Chapter 1: A Refresher on Defensive Security Concepts

Cybersecurity is no longer an exclusive matter of the IT department, it is increasingly an issue that needs to be understood by the company's leadership and a challenge that involves the awareness and knowledge of each of the members of the organization.

Understanding the core cybersecurity concepts is key to becoming a master. A master is not just defined by their experience in relation to a given technology, but also by their deep understanding of the topics and the proper use of the technological jargon and concepts.

As a cybersecurity expert, you may be engaged by the media who want to know more about the latest attack, or called by the government to be part of a team of advisors in cybersecurity. In both cases, you will have to be prepared to speak up and provide your expert opinion, and this chapter will prepare you to be so well-grounded in cybersecurity concepts that you are able to speak as a master!

As part of this journey, we're going to cover the following main topics:

  • A deep dive into the core of cybersecurity
  • Managing cybersecurity's legendary pain point: Passwords
  • How to master defense-in-depth
  • A comprehensive explanation of the Blue and Red teams
