By Terry Thompson May 11, 2021 The ransomware attack on Colonial Pipeline on May 7, 2021, exemplifies the huge challenges the U.S. faces in shoring up its cyber defenses. The private company, which controls a significant component of the U.S. energy infrastructure and supplies nearly half of the East Coast’s liquid fuels, was vulnerable to an all-too-common type of cyber attack. The FBI has attributed the attack to a Russian cybercrime gang. It would be difficult for the government to mandate better security at private companies, and the government is unable to provide that security for the private sector. Similarly, the SolarWinds hack, one of the most devastating cyber attacks in history, which came to light in December 2020, exposed vulnerabilities in global software supply chains that affect government and private sector computer systems. It was a major breach of national security that revealed gaps in U.S. cyber defenses.
