【摘要】 互联网技术的快速发展,促进了其在金融证券、电子商务、智能旅游、在线教育等领域的普及和应用,已经积累了海量的数据资源,提高了人们工作、生活和学习的便捷性。大数据、互联网、云计算在给人们带来便利的同时,也带来了安全隐患。网络安全攻击、病毒和木马的增多,安全攻击已经呈现出智能化等特点,潜伏的周期更长,危害的范围更加广泛,给人们带来的损失更加严重。本文详细地分析了网络安全威胁现状,归纳了网络安全威胁攻击的特点和当前网络安全防御系统存在的问题,提出开发一个网络安全主动防御系统,并且采用多层次、纵深性主动防御策略,提高网络安全防御性能,保证网络的正常运行。更多还原

【Abstract】 The rapid development of internet technology promotes its popularization and application in the field of finance and securities,e- commerce,intelligent tourism and online education,which has accumulated vast amounts of data resources,improve people’s work,life and the convenience of learning. Big data,the internet,cloud computing bring convenience to people at the same time,it also brings security risks. The increase of network security attacks,viruses and Trojan technology development,channels for security attack have shown a intelligent characteristic,the latent period is longer,the harm’s scope is more extensive. It gave rise to the loss of more serious. The paper makes detailed analysis to the present situation of threat of network security development and sums up the characteristics of network security threats and the existing problems on current network security defense system. It puts forward to develop a network installation of active defense system and the use of multi- level,the depth of the active defense strategy,in order to improve the performance of network security defense and ensure the network normal operation.更多还原
