RISK SCORING OF CLOUD PERMISSION ASSIGNMENTS USING SUPERVISED MACHINE LEARNING

Abstract: techniques for calculating risk scores of entity assignments are discussed herein. the system generates a probability matrix using a collaborative filtering technique such as singular value decomposition. the probability matrix is populated with probability values for each entity representing a probability that, based on the various relationships or associations of that entity with other entities, the entity has been granted an assignment. risk values are used to provide a weighting value to assignments, separating relatively higher risk assignments from relatively lower risk assignments. the system thereafter calculates a risk score for one or more of the entities using the information in the assignment matrix, the probability matrix, and the risk values. the system can flag or identity one or more entities whose risk scores do not meet various criteria.
