WASHINGTON (Reuters) - The Department of Defense's Office of the Inspector General released a year-long audit of a Navy commercial access control system on Tuesday that showed serious flaws because officials had tried to reduce costs.

As a result, 52 convicted felons received routine, unauthorized access to Navy facilities, the report said.

It said that unauthorized access had increased the security risk for military personnel, dependents, civilians and installations.
