Developing least-privilege permission sets based on global optimization

Abstract:

Disclosed embodiments relate to iteratively developing least-privilege profiles for network entities. Operations may include accessing a set of permissions associated with a network entity; obtaining a set of permission vectors for the network entity; evaluating each permission within the set of permission vectors, the evaluation being based on at least: whether each permission within the set of permission vectors provides sufficient authorization privileges for the network entity to perform an action, and a number of permissions in the set of permission vectors; selecting a group of the set of permission vectors; creating a new set of permission vectors for the network entity; iterating the evaluation for the new set of permission vectors; determining, following at least one instance of the iteration, whether an iteration termination condition has been met; and terminating the iteration based on the iteration termination condition being met.
