What is Proxy Server & How Does It Works

A proxy server is a server whose function is to mediate between the source and the target. Whether or not this source and destination are generally interconnected.

There is no reason not to use a proxy server. It has several applications, some of which are:

  • It is used to connect to a proxy server for forensic procedures.
  • Some people use proxy servers to bypass the control
  • People use proxy servers to bypass firewalls
  • Some people use proxy servers to speed up downloads.

How Does a Proxy Server Works?

As we said at the beginning of the article, a proxy server acts as an intermediary. We know that every computer needs an IP to connect to the Internet.

Assume that this IP address is a postal code that is not known to anyone other than the postman and sender. The Internet uses IP addresses to determine which data is sent to which computer. When a user sends a request over the Internet, the request first goes to the proxy servers.

The proxy server performs the user’s request over the Internet, collects the response from the webserver, and sends the collected data to the user so that the user can view that page in their browser.

A proxy server can change the user’s IP address, so the Web server does not know where the user is. It can encrypt the data, so the information running in the transmission process cannot be read.

Types Of Proxy Server

Different types of proxy servers are:

Transparent Proxy

A proxy is a port that sends the user’s IP address to websites and presents the user to the webserver.

Anonymous Proxy

This type of proxy protects information about a user’s browsing history.

Distorting Proxy

This type of proxy does not make the user’s real IP address available.

High Anonymity Proxy

This proxy constantly provides different IP addresses to web servers so that no one can determine which traffic belongs to whom.

So far, we are familiar with different types of proxies. We have discovered that hackers can use proxy servers to mask their true identities and prevent forensic procedures from locating them.

Free Proxy Server List

Many hackers are blocked by firewalls for malicious attacks such as DDoS attacks or brute force attacks. It handles recurring requests to the server and cut off their access from the server for a limited or permanent period of time.

This is how they find solutions in using proxy servers. Proxy servers can send unlimited hacker requests to the target at high speed.

To do this, a list of proxy servers is used, which are usually located in a file with the .txt extension, and the associated program takes this txt file and uses the IP addresses and proxy ports in this file.

Advantages of Using a Proxy Server

  • Increase network security

Most network administrators use proxies to protect users from hackers. All users are connected to the Internet through a proxy and not every user has to connect directly to the Internet.

  • Control users

The network administrator may prevent users from using certain programs.

  • Increase the speed of the site

A proxy server with caching capabilities can increase the speed at which a website accesses information. So if a user wants to check the website, the proxy will check whether a copy of that website is temporarily saved.

If the copy is in the cache, it sends the copy to the user, which is very efficient at capturing the internet bandwidth.

  • User ID Protection and IP Encryption

As explained at the beginning of the article, using a proxy server can hide the IP address to keep the user anonymous while browsing the Internet.

  • Share the Internet Connection on the Local Network

In some homes with multiple computers, the Internet can be shared with other computers on that local network through a proxy server.

  • Access to restricted resources

Today, due to restrictions on certain applications such as Telegram and Facebook or certain websites, the proxy servers can be used to bypass these restrictions.

What Protocols are Used on a Proxy Server?

Proxy servers typically use TCP / IP or IPX / SPX protocols to communicate with clients. Therefore, to use a proxy, you must use one of these protocols on the network.

Proxy Risks

Free proxy servers are very dangerous and it is recommended not to use such proxy servers. The proxy server has access to the user’s primary IP address, and information about the user’s Internet requests is stored somewhere. You also need to confirm its encryption capabilities.

You should be very careful while choosing these proxy servers because the common risks can outweigh any of these benefits.

Risk-Free Proxy Server

Free proxy servers are very dangerous, even those funded by ads, so it is best not to use such proxy servers.

Glass History

It has access to your primary IP address, and information about your Internet requests may be stored somewhere. Therefore, make sure that the proxy servers store data and that there are policies in place to enforce the rules.

If your goal is to have privacy on a proxy server. You should be very careful about this because the proxy provider cannot do this without your knowledge.

No Encryption

Using a proxy server without encryption is like not using it at all. If “not encrypted” your requests will be sent as plain text. So anyone can access the information easily by entering their username and password. So you also need to make sure that encryption is possible.
