    Abstract: A system includes network nodes, such as, multiple computing devices and multiple software defined radios. The network nodes accurately and timely detects, identifies, locates, and responds to an unmanned aircraft system within a predetermined area. The network nodes use a communications control link between the unmanned aircraft system and a controller of the unmanned aircraft system to detect, identify, locate, and respond to the unmanned aircraft system. The network nodes are deployed over the predetermined area to maintain airspace situational awareness of the unmanned aircraft system, and deploy targeted countermeasures to counteract identified threats associated with the presence of the unmanned aircraft system within the predetermined area.

    Abstract: An illustrative system may comprise a plurality of distributed network nodes hosting a two-dimensional distributed digital ledger. The distributed digital ledger may have a plurality of chains of digital blocks in the two-dimensions, wherein each chain may be associated with a particular functionality (e.g., a first set of integrated circuit processes) and a corresponding level of security. For example, a first chain in the first direction may contain digital blocks containing code differentials of the hardware description language code forming the integrated circuit design. A second chain in a second direction may contain digital blocks containing simulation data records generated during the simulation of the integrated circuit design. The first chain and the second chain may be based upon different cryptographic protocols and therefore may be cryptographically separate from each other.

    Abstract: In general, this disclosure describes media stream transmission techniques for a computing device. The computing device captures a first media item and identifies a primary portion of the first media item and a secondary portion of the first media item different than the primary portion. The computing device applies a first compression algorithm to the primary portion of the first media item to generate a compressed primary portion. The computing device applies a second compression algorithm to the secondary portion of the first media item to generate a compressed secondary portion, where a data compression ratio of the second compression algorithm is greater than a data compression ratio of the first compression algorithm. The computing device transmits, to a central computing device, the compressed primary portion of the first media item and the compressed secondary portion of the first media item.

    Abstract: A runway capacity forecast system includes machine instructions stored in a non-transitory computer readable storage medium, the machine instructions, when executed, causing a processor to access data items related to a runway of interest for a time horizon of interest, the data items comprising environment factors for the runway of interest and the time horizon of interest, flight operation factors, and aircraft performance factors for aircraft scheduled on the runway of interest and during the time horizon of interest; extract data elements from the data items; reformat the data elements as analyzable data elements and store the analyzable data elements in an analyzable data structure; apply a probabilistic model to selected ones of the analyzable data elements to provide a forecast runway capacity for the runway of interest during the time horizon of interest the first product; and using the forecast runway capacity, determine one or more impacts based on the forecast capacity.

    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: An integrated adaptive learning system provides the functions of scenario development, exercise execution, exercise monitoring, exercise evaluation, exercise adaptation, and scenario feedback, which may be implemented in one or more of a scenario builder module, an exercise test module, an exercise controller module, an exercise performance monitor module, an exercise evaluation module, an exercise adaption module, and an exercise reporting and scenario feedback module. The modules, and other components of the integrated adaptive learning system may be implemented as a standalone physical training system, a training overlay to an existing physical system, and a virtual training system, or combinations thereof. In an aspect, the integrated adaptive learning system may be implemented as a physical or a virtual variable-fidelity cyber range.

    Abstract: Embodiments for a method of implementing multiple domains in a network switching device are disclosed. The method includes assigning a plurality of hardware ports to a plurality of domains. Ports are assigned to at least two of the plurality of domains, and none of the ports are concurrently assigned to multiple domains. The method also includes loading rules for forwarding packets between the plurality of ports into a data plane. The rules direct the data plane to forward only between ports in a common domain of the plurality of domains. The method also includes assuring that a packet received at any port assigned to a first domain is not sent in legible form from any port assigned to a second domain if an error causes the data plane to forward or request forwarding the packet to any port assigned to a second domain.

    Abstract: Disclosed herein are embodiments of systems, methods, and products comprise an analytic server, which provides a SilverlineRT system that prioritizes and analyzes security alerts and events. The server builds an attack tree based on attack detection rules. The server monitors large-scale distributed systems and receives alerts from various devices. The server determines attacks using the attack tree while excluding false alarms. The server determines impact and risk metrics for attacks in real-time, and calculates an impact score for each attack. The server ranks and prioritizes the attacks based on the impact scores. The server also generates real-time reports. By consider the mission and system specific context in the analysis alert information, the server gives insight into the overall context of problems and potential solutions, improving decision-making. By showing the impacts of alters, the server allows security personnel to prioritize responses and focus on highest value defense activities.

    Abstract: A computer-implemented method for managing enterprise transactions includes creating an overlay to a physical communications network, adding one or more nodes to the overlay, designating one or more nodes of the overlay as super nodes, generating a distributed ledger to store the transactions, and replicating the distributed ledger to all nodes of the overlay. Generating the distributed ledger includes receiving, at the super nodes, transactions from the one or more nodes, assigning, by the super nodes, the transactions to a variable size block, validating, by the super nodes, the variable size block, and linking the validated variable size block to the distributed ledger.
