摘要
目前，网络攻击技术严重威胁着网络信息系统的安全，较为常见的攻击行为技术包括拒绝服务、恶意软件、利用脆弱性及内部攻击等。在设计网络防御系统时，不仅要考虑设计方案的目标与用户职责，同时还要重点进行网络风险分析，进而制定网络策略。可以说，通过网络、系统及数据三方面的各种安全技术手段，可以有效保护网络信息系统的安全性。
At present,network attacks,network technology, a serious threat to the security of information systems,the more common techniques include denial of service attacks,malicious software,the use of vulnerability and internal attacks.In the design of network defense systems,not only to consider the design goals and user roles,but also focus on risk analysis of the network,then the development of network strategies.It can be said,through the network,systems and data in three areas of security techniques,can effectively protect the network information system security.
