The Nuclear Regulatory Commission is facing a mass exodus of cybersecurity experts in the years ahead, which could limit its ability to ensure the nation’s nuclear power plants are safe from digital attacks, an internal watchdog found. Jack Corrigan writes in Defense One that Nearly one-third of NRC’s cybersecurity inspectors will be eligible for retirement by the end of fiscal 2020, and agency officials worry they aren’t training enough people to take their place, according to the NRC Inspector General. With nuclear power stations becoming increasingly popular targets for online adversaries, the shortage of cyber expertise could leave the agency struggling to do its job, auditors said.
