网络漏洞扫描技术

The Study of the Technique for Network Vulnerability Scanning

计算机网络安全是信息安全至关重要的一个环节 ,由于计算机网络系统的复杂性和网络技术的高速发展 ,无法保证网络系统是安全免疫的。网络漏洞扫描技术利用最新的网络安全技术以及时取得网络系统安全状况的最新信息 ,防止重大安全隐患的发生。同时协助网络管理者能够以最新的网络扫描技术及时有效地取得网络节点信息 ,分析网络系统的安全现状 ,以最大限度地保证网络服务的可靠性、持续性。

Computer Network Security is the most important part of the information security.Because of the complicated network and rapid development of computer network,no one can assure the non-existing of vulnerability.System administrator needs to receive the up-to-the-minute information with the new technology to avoid the hidden peril.With the development of Internet,the research on Network Security Technology has made rapid progress,among which network vulnerability scanning is the key ones.By studies on the development status of network vulnerability scanning,summering the scanning methods.Discussing detailly regarding the key technology,such as Host Discovery Techniques,Resource discovery Techniques,Probing objective service techniques,detecting remote host operation system type,etc..and also analyzing the current scanning technologies and its future development.The purpose is helping the system administrator with network vulnerability scanning to get the node information so as to ensure the continuity and reliability of network service.
