Lots of people are using the Internet mainly for communication, interaction, and to reach services and information offered by a vast range of providers. But we can never remove the fact that in some establishments such as schools and offices, Internet connection is restricted and you are not allowed to access prohibited websites, which are not useful for schools and businesses.
That is why the development of anonymous proxy or web proxy servers are implemented to serve these needs. Also, you can search the Internet without revealing your IP address.
Anonymous proxy works by serving web pages requested by web surfers. The client computer is not directly connected to the webserver serving the web pages. The proxy is the one responsible for retrieving and sending information from remote servers to client computers. It is like the proxy is the middleman between a remote server and the client.
One main purpose of anonymous proxy is to protect the privacy of an individual by hiding his computers information such as IP address, MAC Address, etc.
Other proxies are used to bypass firewall restrictions, which are commonly implemented in schools, government offices and businesses requiring strict policies to better utilized their Internet connection for official use. If a company does not have an effective monitoring tool and firewall policies, office productivity will be lessen because office workers will only use proxy servers to access their favorite websites.
These situations also happen to various schools, which does not have a strict implemented policy.
That is why it is very important that IT security administrators make necessary adjustments to their security policy to track down these proxy websites and block them in their system.
But there is also the disadvantage of using anonymous proxy. So users should be aware of the circumstances. Because anonymous proxies are open to public, you may never know if your personal information such as username and password is secured.
Clients using anonymous proxy servers send their data unencrypted. Normal users who do not have technical knowledge on how information travels are currently the common victims of information theft. There are lots of anonymous proxies servers who are malicious enough to record and capture your username, password, and other personal information, which might be useful to them.
So it is better to analyze first each proxy server you are using before browsing any website and supplying your password using their service. You may never know that you are accessing financial website which is not the genuine one.
