The main purpose of the Data Infrastructure Risk Reduction Act is to enhance the security of data centers in the United States and to ensure the safety of the communities surrounding these facilities. The legislation aims to create a comprehensive strategy to protect data centers from external threats and to address any potential risks that these centers may pose to nearby residential areas. Key provisions of the Act require the Secretary of Homeland Security, through the Cybersecurity and Infrastructure Security Agency, to identify data centers that are deemed critical infrastructure.
