Topsec Security Isolation and Unidirectional Import System by Topsec Network Security is designed to ensure secure data transmission between networks of different security levels. It uses a '2+1' architecture that combines internal and external processing units with physical unidirectional transmission components to achieve secure information transfer. The system is based on a security-hardened operating system and consists of internal and external machines connected via physical unidirectional isolation components. It ensures absolute unidirectional physical transmission, preventing any reverse transmission channels and protecting high-security networks from data leaks. The system supports manual or automatic data transfer from low-security networks to high-security networks, ensuring compliance with national laws and regulations for data transmission. It includes multiple redundancy mechanisms to address packet loss during data transmission, ensuring data integrity and minimizing loss rates. The system also features built-in user permissions with independent storage areas for different classification levels, preventing unauthorized access to sensitive files.
