Detection and mitigation of security threats to a domain name system for a communication network
The disclosure is directed towards the real-time detection and mitigation of security threats to a domain name system (DNS) for a communication network. A graph-theoretic method is applied to detect compromised DNS assets (e.g., DNS servers and web servers that DNS servers map domain names to). A graph is generated from domain name resolution (DNR) transactions. The nodes of the graph represent the DNS assets and edges between the nodes represent the DNR transactions. The graph is analyzed to detect features that signal compromised assets. The detection of such features serves to act as a binary classifier for the represented assets. The binary classifier acts to classify each node as non-compromised or compromised. The analysis is guided by supervised and/or unsupervised machine learning methods. Once the assets are classified, DNR transactions are analyzed in real-time. If the transaction involves a compromised asset, an intervention is performed that mitigates the threat. |

Energy storage power source using self-excitation of a wound-rotor induction machine (WRIM) to charge and discharge energy storage elements (ESEs)
A stored energy power source uses a wound-rotor induction machine (WRIM) to receive energy from a prime mover via a rotating shaft, provide magnetization reactive energy from a self-excited AC capacitor bank, store the energy in N energy storage elements (ESEs) via tertiary windings, and discharge the ESEs to deliver energy via a secondary winding to a load producing output. Each discharging ESE contributes to a total flux at the secondary winding to sum the individual ESEs voltages. These voltages can be stepped up or down by a transformation ratio between the secondary winding and each of the tertiary windings. A flywheel may be coupled to the shaft to store and delivery kinetic energy. Load factor power control can be used to stabilize the output voltage. The source may be configured to allow for the bi-directional flow of energy between the ESEs, the flywheel and the load. The WRIM provides a safe, reliable and efficient system to provide high-level AC and DC output voltages. |

Multivariate risk assessment via poisson shelves
Detecting fraudulent activity can be a complex, manual process. In this paper, we adapt statistical properties of count data in a novel algorithm to uncover records exhibiting high risk for fraud. Our method identifies shelves, partitioning data under the counts using a Student's t-distribution. We apply this methodology on a univariate dataset including cumulative results from phone calls to a customer service center. Additionally, we extend this technique to multivariate data, illustrating that the same method is applicable to both univariate and multivariate data. |
