IDENTIFYING UNUSED PRIVILEGES IN A DATABASE SYSTEM

Techniques for identifying unused privileges are provided. Database accesses are monitored to generate privilege usage data. Privilege usage data for each database access may indicate a user, a utilized privilege, an object that is the target of the privilege, and a role to which the privilege is granted. The privilege usage data is compared to database authorization data that indicates all (or a subset) of granted privileges. A result of the comparison is unused privilege data that indicates what granted privileges were not utilized. A role graph may be generated that indicates one or more privileges that were utilized and one or more privileges that were not utilized along with role paths providing the privileges.
