摘要
本文探讨了企业内部网常用的安全解决方案——防火墙技术——存在的若干安全隐患,指出了内部网络本身安全防范的重要性;通过介绍端口扫描技术、网络服务漏洞等细节,说明了内部网络受攻击的原理;最后设计并实现了一个漏洞安全检测系统(SD),它能有效地检测出大部分安全漏洞,并提出相应的解决方案,以实现内部网络的安全。
In this paper we discuss some security problems of firewall, which is often used as an absolute security solution to Intranet. By presenting several port scanning techniques and the concept of security holes,we describe the underlying principle how an Intranet is attacked. At last we design and implement a security detector system(SD) .which can detect most security holes and come up with corresponding solution.
