It can be used as an indication that optimization of the access policies is warranted. The access data can include access policies and / or access groups. A policy subgroup mapping process is performed to identify subgroups of access policies. Subgroups with a number of entries exceeding a predetermined value are converted to access groups, the users that have those policies are added to the corresponding access groups, and the individual access policies are deleted. Duplicative and / or redundant policies are identified and removed.
