The U.S. Department of Energy Office of Inspector General has released a report on the July 28 security breach at the Y-12 National Security Complex, and it found “multiple system failures on several levels,” including ineptitude in responding to alarms, failures to maintain critical security equipment, misunderstanding of security protocols, and poor communications.
There was also an over-reliance on “compensatory measures,” and weaknesses in contract and resource management, said the 18-page report, released about one month after the security breach. In addition, “contractor governance and federal oversight failed to identify and correct early indicators of these multiple system breakdowns.
“When combined, these issues directly contributed to an atmosphere in which the trespassers could gain access to the protected security area directly adjacent to one of the nation’s most critically important and highly secured weapons-related facilities,” according to a summary of the report posted on the OIG website.
