The first question asked during the incident response process, 

“What is going on?” is a critical question that requires information about past activity on systems and networks. An incident response process usually begins because someone observed an unusual symptom, such as network congestion, systems rebooting, or a defaced website. Incident responders normally turn first to records of recent activity, known as the audit trail, to explain the observed symptoms.

WHAT IS THE SURFACE WEB?

Everyone who has access to the internet uses the Surface web, or as some like to call it — the Clearnet. That content is indexed by different search engines like Google, Bing, Yandex, Duckduckgo, Yahoo, Baidu, etc. A typical search query consists of only keywords and even when you do not know the exact address of a website, those keywords are taken as inputs by the search engines to use their algorithms and give you the best results possible. Again — results consist of only indexed content by that search engine.
 
 
Although we use the Surface web for quite a long part of our days and feel like it is infinite, it actually is just a fraction of the whole package. The remaining part is hidden or invisible, but it is not impossible to access it.
