DHS will reportedly introduce the US's first cybersecurity regulations after the Colonial Pipeline hack revealed the fragility of American infrastructure

• The Department of Homeland Security will require pipeline companies to report cyberattacks.
• More mandatory rules will be announced soon - the agency has offered only voluntary guidance in the past.
• The Colonial Pipeline hack highlighted the country's need to safeguard its defense against cyberthreats.

US officials will introduce the country's first pipeline cybersecurity regulations after hackers attacked the country's largest oil pipeline earlier this month, causing a massive outage, The Washington Post reported Tuesday.

Unnamed officials at the Department of Homeland Security told the paper that the agency, through its Transportation Security Administration subsidiary, will issue a new directive this week requiring pipeline companies to report incidents of cyber vulnerabilities to officials. The new rules may also require companies to appoint a cyber official to have around-the-clock contact with federal authorities.

More regulations will be announced in the coming weeks for companies in an effort to ensure the safety of the industry's online infrastructure, the report said.

As the Post notes, DHS has historically issued only voluntary guidance on cyber safety, but these new rules will be mandatory. Other sectors involving things like health care and wastewater processes also don't typically implement required cyber guidelines.

DHS did not immediately respond to Insider's request for comment.

An agency spokesperson told the Post that "TSA, in close collaboration with [the Cybersecurity and Infrastructure Security Agency,] is coordinating with companies in the pipeline sector to ensure they are taking all necessary steps to increase their resilience to cyberthreats and secure their systems."

Colonial Pipeline, which operates the country's largest oil pipelines, was hit with a ransomware cyberattack in mid-May, and the company was forced to halt its operations temporarily. The 11-day shutdown resulted in supply issues in the southeast, as people took to panic-buying and hoarding gas. The hack also reignited conversations about how to safeguard the country's energy infrastructure.

Colonial's CEO said the company paid a $4.4 million ransom to foreign cyber hackers on May 7 so they would relinquish control of the systems. The FBI discourages companies from bowing to ransom requests, but many still do.
