Web Security

When considering Web-based security for a network, knowledge of the entire Internet and the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol stack is a must. This chapter looks at Web-based security and topics including server and browser security, exploits, Web technologies such as ActiveX, JavaScript, and CGI, and much more.

Web Server Lockdown

Web server(s) store all of the Hypertext Markup Language (HTML), Dynamic Hypertext Markup Language (DHTML), Application Service Provider (ASP), and eXtensible Markup Language (XML) documents, graphics, sounds, and other files that make up Web pages. In some cases, it may also contain other data that a business does not want to share over the Internet. For example, small businesses often have a single physical server that performs all server functions for the organization, including Web services. A dedicated Web server, however, can serve as apathway into the internal network unless security is properly configured. Thus, it is vital that Web servers be secure.
