Abstract: A method and system for determining a power consumption pattern for at least one application being executed on a computer is provided. The method comprises measuring a DC current and measuring a DC supply voltage provided to a data processing device, thereby creating a stream of time-stamped voltage value samples and current value samples. The method comprises further determining a product of the streams at identical times and converting the product into a real and an imaginary data stream using I/Q digital signal processing, combining these into a complex data stream, applying a signal processing demodulation step to the complex data stream, thereby generating a demodulated data stream, and extracting from the demodulated data stream at least one stream-based parameter signature, the at least one stream-based parameter signature representing the power consumption pattern of the at least one corresponding application being executed on the data processing device.

Abstract: A method for processing security events by applying a rule-based alarm scheme may be provided. The method includes generating a rule index of rules and an indicator of compromise index for each of the rules. The method includes also processing the incomingsecurity event by applying the rules, increasing a current rule counter relating to a triggered rule, and increasing a current indicator of compromise counter pertaining to the triggered rule. Furthermore, the method includes generating a pseudo security event from received data about known attacks and related indicators of compromise, processing the pseudo security events by sequentially applying the rules, increasing a current rule counter of pseudo security events, and increasing a current indicator of compromise counter for pseudo security events, and sorting the rules and sorting within each rule the indicator of compromise values in the indicator of compromise index.
