Abstract: Under one aspect, a computer-implemented method includes receiving a query at a query interface about whether a computer file comprises malicious code. It is determined, using at least one machine learning sub model corresponding to a type of the computer file, whether the computer file comprises malicious code. Data characterizing the determination are provided to the query interface. Generating the sub model includes receiving computer files at a collection interface. Multiple sub populations of the computer files are generated based on respective types of the computer files, and random training and testing sets are generated from each of the sub populations. At least one sub model for each random training set is generated.

Abstract: Described are techniques to enable computers to efficiently determine if they should run a program based on an immediate (i.e., real-time, etc.) analysis of the program. Such an approach leverages highly trained ensemble machine learning algorithms to create a real-time discernment on a combination of static and dynamic features collected from the program, the computer's current environment, and external factors. Related apparatus, systems, techniques and articles are also described.

Abstract: A system and method in one embodiment includes modules for identifying an asset with a vulnerability risk, identifying a service running on a port on the asset, identifying a connection to the port, calculating an operational dependence role of the asset as a function of the service and the connection, and modifying the vulnerability risk based on the operational dependence role. Other embodiments include identifying a protocol of a data packet at the port, classifying the protocol into a protocol category with a protocol importance score, calculating a connection average for the asset, classifying the connection average into a connection category with a connection score, and calculating a service dependence score. Other embodiments include calculating a host dependence score, assigning a data importance score to data communicated by the asset, and calculating the operational dependence role as a function of the host dependence score and data importance score.

Abstract: A sample of data is placed within a directed graph that comprises a plurality of hierarchical nodes that form a queue of work items for a particular worker class that are used to process the sample of data. Subsequently, work items are scheduled within the queue for each of a plurality of workers by traversing the nodes of the directed graph. The work items are then served to the workers according to the queue. Results can later be received from the workers for the work items (the nodes of the directed graph are traversed based on the received results). In addition, in some variations, the results can be classified so that one or models can be generated. Related systems, methods, and computer program products are also described.
