DHS Orders Pipeline Operators to Report Cyberattacks, Review Security Posture On the heels of the Colonial Pipeline attack, the US Department of Homeland Security aims to force a reticent industry to improve its ability to detect and respond to cybersecurity attacks. The US government has issued a security directive that requires critical pipeline owners and operators to take significant steps to improve cybersecurity following the ransomware attacks on Colonial Pipeline earlier in the month. Today's security directive, issued by the US Department of Homeland Security's (DHS) Transportation Security Administration (TSA), requires critical pipeline operators, such as Colonial Pipeline, to report all confirmed and potential cyberattacks, improve their incident response by assigning a cybersecurity coordinator, and create a cybersecurity plan based on the results of a comprehensive threat assessment conducted within the next 30 days. The US pipeline infrastructure consists of more than 2.7 million miles of infrastructure for transporting fuel, chemicals, and other materials for use in businesses and homes.
