The Federal Protective Service, the agency that hires guards to protect federal buildings like courthouses and offices, would have to start testing those guards more rigorously—using undercover "covert tests" to see if they're actually doing their jobs—and require extra training for anyone who fails. The agency also has to check whether its computer system for tracking which guards are on duty and where gaps in coverage exist needs to be replaced or upgraded, and make sure people working in these federal buildings are promptly told if security coverage is missing. Congress would get regular progress reports on both efforts over the next several years, so the main people affected are the contracted security guards themselves and the federal employees and visitors who rely on that building security.
