Abstract: Anomalous or unexpected system permissions in applications in a computing environment are identified by generating a statistical model at least in part from application permissions granted across a plurality of application types. One or more of the application permissions granted across a plurality of application types are identified as potentially unexpected dangerous permissions. The statistical model is used to determine whether a target application has at least one potentially dangerous permission that is not statistically likely for a target application type of the target application.
