United States of America: Issued TSA Cybersecurity Rules for Airports and Aircraft Operators

On 7 March 2023, the Transportation Security Administration (TSA) issued a new cybersecurity amendment on an emergency basis to the security programs of some TSA-regulated airport and aircraft operators as part of the US Department of Homeland Security’s campaign to improve the cybersecurity of US critical infrastructure.
