Mastering Defensive Security

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.

– Rogelio Umaña - Senior Partner | Digital Transformation for RDP Consulting

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

Technical requirements

There are no technical requirements for this chapter, but you may need a cup of Java (to prepare your brain for the tons of knowledge that you are about to receive).

Now, let's get ready for our learning adventure.

Description

Every organization has its own data and digital assets that need to be protected against an ever-growing threat landscape that compromises the availability, integrity, and confidentiality of crucial data. Therefore, it is important to train professionals in the latest defensive security skills and tools to secure them. Mastering Defensive Security provides you with in-depth knowledge of the latest cybersecurity threats along with the best tools and techniques needed to keep your infrastructure secure.

As you make progress through the chapters, you'll get to grips with several advanced techniques such as malware analysis, security automation, computer forensics, and vulnerability assessment, which will help you to leverage pentesting for security. By the end of this book, you'll have become familiar with creating your own defensive security tools using IoT devices and developed advanced defensive security skills.

Another great book published by Packt!Mastering Defensive Security by Cesar Bravo, MSc is a very thorough digest on the concepts, strategies, and techniques to secure Windows, Linux, IoT, OT, and Cloud resources.This book is a beast. It covers best practices, hygiene, asset management, vulnerability management, and risk management as concepts and then shows how to implement them in an organization. It gives background and then hands-on directions for CLI and GUI tools. It covers Active Directory. It covers hybrid cloud.It's a lot. If you are building a cybersecurity program or want your technicians and analysts to start implementing controls and harden systems, then this is the book for you. I gotta say, I thought it was a nice refresher for myself. Because of the breadth of content, I got a nice reminder of some things I haven't touched in a while.And it's easy to read. So many technical books have the ability to put you to sleep before you learn anything useful. That's not the case here. It's not fluff. It's just engaging and useful.

"Mastering Defensive Security" is a comprehensive and practical guide for readers interested in bolstering their digital defenses against cyber threats. The book covers a wide range of security topics, making it suitable for beginners and experts alike, and emphasizes a proactive, layered defense approach. It provides valuable insights and real-world examples, although it might be somewhat challenging for absolute beginners, and some of the mentioned technologies could become outdated. Overall, it's a must-read for those serious about enhancing their cybersecurity skills and safeguarding their digital assets.
