物理隔离网络的安全风险研究

物理隔离是某些重要网络或信息系统为保护自身免受攻击而采取的手段,然而网络攻击技术的发展已使得单纯的物理隔离不能保证内网信息的安全,如何保证物理隔离网络的信息安全是目前亟需解决的问题.对防火墙、入侵监测等已有网络防护技术的不足以及物理隔离网络的失泄密途径进行了分析,针对物理隔离网络的攻击手段进行研究,并通过一种摆渡攻击来验证物理隔离网络所面临的安全风险.

Research on security risk of physical isolate network

Some important networks or information systems take the physical isolation as the main measure to keep themselves from being attacked.But, with the development of networksattacking technology, safety of networks or information is not ensured completely by physical isolation.It is a big problem to protect information in the physical isolation networks from being gave away.It has important meanings to analyze the insufficiency of the present networks defense technology, fireworks and intrusion detection syste...
