erver protects your privacy by being the ‘middleman’ between you and a real server. When you visit a website, it intercepts your requests to determine if it can manage your requests by itself. If it can’t take care of your request, the proxy server will send the request to the real server. Thus, it provides you with indirect access to real servers.

Since real servers can’t directly access your information (e.g. browser type, location, IP address, internet service provider), this information can be prevented from being discovered by the real server.

Proxy servers are used to avoid recognizing information from the requests of the user. These are called anonymous proxy servers. Nowadays, numerous anonymous proxy servers are already available on the Internet. You can find lots of free services.

With proxy servers, it is not only your IP address that is being protected. Making your computer and yourself more anonymous through the use of proxy servers is possible.

For instance, linking proxy servers can provide you and the real server with a higher degree of “separation”. This makes it more difficult for would-be attackers to track you down. Also, if you encrypt data right at the outset, you can have an advanced degree of protection.

Once data is received and before it is forwarded, a proxy server can effectively encrypt data. However, a proxy server that is receiving unencrypted data will make the data open to harm. Usually, free anonymous servers do not encrypt data. You may need to pay a little amount to avail this kind of service and this may be very well worth it for you.

If you want to utilize an anonymous proxy server, see to it that the one you will use is well known for the quality of its service (preferably with posted privacy policies).

It is very important to keep in mind that proxy servers can’t guard you from someone who can access the computer you are using (e.g. those who nose around you). In this case, you should ensure that you take the necessary steps to safeguard your data by clearing and deleting cache, search history, and cookies from your toolbars and browser.

A secure proxy is basically a middle man that receives requests intended for another computer and therefore acts on behalf of another. A proxy service is used often when a client computer on network is incompatible for a direct connection. One example would be the client being unable to meet security requirements of the server but may need to access certain services.

It may also be used for screening purposes to allow the administrator to control access to unwanted or undesirable sites. A proxy server may also be used for caching purposes which enables faster access to frequently used sites. All computers connected to a LAN access the Internet via single IP address which results in improved security simply because the number of ports exposed is less than they would have been otherwise.

Proxy servers work on the seventh layer of the OSI model; the application layer. It tends to be application dependant unlike firewalls that work differently on lower layers. They are not as easy to install either and are often more difficult than to maintain than firewalls because proxy functionality for each application is protocol like HTTP, SMTP or SOCKS must be configured one at a time.

However, a properly configured secure proxy server will improve security and performance. As proxy servers function at the OSI application layer, their filtering capabilities are relatively intelligent. For example, proxy web servers can check the URL address of outgoing requests for web pages by inspecting HTTP GET and POST messages.

By using this function, network administrators can bar access to certain sites but can allows access to others. Normal firewalls cannot see web domain names inside those messages. Likewise for incoming data, ordinary routers can filter by port number or network address, but proxy servers can also filter based on application content inside the messages. There are many popular proxy servers available for Windows.

WinProxy is widely used. One of the reasons for this is that no software has to be installed on the client computers. This means that it is more efficient and it can be setup alot quicker. This is possible because WinPorxy is a transparent proxy server meaning that it can also provide NAT. Because of this the client computer is practically unaware of the proxy servers existence. Apart from the usual caching and security features it also supports important protocols like HTTP, FTP, NNTP and lots of others.

A WinProxy server can be setup and configured by following the steps below.

1. Install the TCP/IP protocol on all computers that are connected to the network

2. Run the Installation wizard and follow it through. You will need your product key

3. The following screens require information about your Internet connection. Select the type of connection and name it

4. Now enter the username and password for your connection

5. Your external and internal IP address is then configured. It automatically assigns a unique address to each device connected on the LAN

6. You then should disconnect from the Internet if you are connected at this stage

7. In the final step, WinProxy works through all the steps and will confirm that all operations have been executed successfully

8. The secure proxy should now be fully functional to use
