Cost Prioritized Evaluations of Indicators of Compromise

A method for evaluating indicators of compromise (IOCs) is performed at a device having one or more processors and memory. The method includes receiving respective specifications of a plurality of IOCs, wherein the respective specifications of each IOC of the plurality of IOCs includes a respective cost associated with evaluating the IOC. The method further includes dynamically determining an order for evaluating the plurality of IOCs based on the respective costs associated with the plurality of IOCs, and determining whether a threat is present based on results for evaluating one or more of the plurality of IOCs in accordance with the dynamically determined order, instead of an order by which the plurality of IOCs have been received at the device.
