The presidential National Security Council (NSC) said Wednesday it has conducted cybersecurity drills to enhance integrated response between public and private entities against hybrid threats. The NSC organized the cyber defense drills in conjunction with the annual Ulchi civil defense exercise, involving military, government agencies, intelligence authorities and police, as well as private and public companies. The Ulchi civil defense exercise has been under way since Monday for a four-day run, held concurrently with the Ulchi Freedom Shield exercise jointly held between South Korea and the United States. The cyber defense drills focused on bolstering joint capabilities between public and public sectors to threats posed by hybrid warfare, which combines cyber threats and military provocations, the NSC said. The exercises took place at the National Information Resources Service in the central city of Daejeon and a major port in the southeastern city of Busan, simulating scenarios where key infrastructure facilities and the government network come under attack, it noted.
