Abstract: A method for automated computer security policy generation and anomaly detection includes receiving first network traffic data via an input port. The first network traffic data includes multiple data packets. A representation of each of the data packets is stored in a first data store, to produce a set of training data. A set of communication protocols associated with the set of training data is detected, and the training data from the set of training data is restructured based on the set of communication protocols, to produce processed data. The processed data is stored as non-malicious data in a second data store. The first network traffic data is transmitted, in unmodified form, via an output port. Second network traffic data including multiple data packets is subsequently received, via the input port, and compared to the non-malicious data to detect an anomaly in the second network traffic data.

Abstract: In one embodiment, a processor-implemented method for controlling network traffic to and/or from at least one industrial machine, including: (a) receiving, as input, (i) a stored policy object in language form defining at least one desired behavior and/or operational constraint for the at least one industrial machine, and (ii) a stored machine profile defining an association between the language of the stored policy object and at least one control signal or instruction for the at least one industrial machine; (b) detecting, in network traffic to and/or from the at least one industrial machine, a transaction; (c) applying the received policy object and machine profile to the detected transaction to determine whether a desired behavior exists and/or whether an operational constraint is satisfied; and (d) modifying network traffic to and/or from the at least one industrial machine based on the determination in step (c).

Abstract: In one embodiment, a processor-implemented method for monitoring network traffic between a first device executing a software application and a second device coupled to the first device. The method includes: (a) the processor analyzing application-level data contained within traffic originating from and/or received by the first device, the application-level data including data provided to and/or provided by the software application; (b) based on the results of the analysis in step (a), the processor creating one or more access rules; (c) the processor receiving a request from the second device to access the first device, the request including application-level data; and (d) the processor determining whether the request received in step (c) complies with one or more of the access rules.
