Design and Research on the Secure Interconnection Access Standard of Port Inspection and Testing Equipment Based on Zero Trust Strategy

This study focuses on addressing Internet attacks caused by open network ports and application vulnerabilities, and specifically proposes access standards for port inspection and testing equipment based on a zero-trust strategy and integrating technologies such as PK and SPA. By integrating zero-trust single-packet authorization (SPA) technology into the access norms for inspection equipment and adopting soft certificates to address authentication challenges, the business services can achieve a state of “visible but inaccessible”, ensuring the secure interconnection of inspection and testing equipment and laying a solid security foundation for the digital transformation of ports.
