Many consider the internet to be one monolithic structure accessible via search engines like Google, Yahoo and Bing. In reality, quintillions of bytes are created on the internet each day, but this data is dispersed through 3 different parts of the internet - the surface web, deep web and dark web.Ī popular analogy for the anatomy of the internet is an iceberg - only a small percentage of it is visible when using a typical search engine. Whilst obtaining precise figures for the proportion of the internet attributable to either the surface, deep or dark web is difficult, most estimates place the proportion of the internet formed by the deep web at around 93%. It is likely to occupy less than 0.1% of the internet, with the remainder (around 6%) consisting of the surface web, which is indexed and accessible by standard search engines. There are various open source investigation (OSINT) techniques that investigators can use to understand deep and dark web activity, thereby allowing connections to be mapped across these three distinct components of the internet. Suggested reading: To learn more about best practices within OSINT investigations, check out our recent publication - The OSINT Handbook The Surface Web This article will break down the dark web, deep web and surface web, and look at the opportunities and limitations they have within OSINT investigations. The surface web is an information system formed by the world wide web and accessible to the general public via search engines.

It is crawled by bots, or spiders, which follow links (URLs) and analyse web content by reading code on the page. The web crawling process itself has two parts:crawling and indexing, the former referring to the process of crawling links to discover webpages, and the latter to the process of analysing the content on those web pages for indexing. The surface web refers to the indexed world wide web: the most popular information system used to access content over the internet.Indexed results will then appear on the search engine results page (SERPs).
