Embodiments described herein are directed to multiple hypothesis systems and methods for tracking observations that are domain agnostic and involves determining the probability that a given set of observations (i.e., a track) corresponds to a particular target, object or linked set of events. One embodiment described herein relates to cyber security tracking methods and systems.

Multiple hypothesis tracking

Described are computer-based methods and apparatuses, including computer program products, for signature matching. In some examples, the method for signature matching includes receiving a first target profile associated with a first data signal, the first data signal associated with a first target object; receiving a second target profile associated with a second data signal, the second data signal associated with the first target object or a second target object; generating a comparison distance utilizing a comparison distance function and based on a comparison of one or more data points associated with the first target profile and one or more data points associated with the second target profile; and determining a signature matching score based on the comparison distance.
