  • 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

  • Patent number: 11663324
    Abstract: Concepts for acquiring information for identifying a security configuration for an application are proposed. In particular, the information is obtained by running the application in a development environment, detecting security requests made on behalf of the application, and then storing security information associated with the security requests in a security log. Using this concept, a security log may be obtained from which an appropriate security configuration may be determined.
