Those who use the Internet regularly will certainly not be that unfamiliar with the terms Proxy or Proxy Server. Do you really understand and understand the concept of proxy server? What types of proxy servers are worth noting? To answer these questions, follow the Viettel IDC to the end of the article below.
What is proxy server?
To put it simply, Proxy-server considered a more secure means of connection between users and the Internet. This is an intermediary server between the end user and the website they are visiting. Proxy servers provide different functionality, security and privacy depending on user needs or company policies. Proxy Server user groups mainly come from organizations that need to secure private information and are typically businesses.
If you use a proxy server, Internet traffic will pass through the server on its way to the address you requested. This request will then return to the same proxy server (there are also exceptions to this rule) and it will forward data received from the site to the user.
Modern proxy servers can do more work, as in addition to forwarding web requests, they also perform data security and improve network performance. Proxy servers will act as firewalls and web filters, providing shared network connections and cache data to speed up common requests from users. A good proxy server can protect users and the internal network from unwanted things from the Internet.
Learn how proxy server works
As everyone knows, every computer on the Internet must have a unique IP address, and this IP address is the same as your home address. Just as the post office needs to know your home address to deliver mail, the Internet also needs to know the IP address of a user’s computer in order to send data to the correct computer.
A proxy server is basically a computer on the Internet with its own IP address that your computer knows. When you send a web request, it first goes. The proxy server will then make the web request and collect the response from the web server and forward the website data for users to view the web pages in the browser.
When the forwards a user’s web request, it can change this data and still get the information according to the request. The proxy server can change the IP address so that the web server cannot know the exact location of the user, together with data encryption, it also helps to improve security in transit. And finally, Proxy Server can help block access to specific websites based on IP address.
4 popular types of today
Transparent proxy
A transparent proxy will let websites know it is a proxy server and still use the user’s IP address identifying the web request. Usually, companies, public libraries or educational facilities often use transparent proxies to filter content when users can easily set up client and server names.
Proxy Server
Anonymous proxy
Anonymity Proxy, also known as Anonym Proxy, will not transmit the user’s IP address to the website. It improves security, prevents identity theft and prevents the site from delivering targeted marketing content based on a user’s location.
Impersonation power of attorney
Unlike the anonymous proxy that Viettel IDC shared above, an impersonated proxy machine will perform the function of protecting the user’s IP address by sending the wrong IP address to the web server. Therefore, users can pop up from another location to access blocked content.
Very anonymous proxy
Highly anonymous proxies periodically change the IP address at which they appear on web servers, making tracking user traffic very difficult. Among the types of proxies, it is no exaggeration to say that highly anonymous proxies are considered the most secure and efficient way to access the web.
