Cybersecurity encompasses various fields in technology and computing, each with its own set of skills. It is a deep field, with concepts, tools, and techniques that one must master to get a good foundation to understand domain-specific topics like penetration testing.
Learning cybersecurity can be achieved in three ways: top-down, bottom-up, and project-based. However, the most effective approach is through an apprenticeship, as it provides a structured, hands-on learning environment.
During the apprenticeship, you will work as a script kiddie (aka skiddie) to learn from experienced practitioners. This approach saves a lot of time compared to other learning methods. However, finding an apprenticeship is not easy as most skilled practitioners are busy or not interested.
An alternative way to learn cybersecurity is through on-the-job training, where you work alongside co-workers with more experience, and learn by observing and asking questions.
Using a bottom-up approach in cybersecurity can make it easier to learn new fields. Research indicates that active recall, such as project-based learning, is more effective than passive study for building strong memories.
Cybersecurity is complex and takes a long time to master, similar to becoming a doctor or lawyer. In the United States, it takes four years of medical school followed by three to seven years of residency to become a licensed physician. In contrast, becoming a professional in cybersecurity does not necessarily follow an institutionalized path. It requires self-education and the combination of different learning approaches to achieve mastery.
