About the Book

Are you looking to enhance your knowledge and become a more proficient cybersecurity engineer? Or perhaps you are new to the field and eager to learn the fundamentals?

The story behind the book:

Many companies are interviewing candidates for junior cybersecurity engineer positions who express an interest in the field but lack basic knowledge and understanding. This phenomenon is observed not only among IT engineers seeking to transition into cybersecurity roles, but also among fresh university graduates who may not have received adequate education in cybersecurity.

To identify the best fit for a team and the culture, many companies assess candidates based on their willingness to learn and take calculated risks, often relying on their instincts. Once selected, they create a tailored training path for the candidate with the hope that they will enjoy the journey, develop a passion for cybersecurity, and become proficient engineers and cybersecurity experts who contribute to the company and increase productivity.

In some cases, the provided training includes basic cybersecurity concepts, networking, techniques, technologies, methodologies, threats, attacks, vulnerabilities, tools, and more. While some candidates may only require a quick refresher if they have received prior education in these areas, many others need to learn from scratch. The training sessions can be time-consuming, taking away from productive work, and need to be repeated for new hires.

To address this gap, you may use this book that covers the fundamental knowledge required to kickstart or refresh one’s understanding in cybersecurity.

If you are aspiring to enter the field of cybersecurity, we encourage you to explore the book and gain a solid understanding of the fundamentals. Refresh your knowledge, practice with labs, and equip yourself with the necessary skills to secure a job in this field or become a better engineer.

For companies, this book can serve as a valuable guide to provide to newly hired employees, helping them get started in their roles with a solid foundation of knowledge.

Furthermore, this book is a comprehensive guide to answering core cybersecurity questions that may arise during job interviews for a cybersecurity engineer or consultant position. It covers essential concepts and terminology expected to be known and understood by candidates, helping them become more confident in describing and demonstrating their knowledge during interviews. With this book, readers can verify their knowledge before their interview, identify areas they need to strengthen, and gain a solid understanding of fundamental cybersecurity concepts, including networking, security systems, operating systems, attacks, threats, and certifications, among others.
