网络空间安全体系及关键技术

[摘要] 提出一种新型立体式网络空间安全体系结构，新结构有助于实现立体式网络空间安全防御体系，克服了传统线性防御体系只能应对单一性安全威胁的缺点。在新的体系结构中，网络空间中的节点分布于所有层次之中，且每一层的活动支撑着其他层的活动，并对整个网络空间产生影响。此外，针对所提出的立体式网络空间安全体系结构，结合当前的热点应用，指出了立体式网络空间安全防御体系应采取的关键技术。

[Abstract] A novel three-dimensional security architecture of cyberspace is proposed. This architecture has contributed to the construction of the three-dimensional security defensive system of cyberspace, and it overcomes the disadvantage of tackling only unitary security threats in the traditional linear defense system. In the proposed architecture, each node is involved in all layers in cyberspace, and the events in a layer affect other layers and thus affect the whole cyberspace. In addition, considering the proposed three-dimensional security architecture, security techniques suitable for the three-dimensional security defensive system are pointed out. These techniques are based on the current hot applications in practice.
