What is Open Source Intelligence?

OSINT stands for open source intelligence and it’s the process of gathering information about the target’s system, network and defenses without engaging it directly. In other instances, the target may be an individual or a group of individuals.
OSINT includes data from publicly available sources, such as DNS registrars, web searches, social media, security-centric search engines like Shodan and Censys.
Another type of open source intelligence is information about vulnerabilities and other security flaws, including sources like the Common Vulnerabilities and Exposures (CVE) and
Common Weakness Enumeration (CWE) resources
Examples of information that can be gathered during an OSINT engagement

  • Domain names and subdomains
  • IP Address ranges
  • Email addresses
  • Physical locations
  • Staff list and organization chart.
  • Documents’ meta data.
  • Social media information
  • Technologies and infrastructure.

Why will you need a notes system?

You could be actively working as an incident responder, security operations analyst, network security specialist or you could be preparing and studying for a certification exam such as Cisco Cyber Ops. In both cases, a set of notes maintained in your repository where you can search for commands, concepts or use cases that could aid you in the task you are performing is necessary for a productive studying and/or working.

What about the notes updates?

if you have been following my YouTube Channel, you definitely know that those who subscribe to the second tier of my channel membership they instantly get access to a vast catalog of cybersecurity, penetration testing, digital marketing, system administration and data analytics notes catalog for 10$ along with the ability to receive all notes updates as long as they are subscribed so what does that mean?

This means if you want to stay up to date with the changes and updates to the notes and get access to other categories, I encourage to join the channel membership second tier instead. However, if you are fine with downloading the current version of this section of the notes then you can buy this booklet instead for a one-time payment.

Will the prices of this booklet change in the future?

Once another version of this E-book is released, which it will, the price will slightly change as the booklet will include more contents, notes and illustrations.
