Due to the modern technology development, you are able to receive any desired info within seconds without making extensive efforts. All you need is to go online using any device with built-in transmitter, enter your request in web search engine and as the result thousands of pages appear on the screen. But sometimes your requests contradict to local privacy rules or web content security policy that makes websites inaccessible for one reason or another. In this case the user faces a problem known as internet censorship and which is synonymous to internet filtering.
What is the internet filtering?
The internet filtering is a technology which screens an incoming webpage to define whether some or all of its content should not be displayed to the user. The filter controls the origin and details of a page according to the rules instituted by political regime, organization or individual who has installed the filter.
As a result, the internet filtering mechanism allows blocking any content from the world web that can include undesirable advertising, pornographic and violent material, various types of malware and spyware etc. From this perspective, you can decide that this technology secures networks from cyberspace-based threats, but at the same time it violates freedom of access to the Internet.
The types of internet filtering
There are three common categories of internet filtering:
- Host-based when a system administrator establishes filtering software on the local net and connected devices. This type is usually utilized in the home and office networks.
- Server-side filtering is operated by larger institutions at the gateway level and controls incoming traffic providing more complete and strong protection.
- ISP-based content filtering enables to use third party services having tight control over the internet access.
On a basic level, internet filtering technology operates with a range of mechanisms (TCP/IP and HTTP protocols, proxy servers) pursuing one main reason to control web content and make it unavailable for users. The technology can be implemented in schools and homes protecting children from undesirable content or offices saving time of workers and restricting access to social media pages.
How to deceive internet filtering technology
There will be always those who do not agree with adopted rules and want to bypass internet filtering without breaking the law. The best choice is to use a VPN service which masks a real IP address and grants access to any web content you want. At the same time, it doubles net security encrypting all sending info and making it incomprehensible for a third party. With the best VPN you will enjoy secure and boundless internet space and forget about filtering.
