TNC system and TNS system are two different systems, and they play different roles and functions in network communication.
TNC system (Trusted Network Connect System): The TNC system is a security framework for network access control. It provides a standardized method to verify and evaluate the security of network end devices and ensure that only end devices that meet specific requirements can access protected network resources. The TNC system mainly focuses on the health status, software integrity and configuration compliance of terminal devices to achieve network access control and security policy implementation.
TNS system (Transaction Network Services): TNS system is a system that provides global, safe and reliable payment and financial data communication services. It provides a platform for financial institutions, merchants and other financial transaction participants to connect and exchange payment transaction information. The TNS system involves network communications for payment and financial transactions, including transaction routing, data encryption, network connection management, etc., to ensure fast, secure and stable payment and financial data transmission.
In summary, the TNC system mainly focuses on network access control and terminal device security assessment, while the TNS system focuses on providing payment and financial data communication services. They have obvious differences in functions and application areas.
