Evaluation of Web Site Security Concerns
It's unfortunate, but there are lots of ways in which web site security can be circumvented. Security hazards exist which could impinge on Web servers and LANs (local area networks) on which Websites are situated, even by the typical use of a Web browser.
Web Masters bear the brunt when coping with the most dangerous challenges. As soon as a Web server is installed at a site, a porthole is made in the local area network through which anyone on the Internet can peer. Of course, for the most part web site visitors look at only what they're supposed to look at, but some try to unearth parts of the site that are not designed to be evident to the public. Nefarious visitors wish to do more than simply look; they endeavour to unlock the window and slip in. The damage intruders could inflict might be mere vandalism, for example changing the website's home page with one of theirs that might say or show anything at all, or else it might be theft, like appropriating a customers or sales list.
It's difficult to avoid the probability that complicated software includes bugs. Regardless of how carefully it is tested, there will be usually a certain order of events or user actions, even though it might appear once in a blue moon, which brings about a failure. Computer software bugs give rise to gaps in system security. A Web server is complicated software that can quite likely contain a security defect.
It is not only the complexity of a Web server which may create a problem, but also its open architecture. Consider a CGI script as a case in point. A CGI script may be processed at the server in response to a remote call from a client. It could be a request from a program or even the click of a button in a browser. If the CGI script has a bug, there is a possibility of a security violation.
Network Administrators also have to cope with problems from Web servers by reason of the risk they pose to the security of the local area network. Though there should be no unauthorised incursions, access must be granted to website visitors. This means that access to the network should be controlled. The Administrator therefore must perform a delicate balancing act. Even the most sturdy firewall can be undermined if the Web server is configured badly. Bearing that in mind, normal use of the web site may be not possible if the firewall is configured badly. Reaching an ideal resolution is even more tricky if an intranet is an element of the system. Normally, the Web server in that case must be configured to distinguish and validate domains and user groups, which are apt to have differing permission levels and access privileges.

Almost all people using a browser to surf the Net trust that they're doing so secretly and securely. This is not the case. Web browsers may run self-contained programs on the local computer which are hosted by a website. Modern browsers display a warning and ask permission to run those programs. Described generally as "active content", e.g., ActiveX controls or Java applets, these programs, if malicious, can easily leave a virus or other hazardous software on the browser user's computer. When it is in the system it can cause all kinds of damage and may be extremely tricky to delete.
This is also a worry for Network Administrators. Web browsers offer a way for possibly malicious software to filter all the way through the local area network's firewall. After it is in the network, the damage it could inflict can extend from secretly appropriating confidential information to wilful carnage.
Aside from the issues regarding active content, simply surfing the Net records a trail of the user's activities in the browser's history. This might be utilised by websites and installed software programs to establish an accurate profile of the user's behavior and preferences. Although this may be frowned upon as an invasion of privacy by some people, it can be beneficial by offering related content instantaneously, thus unburdening the user of the task of trying to find it.
Privacy is a matter that concerns not just browser users but also Web Masters and Network Administrators in the actual transmission of data via the Net. TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic language of communication for the Net. When it was created, security was not the most important aspect of its blueprint. Both network and Internet transmissions should therefore not be thought of as as essentially confidential. Each time the browser on a local PC downloads a confidential file from the remote Web server, or the browser user fills in a form with confidential data and clicks the 'Submit' button, the transmitted data can be intercepted without consent.
