初步探究网络攻防技术设计方案书组员:XXX,XXX,XXX摘要随着计算机互联网技术的飞速进展，网络安全已经成为其重要组成部分之一，也是当今信息化时代的一个重要话题。针对硬件系统、网络协议及数据库等，不论是其本身的设计缺陷，还是人为的因素而产生的各种安全漏洞，都有可能被一些另有所图的黑客利用而发起一系列的攻击，因此建立一个有效的网络安全防范体系迫在眉睫。本文分析了网络攻击的一些步骤、方法及常用攻击工具等，并着重从这些方面来详细的介绍一些网络攻击与防备的方法，让读者了解黑客攻击的过程，在对待网络威胁时做好充足的准备，从而确保网络运行的安全和可靠。 关键词： 网络安全 网络攻防 加密技术 钓鱼网站 DNS 欺骗 cookies 攻击 SQL 注入式攻击 端口漏洞扫描AbstractWith the development of the Computer Internet technology, Network Security not only has become one of the important part of it, but also is an important topic in today's information age. Aiming at the hardware system, network protocol and database and so on, whether the design of its defects, or numbers of Network security vulnerability caused by human factor, they may be some other graph used by the hacker and launched a series of attacks. So establishing an effective network security system is imminent. In this paper, an analysis of network attack steps, ways and normal attack tools and so on, and focusing on these aspects to introduce some methods of the network attack and defense, to let the readers understand the process of hacker attack, to adequate preparation to do a good job in dealing with network threats to ensure safe and reliable network operation.
