Caching proxy server, web proxy, content filtering web proxy and anonymizing proxy server are some of the kinds of proxies that are commonly accessed by computer users. Aside from these servers, the other types include the hostile proxy, intercepting proxy server, transparent and non-transparent proxy server, forced proxy, suffix proxy, open proxy server, reverse proxy server and tunneling proxy server. Furthermore, some work places and schools use a specialized kind of proxies known as a content filter, in order to avoid unauthorized requests and access to the Internet and other networks that usually store private and confidential data.
Proxy sites are web pages that allow computer users to browse the Internet without using the services offered by their Internet provider. They allow people to access web resources without revealing the Internet Protocol address of a computer system that they use. They also enable users to bypass content filters like WebSense and SmartFilter. To avoid having problems related to the use of these sites, it is important to prevent accessing the same site for several times. In addition, it is necessary to visit web pages that regularly update their proxy lists. Moreover, users should know the particular regions where such proxies can only be accessed.
Computer users should be aware of the problems that they may encounter when they use proxies. One of the risks that clients must know is the possibility that a malicious server may store every data or information that they will send using these applications. In order to avoid such risk, it is important if they use servers or web pages that implement a clear privacy regulation. In addition, it is advantageous if they will use proxies that were developed or created by people they know. Finally, clients must avoid passing confidential or private data using these systems to prevent experiencing privacy problems.
