隐蔽式网络攻击综述

近年来,随着信息化的推进,国民经济各行各业对网络的依赖性明显增强,网络信息安全问题成为关系国家和社会安全的突出问题。受经济利益驱动,加上各国之间的博弈在网络空间的体现不断加强,具有高技术性、高隐蔽性和长期持续性的网络攻击成为当前网络安全面临的主要挑战之一。文章对这种隐蔽式网络攻击进行了介绍和描述,分析其主要特点和对当前安全体系的挑战。在此基础上综述了国内外隐蔽式网络攻击检测等方面的最新研究进展。最后,对关键技术问题进行了总结,并展望了本领域未来的研究方向。

A Survey on Evasive Network Attack

In recent years, due to advances in informatization, the national economy has become more dependent on networks. As a result, the network and information security has become a prominent problem for the national security and social stability. Driven by economic interests and the game between countries reflected in the growing cyberspace confrontations, network attacks with high-tech, high concealment and long-term sustainability become one of the major challenges in the network security. In this paper, the certain kind of covert attack was referred as the evasive network attack (ENA). Firstly, the main characteristics of ENA and the challenges it brings in current security systems were analyzed, based on which the latest developments at home and abroad for ENA detection and other related studies were reviewed then. Finally, key technical issues and future research directions in this field were summarized.
