安全隔離網閘 Topwalk-GAP

安全隔離網閘(topwalk-gap)


產品概述
天行安全隔離網閘(topwalk-gap)是國內首款基于網絡隔離技術實現安全信息交換的產品,2000年率先通過公安部、國家保密局的安全檢測,基于“2+1”多主機架構,切斷不同網絡域之間tcp/ip通信,實現網絡隔離基礎上的實時信息交換。可廣泛應用于政府、軍隊和大型企業等單位。


產品原理
天行安全隔離網閘采用多主機結構設計和專用硬件,切斷不同網絡域的tcp/ip協議通信,形成網間隔離。設備不接受任何未知來源的主動請求;數據讀取和發送通過主動請求和專用api接口的方式進行。通過自定義內容檢查機制為白名單策略提供進一步的保障。

核心功能
安全隔離
實現內外網之間的安全隔離,阻斷基于tcp/ip的網絡協議傳輸,安全隔離功能不受外部控制。
數據適配
提供文件、數據庫、消息和郵件等數據的適配功能,實現多種類型數據的采集和分發功能。
安全傳輸
針對不同類型數據,提供基于數據內容的深度檢測與過濾功能和數據傳輸方向控制功能,通過預定義安全傳輸策略,確保傳輸數據與用戶內網安全。

核心技術
安全隔離硬件是保障網絡間安全隔離的重要部件,它獨立于內外網單元,不接受外部的指令控制,實現數據在內外網單元間純數據擺渡;該部件由天行網安自主設計,擁有自主知識產權。安全隔離硬件通過獨立控制電路與讀寫保護電路保證信任網絡和非信任網絡之間鏈路層的斷開,從而保證網絡間的安全隔離。通過硬件實現安全隔離,徹底阻斷tcp/ip協議以及其他網絡協議,通過自定義的通訊機制進行數據的讀寫,實現可控的信息交換。
