A multi-perspective user and entity behavior analytics (UEBA) system ('system') builds and maintains interchangeable modules for predicting likelihoods of anomalous user behavior at the scope of an actor (i.e., a user or entity) of an organization within time periods. Each module comprises probability models and/or machine learning models as sub-modules that model actor behavior at various levels of granularity with respect to usage of Software-as-a-Service applications. The system generates anomalousness scores by decorrelating likelihoods output by each sub-module and uses the anomalousness scores to monitor and perform corrective action based on anomalous actor behavior to maintain security posture across the organization.

Multi-perspective user and entity behavior analytics for software-as-a-service applications

The present application discloses a method, system, and computer system for classifying stream data at an edge device. The method includes obtaining a stream of a file at the edge device, processing a set of chunks associated with the stream of the file using a machine learning model, and classifying, at the edge device, the file before processing an entirety of the file.

Machine learning architecture for detecting malicious files using stream of data

The present application discloses a method, system, and computer system for classifying stream data at an edge device. The method includes obtaining a stream of a file at the edge device, aligning a predetermined amount of data in chunks associated with the stream of the file, processing a plurality of aligned chunks associated with the stream of the file using a machine learning model, and classifying, at the edge device, the file based at least in part on a classification of the plurality of aligned chunks.
