Cybersecurity Information Exchange of Critical Infrastructures in the United States

Abstract

Cybersecurity information sharing for critical infrastructures has become a key challenge in modern cybersecurity governance. Timely information on cyber threats can help organizations strengthen their defenses, identify vulnerabilities and emerging threats, and mitigate the financial impact of cyber incidents. This study examines the current U.S. information-sharing framework and proposes measures to improve corporate participation as well as the quality and quantity of shared information. In this context, the paper outlines the potential reform of the ISAC system in line with the National Cybersecurity Strategy through the establishment of a mandatory critical infrastructure information-sharing model. The study seeks to identify the structural and regulatory factors that hinder the effective operation of the U.S. cybersecurity information-sharing system and to assess which reforms could improve its effectiveness. The research is based on document and literature analysis, with particular focus on the ISAC system and U.S. cybersecurity regulation. The findings suggest that the effectiveness of information sharing is primarily limited by low participation rates, lack of trust, interoperability challenges, and funding constraints, all of which undermine the cyber resilience of critical infrastructures if left unresolved.
