With the continuous development of network attack techniques, the attack frequency is increasing continuously, which not only makes the server security suffer more threats, but also increase the system administrator’s work difficulty and intensity. This paper expounds the technical principles of the attack for servers, introduces the methods and measures for simplifying server’s maintenance and improving server’s security protection level by using the security protection tools.%由于网络攻击技术不断发展,攻击频率不断增多,不仅使服务器安全受到更多威胁,也加大了系统管理员的工作难度和强度。阐述了针对服务器攻击的技术原理,介绍了利用安全防护工具简化服务器维护工作和提高服务器安全防护等级的方法和措施。
