abstract: This disclosure is directed to techniques for communicating in an adaptive multicast network. In general, the disclosure is directed to communicating in an adaptive multicast network. This may be done by archiving, at a rendezvous point, multicast subscription information for terminal nodes in the adaptive multicast network, wherein the multicast subscription information comprises a dynamic list of receiver terminal nodes located within the adaptive multicast network that subscribe to particular multicast streams from one or more terminal nodes in the adaptive multicast network. A router receives a multicast stream from a sender terminal node. The router receives the multicast subscription information for the multicast stream sent by the sender terminal node from the rendezvous point. The router forwards the multicast stream to all receiver terminal nodes in the dynamic list of receiver terminal nodes indicated as subscribing to the multicast stream sent by the sender terminal node.

Abstract: A network defense system is described that provides network sensor infrastructure and a framework for managing and executing advanced cyber security algorithms specialized for detecting highly-distributed, stealth network attacks. In one example, a system includes a data collection and storage subsystem that provides a central repository to store network traffic data received from sensors positioned within geographically separate networks. Cyber defense algorithms analyze the network traffic data and detect centrally-controlled malware that is configured to perform distributed network attacks (“botnet attacks”) from devices within the geographically separate networks. A visualization and decision-making subsystem generates a user interface that presents an electronic map of geographic locations of source devices and target devices of the botnet attacks. The data collection and storage subsystem stores a manifest of parameters for the network traffic data to be analyzed by each of the cyber defense algorithms.

Abstract: This disclosure generally relates to automated execution and evaluation of computer network training exercises, such as in a virtual machine environment. An example environment includes a control and monitoring system, an attack system, and a target system. The control and monitoring system initiates a training scenario to cause the attack system to engage in an attack against the target system. The target system then performs an action in response to the attack. Monitor information associated with the attack against the target system is collected by continuously monitoring the training scenario. The attack system is then capable of sending dynamic response data to the target system, wherein the dynamic response data is generated according to the collected monitor information to adapt the training scenario to the action performed by the target system. The control and monitoring system then generates an automated evaluation based upon the collected monitor information.

Abstract: A modular green roof and/or green wall system includes a plurality of trays adapted to support vegetation and soil therein. The trays are sized such that a person may easily lift them and install them in a pre-vegetated state upon a roof or a wall. The trays are further designed to enable subterranean irrigation lines to be inserted therethrough, thereby hiding the irrigation lines from view. Biodegradable walls may be added of different heights to the trays to support different types of vegetation, as well as to create terracing for a given installation, if desired. A wicking material may be inserted into the tray and positioned such that is makes contact with wicking material in adjacent trays, thereby spreading moisture between trays through the capillary action of the wicking material.
