Topwalk-UIS

Topwalk Secure One-Way Import System (Topwalk-UIS) is a network security product integrating security and efficiency, realizing physical one-way transmission of data across security domains. Composed of a Pre-Import Agent (PAS) and an Import Application Server (IAS), the product is deployed on both sides of a one-way isolation optical gateway. It provides a transmission channel for various data imports from low-security domain networks to high-security domain networks, suitable for government agencies, military units and large enterprises and institutions.

Core Values

Protocols supported

Support a broad range of leading domestic and international databases.

Support multiple file transfer protocols and services.

Support common MQ(message queue) protocols

Cross-Platform Adaptability

Ensures seamless client-side deployment across both Windows and Linux operating systems (all major versions), while enforcing one-way file transfer to maintain data integrity.

Log Audit

The system provides comprehensive auditing for transmission logs, system logs, and operational logs, enabling efficient incident localization and root cause tracing. It also supports log rollback, log backup, and log export to external systems.

Security Safeguards

The file exchange module and database import module are equipped with real-time virus protection. Meanwhile, the business module supports multi-dimensional data validation, including content filtering and format validation, to further strengthen the security of data exchange.

Security Authentication

The system supports a variety of authentication methods, including the registration and authentication of device certificates, IP, MAC, and other information for network terminals and servers. It rejects access requests from unregistered devices and supports multi-factor authentication, providing robust security for system usage.

One-Way Transmission of Service Data

The system provides robust data ingestion capabilities, enabling secure one-way transmission of highly sensitive data that demands the highest level of protection.

Product Advantages

Versatile Business Scenarios

The system supports various transmission methods, including file transfer, database synchronization, message queuing, and request services, catering to the transmission requirements of diverse application scenarios across different industries.

Strict Compliance with Secruity Requirements

The secure unidirectional import system is designed and developed in accordance with the requirements for unidirectional import devices specified in the "Security Specifications for Public Security Information Communication Network Boundary Access Platforms — Public Network Information Collection Part," meeting the isolation and exchange requirements outlined in the specifications.

Secure Recovery Mechanism

The system offers flexible backup and restoration functions. It supports not only manual backup of system and business configurations but also automatic and off-site backups. In the event of a sudden attack on the system server, it enables timely restoration of system configurations to ensure normal system operation.

Lossless Data Transmission

The system employs Forward Error Correction (FEC) technology to perform digest comparison on transmitted data streams, enabling timely detection of data loss and allowing manual retransmission. This significantly reduces the risk of data loss and ensures data integrity.

High Performance & High Stability Guarantee

To better adapt to data transmission in high-performance and high-stability scenarios, the platform employs advanced technologies such as zero-copy memory technology, huge page memory technology, and token bucket-based traffic shaping technology. These innovations form a groundbreaking technical architecture that significantly enhances the system's data transmission capability and reliability.

Application Scenarios

The Topwalk Security One-Way Import System is purpose-built to enable secure, one-way transmission of files, database data, message queues, and service requests from low-trust network domains to high-trust network domains. It is ideally suited for government agencies, military units, and large-scale enterprises operating in high-security environments.
