Abstract

A system, method, and information processing system manage policy rules. A first unique identifier (121) associated with a first policy rule (120) is compared to at least a second unique identifier (130) associated with a second policy rule (202) in a set of policy rules (128). The first policy rule (120) and each policy rule in the set of policy rules (128) are associated with at least one common characteristic. The set of policy rules (128) are updated to include the policy rule (120) in response to the first unique identifier (121) failing to substantially match the at least second unique identifier (130). A notification (422) indicating a potential policy rule conflict exits between the policy rule (120) and the set of policy rules (128) is generated in response to the first unique identifier (121) substantially matching the at least second unique identifier (130).
