Web Site Security Considerations - An Examination
It's unfortunate, but there are lots of ways in which web site security can be undermined. For example, security dangers exist which affect Web servers and LANs (local area networks) on which Websites are located, even by the normal use of a Web browser.
Web Masters are in the front line when managing the gravest challenges. As soon as a Web server is installed at a site, a porthole is fabricated in the local area network through which anyone who's on the Internet can look. Of course, for the most part website visitors look at no more than what they're supposed to look at, but a small number attempt to find areas of the site which aren't meant to be discernible by the world. Iniquitous visitors aspire to do more than just look; they try to open the window and slip in. The harm they can inflict might be mere vandalism, like replacing the web site's home page with one of their own that might say or display anything at all, or else it might be larceny, such as appropriating a contacts or orders database.
It is hard to elude the virtual certainty that intricate software includes bugs. Regardless of how painstakingly it's tested, there is usually some order of events or user actions, even if it may be infrequent, which leads to an error. Computer software bugs produce holes in system security. A Web server is involved software that may quite probably contain a security flaw.
It is not just the intricacy of a Web server which may cause a glitch, but also its open architecture. Think about a CGI script as an illustration. A CGI script may be run at the server in response to a remote request from a client. It might be a request from an application or even the click of a button in a browser. If the CGI script has a bug, there may be a possibility of a security violation.
Network Administrators also have to cope with problems from Web servers because of the risk they pose to the security of the local area network. Although there ought to be no unauthorized incursions, right of entry must be given to web site visitors. This means that access to the network should be controlled. The Administrator therefore has to perform a delicate balancing act. Even the most sturdy firewall can be breached if the Web server is configured poorly. By the same token, normal use of the website can be unachievable if the firewall is configured poorly. Reaching a model answer is still more difficult if an intranet is part of the system. Typically, the Web server then has to be configured to recognise and authenticate domains and user groups, which are likely to have varying permission levels and access rights.
Tip: For advice on a detailed facet of web site security, for instance "website security scanning", search for the full expression on the Net.
The majority of people using a browser to surf the Web trust that they're doing it namelessly and safely. This is not the case. Web browsers are able to process autonomous software on the client machine that are resident on a web site. Current browsers display a notice and request authorization to execute these kinds of programs. Known generally as "active content", e.g., ActiveX controls or Java applets, these programs, if malicious, could easily inject a virus or other hazardous software on the browser user's machine. After it's in the system it can wreak all kinds of havoc and may be extremely stubborn to eliminate.
This is also a worry for Network Administrators. Web browsers make available a route for potentially malicious software to filter through the local area network's firewall. As soon as it is in the network, the damage it can inflict can extend from clandestinely stealing confidential information to motiveless destruction.
Aside from the concerns regarding active content, just surfing the Web leaves a trail of the user's activities in the browser's history. This could be used by websites and installed programs to determine an accurate profile of the user's behaviour and preferences. While this might be frowned upon as an invasion of privacy by some, it can be constructive by offering appropriate content directly, thus relieving the user of the task of searching for it.
Privacy is a problem that worries not just browser users but also Web Masters and Network Administrators for the duration of the actual transmission of data by means of the Internet. TCP/IP (Transmission Control Protocol/Internet Protocol) is the fundamental language of communication for the Net. When it was formed, security was not the most influential factor of its blueprint. Both network and Internet transmissions should therefore not be considered as automatically confidential. Any time the browser on a local machine downloads a confidential document from the remote Web server, or the browser user fills in a form with private information and clicks the 'Submit' button, the transmitted data might be intercepted without consent.
