ＷＷＷ是Ｉｎｔｅｒｎｅｔ上的交流信息子系统，它促使了信息资源共享化，开发一个人类共有的虚拟知识库，也是信息研究开发者互相提供各种有用信息和交流思想的新途径。由于它采用了客户／服务器的软件体系结构，而 Ｗｅｂ服务器可接收来自Ｉｎｔｅｒｎｅｔ上未经坚定主机所发出的匿名申请，并迅速回应所需信息，此时恶意网络攻击者先攻击 Ｗｅｂ服务器，然后通过Ｔｅｌｎｅｔ、Ｒｌｏｇｉｎ、 ＲＳＨ、ＦＴＲ或 ＲＣＰ经该 Ｗｅｂ站点攻击网络其他端点，造成ＷＷＷ的安全威胁。 网络安全问题和ＷＷＷ的核心机制构成有很大关联。ＷＷＷ的核心机制由三大部分构成。 ＵＲＬ（ｕｎｉｖｅｒｓａｌ ｒｅｓｏｕｒｃｅ ｉｎｄｅｎｔｉｆｉｅｒ）统一资源定位法、ＨＴＴＰ协议（ｈｙｐｅｒｔｅｘｔ ｔｒａｎｓｆｅｒ ｐｒｏｔｏｃｏｌ）超文本传输协议、 ＨＴＭＬ（ｈｙｐｅｒｔｅｘｔ ｍａｒｋｕｐ ｌａｎｇｕａｇｅ）超文本标记语言，其中ＵＲＬ使用的协议可为ＨＴＴＰ超文本传输协议、ＦＴＰ文件传输、ＭＡＴＴＯ发电子邮件、ＴＥ ＬＮ ＥＴ远程登录、ＷＡＩＳ广域信息服务、ＮＥＷＳ新闻组等。
The WWW is an exchange information subsystem on the Internet. It promotes the sharing of information resources and develops a common human virtual knowledge base. It is also a new way for information developers and developers to provide each other with useful information and exchange ideas. Because it takes the client / server software architecture and the web server receives anonymous requests from unscheduled hosts on the Internet and quickly responds to the required information, the malicious cyberattack first attacks the web server and then passes Telnet, Rlogin, RSH, FTR, or RCP attacks other endpoints of the network via the Web site, causing a threat to the WWW. The issue of network security has a lot to do with the core mechanism of WWW. The WWW’s core mechanism consists of three parts. Universal resource indentifier, hypertext transfer protocol hypertext transfer protocol, hypertext markup language (HTML) hypertext markup language, where the protocol used by the URL may be HTTP hypertext transfer protocol, FTP file transfer , MATTO email, TE LN ET Telnet, WAIS Wide Area Information Service, NEWS newsgroups, etc.
