The web could be divided into three layers – surface web, deep web, and dark web.
The Surface web is the part of the World Wide Web that all the general public could avail easily and searchable with standard web search engines. This is the internet we all know and love. This is the opposite of the deep web. It was first invented in 1990 by Tim Berner-Lee and you will be most familiar with it. It can be discovered through your internet browser using any of the main search engines(Google, Bing, Yahoo, etc.). This is also the area of the web that is under constant surveillance by governments across the world. Relatively it is small in size, only 5 percent surface web is available on the entire web. It is also known as “Visible Web” because that is being indexed by search engines.
The deep web is also part of the web whose contents are hidden behind HTTP forms and includes many common uses such as webmail, facebook, online banking and services, such as video on demand, and many more that users must pay for. The content of the deep web is not indexed by standard web search engines. Content of the deep web can be located and accessed by a direct URL or IP address and many require a password or other security access. All our important information like financial records, educational records, medical records, social media files are stored in the deep web for security purposes. Relatively it is bigger in size, approx 95 percent deep web is available on the entire web. Without proper credentials, we can’t access the deep web content.
The dark web is the part of the deep web that you can only access through so-called “overlay networks”.The dark web refers to encrypted online content that is not indexed by standard web search engines. The dark web is a component of the deep web that content does not appear through regular internet browsing activities. Its domain name ends with ‘onion’.Specific browsers like Tor are required to access dark web sites. The dark web attracts criminal actors like drug-dealers, hackers, child pornography peddlers, fake currency, illegal animal parts smuggling, etc. In this web, hides the user’s location and IP address so that it cannot be tracked. Dark web developed by US Military Research to allow spies and intelligence agencies to anonymously send or receive messages. But nowadays it is more widely used in illegal activities.
You stay away from the dark web because using it can put you in danger. And always remember to keep your personal credentials safe and your antivirus software up to date and use VPN (Virtual Private Network) to secure your browser and always be careful when following links that don’t look safe.
