Abstract: Aspects of the subject disclosure may include, for example, systems and methods for identifying a first subscriber device that operates as a fiber connection extension control point, where the first subscriber device is connected to a fiber network via a wired connection, based on the identifying and a first subscription agreement, providing a predetermined fiber connection resource to the first subscriber device, identifying a group of neighbor subscriber devices located proximate to the first subscriber device within a predetermined threshold, slicing the predetermined fiber connection resource into multiple segments, and distributing, via the first subscriber device, the multiple segments to the identified group of neighbor subscriber devices. Other embodiments are disclosed.

Abstract: Machine learning techniques are provided for analyzing operational technology networks. An attack simulation model is trained to simulate attacks on a network replica by a plurality of threats. The attack simulation model outputs simulated attack data comprising a set of simulated attack paths corresponding to one or more threats of the plurality of threats. The network replica comprises a structured representation of a plurality of assets belonging to an OT network environment, communication pathways between the plurality of assets, security controls implemented in the OT network environment, and vulnerabilities. A threat analysis system is generated. The threat analysis system is configured to apply the attack simulation model to an input network replica and provide one or more risk reduction recommendations based on output simulated attack data from the attack simulation model. The threat analysis system is deployed to generate risk reduction recommendations for one or more OT network environments.

Abstract: Techniques are provided for operational technology (OT) network replication and attack path simulation. OT environment data describing a plurality of assets belonging to an OT network environment is received. A network replica of the OT network environment is generated based on the network data and the asset data. The network replica comprises a structured representation of the plurality of assets, communication pathways between the plurality of assets, security controls implemented in the OT network environment, and vulnerabilities. An attack simulation model is applied to the network replica and a threat database comprising threat data describing a plurality of threats. The attack simulation model simulates attacks by the plurality of threats on the network replica and generate simulated attack data describing a set of simulated attack paths corresponding to one or more threats. One or more risk reduction recommendations are provided based on the simulated attack data.

Abstract: Some embodiments of the time resilient system and methods disclosed herein can be configured to detect and defend against invalid time signals. According to various embodiments of the disclosed technology, the time resilient system include a receiver for collecting time signals sourced from an external clock. By way of example only, the external clock may be a high precision clock housed within a Global Positioning System. Other embodiments may include an internal clock calibrated to a time reflected on the external clock so that the internal clock and the external clock are synchronized. Additionally, a controller may monitor changes in time signals of the external over a period of time against the internal clock, where the system is alerted of a timing attack when the time signals collected from the receiver deviate a pre-determined time range with the time of the internal clock.

Abstract: The fire hose retrieval winch includes an elongated, rigid hose processing channel having a generally C-shaped cross section and open inlet and outlet ends, with the open side forming a lateral hose insertion and removal slot. An electrically powered drive roller draws the hose through the device, with a clamping roller bearing adjustably against the opposite side of the hose to provide tractive friction for the hose against the drive roller. The inlet end of the device may include opposed brushes for mechanically removing foreign matter from a hose passing therethrough, and opposed water nozzles for washing foreign matter from the hose. The hose retrieval winch is relatively small and portable and is installed removably in the existing trailer hitch of a vehicle to draw a deployed fire hose back to the vehicle for placement on the vehicle, with the device simultaneously cleaning the hose during the operation.
