How to Setup a Proxy Server

In cyber networking, a proxy server is the one that sits between a client that requests a resource (your PC) and the server that provides it. It acts as a mediator between your browser and online services, such as SaaS providers. Proxy Servers can increase your online security and privacy and make your traffic go faster. 

Proxy Servers were designed to structure and concentrate distributed systems. So they function on behalf of the client upon service request, hiding the actual source of the request.

A Proxy Server functions in such a way that, instead of directly joining a server to fulfill a request, the client handles the request to the Proxy Server.  By assessing the request, the proxy server conducts the transactions. This method handles the complexity and length of the request and provides privacy and security.

Why set a proxy server?

A Proxy Server can observe users' internet use. You can use it to block sites with content you consider unacceptable. You can also program A Proxy Server to log all requests if you wish to find out what websites your employees go to while at work.

So a proxy server comes with certain benefits such as online anonymity and security, but its weaknesses are grave, and it's advisable to look for a safer solution.

Whenever you use a proxy server to go to a website, your device’s data is channeled through a third-party server, anonymizing your traffic. Proxy servers, however, have some security flaws, including:

1. Virus Attacks

Using a proxy server heightens the risk of virus attacks and spam. The moment you link to the proxy server, the server provider starts a session, storing your logs and showing banners and ads.

2. Security Hack

A proxy server directs your traffic via a third-party server. Whether you make transactions or simply surf the net, all your data goes through this server that some stranger owns.

3. Identity Theft

The main problem with a proxy server is logging your data and selling it to third parties. It increases the risk of data breaches.
