1. A policy evaluation apparatus comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions to:
acquire a plurality of control policies for a respective plurality of control groups including an evaluation target group, each control policy indicating execution permission/non-permission of an application on a terminal included in a corresponding control group;
compare an evaluation unit that compares an evaluation target policy, which is the control policy for the evaluation target group, with a plurality of other control policies for a plurality of other control groups different than the evaluation target group; and
generate evaluation information based on a result of the comparison, the evaluation information indicating an entry of the evaluation target policy deviating more than a threshold from statistics of the plurality of other control policies.
