Even the OSS’ Research and Analysis Branch in the UK, collected dozens of bunch of newspapers, to procure photos, articles, that would give them vital intelligence about the rival. 

In recent years many countries have taken the notice of OSINT. A powerful example of this came recently when a social media user posted a selfie that revealed the roof structure of the State Bomb Factory, which was destroyed by the US military in merely 23 hours. 

The market of Open Source intelligence has sprung up as you will find numerous OSINT firms have started to provide expertise to private and public sector clients in this field. 

3. Importance of OSINT. What is OSINT Utilized for?  

Information in the form of images, webinars, videos, speeches, and many others are also included in this list. 

When any crucial details of any corporation or individual are available without any restriction, then the intruder can easily make the SWOT analysis of such organizations or personalities and can comfortably penetrate the system by exploiting the vulnerabilities converting them into threats. The attackers can smoothly create a thread blueprint and plan accordingly. 

Attack over military security is a targeted cyber-attacks where the attackers acquire the information without the knowledge of the target that had begun with reconnaissance. 

Collection of OSINT on your own can assist you to a great extent to analyze the information open freely to the potential attackers without any financial efforts. The moment you get a hold over the type of information that can be accumulated from public sources, you can formulate the security policy to make the system more concrete against hackers and attackers.
