Abstract: A selected time interval of previously stored events generated by a number of computer network devices are replayed and cross-correlated according to rules. Meta-events are generated when the events satisfy conditions associated with one or more of the rules. The rules used during replay may differ from prior rules used at a time when the events occurred within a computer network that included the computer network devices. In this way, new rules can be tested against true event data streams to determine whether or not the rules should be used in a live environment (i.e., the efficacy of the rules can be tested an tor debugged against actual event data).

Abstract translation: 由多个计算机网络设备产生的先前存储的事件的选定时间间隔根据规则被重放和交叉相关。 当事件满足与一个或多个规则相关联的条件时，生成元事件。 在播放期间使用的规则可能与在计算机网络中包含计算机网络设备的事件发生时所使用的先前规则不同。 以这种方式，可以针对真实事件数据流来测试新规则，以确定在活动环境中是否应该使用规则（即，可以针对实际事件数据来调试规则的功效）。

Abstract: First stage meta-events are generated based on analyzing time attributes of base events received from a network component. Second stage meta-events are generated based on a number of the first stage meta-events that have a time attribute falling within a time period. An amount of time that has passed since a most-recent second stage meta-event was generated is determined, and if a threshold time period does not exceed the amount of time that has passed since the most-recent second stage meta-event was detected, a third stage meta-event is determined.

Abstract: A connected light node (CLN) induction light ballast module for powering an induction lamp includes a printed circuit board having components mounted thereon and an earth ground region electrically isolated from a PCB ground region. A heat sink is disposed on a lower layer of the printed circuit board and electrically connected to the earth ground region, wherein a parasitic capacitance occurs between the printed circuit board ground region and the heat sink. A capacitive shield sandwiched by a lower insulating pad and an upper insulating pad is electrically isolated from the heat sink supporting the shield. A damping network electrically connects the capacitive shield to the PCB ground region. Switch-mode power converters are mounted above the upper insulating pad and the shield. The damping network suppresses noise by a parasitic capacitance between the PCB ground region and the heat sink during high frequency power converter operation.

Abstract: A rules engine with support for time-based rules is disclosed. A method performed by the rules engine, comprises receiving security events generated by a number of network devices. The security events are aggregated. One or more time-based rules are provided to a RETE engine. The aggregated security events are provided to the RETE engine at specific times associated with the time-based rules. The security events are cross-correlated with the one or more time-based rules; and one or more first stage meta-events are reported.

Abstract: A selected time interval of previously stored security events generated by a number of computer network devices are replayed and cross-correlated according to rules defining security incidents. Meta-events are generated when the security events satisfy conditions associated with one or more of the rules. The rules used during replay may differ from prior rules used at a time when the security events occurred within a computer network that included the computer network devices. In this way, new rules can be tested against true security event data streams to determine whether or not the rules should be used in a live environment (i.e., the efficacy of the rules can be tested and/or debugged against actual security event data).
