Can A Proxy Server Really Guarantee Me Privacy On The Internet?

May 6th, 2010 Comments off

So.

A proxy server grants you complete anonymity on the Internet.

Right?

I know a great many people who believe just that, thinking a proxy server affords some level of privacy.

There is, of course, some truth in that though it doesn’t describe the entire picture accurately.

To explain what I mean, we need to take a look at what a proxy server actually is.

A proxy server sits between your computer and the sites that you visit on the web.

It certainly prevents those sites from knowing who you are by masking your geographical location and IP address but that assumes that you have configured the proxy correctly in the first place.

The possible problem, though, is that you know absolutely nothing about the proxy itself –

Who owns it?
Are they collecting identifying data about you?
What are they doing with your data?
Is the person behind the proxy a hacker?
Or maybe an identity thief?

Chances are, you won’t know until its too late.

If you use a proxy then it can see everything you are doing, every request you make, unless it actively purges it’s logs on a regular basis.

Don’t forget that any user names or passwords you enter whilst using a proxy can also be captured and stored.

Worrying.

Isn’t it?

I guess the question you have to ask yourself is whether you trust the administrator of the proxy you are using?

Do you even know who they are?

Regardless of what they may or may not say about themselves on the site they could actually be anyone, from a teenage hacker to an identity thief or any other type of malcontent in-between.

Considering that the administrator of a proxy could be anyone, how secure do you feel now that you know that any browsing you do is in clear text?

Without any kind of encryption everything you do is available in clear text as the preferred protocol of the web – HTTP – was designed for speed and simplicity, not security.

The whole point of using a proxy is to make your surfing more private and more secure.

What you are really getting may be somewhat different though.

Do you think your privacy is being flushed away?

What is the Internet Proxy Server

May 4th, 2010 Comments off

The Internet proxy server is the server that is situated between the client application and an actual server. The Internet proxy server has the role of intercepting every request to the actual server and see if the request can be fulfilled by it. If that is not possible, then it must forward the request to the other server.

If used in an enterprise the Internet proxy server besides the role that it plays in all situations, also have the role of ensuring control and security. This Internet proxy server is linked to a gateway server. This has the role of separating the network of the enterprise from other networks. The Internet proxy server is also associated with a firewall server that is used to protect the network of the enterprise from any intrusions from the outside.

The Internet proxy server receives requests from web pages or any other Internet services from the user. Then if the filtering requirements are passed, the Internet proxy server checks its cache for other downloaded pages( this assuming that the Internet proxy server is a cache server as well ). If the web pages that are required are then found by the Internet proxy server, they are returned to the user. In this case there is no need for the Internet proxy server to forward the request. In case the page can not be found in the cache, then the Internet proxy server must act as a client as thus use its own IP address to request the web page from other servers that are found on the Internet. When the required page is then returned, the Internet proxy server reports it to the initial request and then it is forwarded to the user.

In the users eye, the Internet proxy server seems to be invisible. This is because the request and the response are so quick that the user is under the impression that they are made directly with the Internet server that was addressed. However, this is not the case and the Internet proxy server actually plays a very important part.

There are two main reasons why Internet proxy servers are used. One is to improve the performance and the second to filter the requests. The Internet proxy server can improve the performance for users, because the Internet proxy server actually saves all the requests that the user has made, thus making Internet operations a lot faster. The second reason why Internet proxy servers are used is to filter requests. This operation might be seen in schools or workplaces, where the employees are not allowed to visit certain web sites. This can be very easily done by configuring the Internet proxy server that is used.

Navigate Freely on the Internet by Using a Free Proxy Server

April 28th, 2010 Comments off

It is not acceptable that nowadays navigating on the internet is not made respecting the people’s privacy and that anyone who desires can find out the latest moves you made on the internet or can find out personal information like phone number, home address or even passwords and then use them against you.

Many people live in countries which do not allow certain believes and people can get executed just for visiting some web sites or just by writing a personal e-mail which contains complains regarding a government. Some countries even block some web pages in the attempt of “protecting “the citizens against the information those web sites contain.

For protecting our privacy when navigating on the internet, proxy servers have been invented. They are buffers between your computer and the Internet resources you are accessing. There are several types of proxies. There are the: HTTP proxy, the SOCKS proxy, the CGY proxy (the anonymizer), and the FTP proxy. Each type is designed to solve its specific tasks, however they have much in common, and their abilities coincide in many features.

Many people have found out that they can protect themselves and their computer by surfing anonymously. The anonymous surfing works by using an anonymous proxy server which will talk to the desired web site and then communicate the requested information to you. The free proxy sites are easy to use as they are only waiting for you to enter the address (URL) of the site you wish to go to and then they will retrieve the page for you and present it to you in a safe way. The other proxy sites which are not free need an additional program which has to be installed on your computer and they are more complicated.

The free proxy site will transmit to the web page only its IP address and will not sent you address too. In some cases if you use an anonymous proxy site you can be sure that not even the proxy site will know you IP address, so you are completely covered against any unscrupulous attack.

Besides hiding you IP address, free proxy servers can also hide the country and the region you are situated in and so no one can find you while navigating on the internet. Free proxy servers can also manage cookies. Cookies are dangerous as they can trace your activity on the internet and can give companies information about your net surfing.

You can find on the internet a lot of free proxy servers and you can choose one that you thing is best for you and your computer but you must make sure that this free proxy server is an anonymous one as it can protect your IP address 100%.
