网络空间安全面临的挑战及应对策略

[摘要] 当前网络空间安全威胁包括：大规模分布式拒绝服务攻击，众多主机被境外结构控制，关键信息存储在非本国品牌服务器中，用户借助翻墙软件逃过监控等。提出了应对网络空间威胁的措施——自主可控与互联网应用创新，具体包括自主研发CPU和路由器等核心硬件以及操作系统和数据库等系统软件。认为下一代信息技术从内容的深度和广度挑战现存的网络空间，形成了新的安全威胁，这需要国家加快下一代网络的部署及研发。

[Abstract] The main security threats of network space include large scale distributed denial of service attack denial of service attacks; many hosts controlled by foreign institutions; key information stored in many foreign brand servers; and users with special software who can escape monitoring. The main measures to deal with space threats are self controlled and Internet application innovation, including
1) independent research and development of core hardware including CPU and router and 2) system software including operating systems and databases. The next generation of information technology from the depth and breadth of content challenges the existing network cyber, which forms a new security threat. This requires China to speed up the research and deployment of the next generation network.
