An Examination of Web Site Security Issues



An unfortunate fact is that there are many ways in which web site security can be endangered. Security hazards exist which may have an effect on Web servers and LANs (local area networks) on which Web sites reside, even by the ordinary use of a Web browser.

Web Masters come under fire when managing the most dangerous risks. As soon as a Web server is set up at a site, a porthole materializes in the local area network through which anyone using the Internet can peek. Certainly, most website visitors see no more than what they're meant to look at, but a few endeavor to uncover elements of the site that aren't intended to be discernible by the rest of the world. Dishonest visitors would like to do other than simply look; they try to unlock the window and creep in. The damage they could cause might be mere vandalism, for instance replacing the web site's home page with theirs which might say or put on view anything, or else it could be larceny, like gaining possession of a customers or sales database.

It is difficult to elude the virtual certainty that complicated computer software has bugs. No matter how scrupulously it is tested, there exists typically a particular pattern of events or user actions, even if it may come about hardly ever, that creates an error. Computer software bugs produce flaws in system security. A Web server is complex software which can quite possibly contain a security opening.

It's not just the complexity of a Web server that can produce a glitch, but also its open architecture. Consider a CGI script as an illustration. A CGI script may be run at the server in reply to a remote request from a client. This could be a request from an application or even the click of a button in a browser. If the CGI script contains a bug, there could be a danger of a security violation.

Network Administrators also have to tackle problems from Web servers because of the danger they pose to the security of the local area network. Although there should be no unauthorized intrusions, right of entry has to be given to website visitors. This means that access to the network must be regulated. The Administrator therefore must perform a delicate balancing act. Even the most sturdy firewall may be breached if the Web server is configured poorly. Concomitant with this constraint, normal use of the web site can be unachievable if the firewall is configured badly. Attaining a perfect solution is even more difficult if an intranet exists as a constituent of the system. Typically, the Web server in that case needs to be configured to recognise and verify domains and user groups, which are apt to have varying permission levels and access privileges.

Tip: For ideas in relation to a specific facet of web site security, e.g. "online website security scan", search for the complete phrase on the Internet.

Almost everyone using a browser to surf the Net think that they are doing it in secret and safely. It is not so. Web browsers can execute self-contained software programs on the local machine which are hosted by a web site. Modern browsers display a notice and ask consent to run these kinds of programs. Well-known generally as "active content", e.g., ActiveX controls or Java applets, these programs, if malicious, may easily deposit a virus or other dangerous software on the browser user's computer. When it is in the system it can inflict all kinds of havoc and may be exceedingly tricky to delete.

This is also a worry for Network Administrators. Web browsers supply a route for potentially malicious software to seep all the way through the local area network's firewall. As soon as it is in the system, the damage it may cause can extend from secretly gaining possession of confidential data to wilful demolition.

Aside from the problems in re active content, simply surfing the Internet leaves a trail of the user's activities in the browser's history. This might be used by web sites and installed programs to create an exact report of the user's behavior and interests. Although this might be frowned upon as an invasion of privacy by some people, it can be beneficial by supplying appropriate content without delay, thus unburdening the user of the chore of looking for it.

Secrecy is a topic that worries not just browser users but also Web Masters and Network Administrators in the actual transmission of data via the Web. TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic language of communication for the Net. When it was formed, security wasn't the principal aspect of its design. Both network and Internet transmissions should therefore not be thought of as as automatically private. Whenever the browser on a local computer downloads a sensitive document from the remote Web server, or the browser user completes a form with confidential information and clicks the 'Submit' button, the transmitted data could be intercepted without consent.
