Adaptive anomaly detection for computer systems
Feature vectors are abstracted from data describing application processes. The feature vectors are grouped to define non-anomalous clusters of feature vectors corresponding to normal application behavior. Subsequent feature vectors are considered anomalous if they do not fall within one of the non-anomalous clusters; alerts are issued for anomalous feature vectors. In addition, the subsequent feature vectors may be used to regroup feature vectors to adapt to changes in what constitutes normal application behavior. |

Systems, methods and computer program products for ingress email security
An ingress server is operable to perform, through a multi-list evaluator, two different validations: one utilizes a sender network address of a sender's server to determine whether to trust, accept, or reject a connection and one utilizes a domain of a sender email address from an envelope to determine whether to accept or reject a message. The multi-list evaluator may perform the validations in two phases. If a connection can be trusted, the connection is accepted and any message over the connection (in a single session) is accepted and no further validation is necessary. Further, in both phases, the multi-list evaluator can utilize a whitelist maintained by the ingress server to override a blacklist provided by a blacklist supplier. This override can reduce false-positives and drastically reduce delays usually associated with correcting false-positives and improve system throughput. |

Using smart groups for computer-based security awareness training systems
This disclosure describes embodiments of an improvement to the static group solution because all the administrator needs to do is specify the criteria they care about. Unlike static groups, where the administrator needs to keep track of the status of individual users and move them between static groups as their status changes, smart groups allows for automatic identification of the relevant users at the moment that action needs to be taken. This feature automates user management for the purposes of enrollment in either phishing and training campaigns. Because the smart group membership is determined as the group is about to be used for something, the smart group membership is always accurate and never outdated. The query that determines the smart group membership gets run at the time when you are about to do a campaign or perform some other action that needs to know the membership of the smart group. |

Driving force control method and device for hybrid vehicle
Provided are a driving force control method and device for a hybrid vehicle, each capable of effectively absorbing torque fluctuation of an engine while suppressing deterioration in energy efficiency. The driving force control device for a hybrid vehicle comprises a PCM configured to: estimate an average torque output by an engine; estimate a torque fluctuation component of the torque output by the engine; set a countertorque for suppressing the estimated torque fluctuation component; and control an electric motor to output the set countertorque, wherein the PCM is operable, under a condition that an engine speed is constant, to set the countertorque such that, as the average torque output by an engine becomes larger, the absolute value of the countertorque becomes smaller. |

Direct current motor combinations for electric vehicles
A vehicular propulsion system is described that uses a plurality of direct current (DC) motors operatively attached to a common drive shaft or shafts of an electric vehicle (EV) or boat. Each motor is powered separately by direct current from a battery cassette or trays swappably inserted into the chassis of the vehicle. The battery cassettes are secured in racks, with one or more individual battery cassettes connected to each of individual motors. The individual battery cassettes are sized to have a weight suitable so as to be readily swapped out as needed for recharging, maintenance or replacement, enabling vehicle range to be extended en route by exchanging depleted battery cassettes for new batteries whenever needed. DC motors may be selected to obtain efficiencies greater than obtainable with AC motors, but require no expensive inverter unit. |
