Two cybersecurity researchers at Idaho National Laboratoryhave published a new book to help train employees at public utilities to recognize cybersecurity vulnerabilities and develop measures to defend their networks from increasingly sophisticated cyberattacks. , written by Andy Bochman and Sarah Freeman, details INL’s innovative approach to securing critical infrastructure systems like the electric power grid, oil and natural gas refineries and water treatment facilities.
