  • User access group discovery
    Patent number: 12580922
    Abstract: A method, computer program product, and computer system are provided for user access group discovery. The method includes: generating a matrix that depicts the respective resources of a set of resources accessed by each of a plurality of users; obtaining, for each user, a similarity measurement using the matrix, wherein the similarity measurement is based on a comparison of the resources accessed by the user to the resources accessed by the other users; generating, for each user, a feature vector for clustering the users into user access groups, wherein the feature vector represents the resources accessed by the user; applying the feature vectors and the similarity measurements to a centroid-based clustering algorithm to obtain the user access groups; and outputting the user access groups for application in a security environment.
    Type: Grant

  • Changes in source code
    Patent number: 11397574
    Abstract: Embodiments for describing an impact of a change in source code on a trace are presented. One embodiment comprises determining whether or not a change in source code between a first version and a second version of the source code affects a trace output of the source code. Responsive to determining that the change in the source code affects the trace output, metadata descriptive of the change in the source code is generated.
