Computing is a field of scientific, technical and industrial activity concerning the automatic processing of information by the execution of computer programs by machines: embedded systems, computers, robots, automatons, etc.

These fields of application can be separated into two branches, one of a theoretical nature, which concerns the definition of concepts and models, and the other, of a practical nature, which deals with concrete techniques of implementation. . Some areas of computing can be very abstract, like algorithmic complexity, and others can be closer to a lay audience. Thus, language theory remains a field more accessible to trained professionals (description of computers and programming methods), while professions related to man-machine interfaces are accessible to a wider audience.

The computer term results from the association of the information term with the suffix "-ique" meaning "which is specific to". As an adjective, it applies to all processing related to the use of computers and digital systems. As a noun, it designates the activities related to the design and implementation of these machines. Telecommunications issues such as signal processing or information theory, as well as mathematical problems such as computability are attached to it. In American university vocabulary, ?computer science? refers above all to theoretical computer science: a set of formal sciences whose object of study is the notion of information and the processes for automatically processing it, algorithmic.

Computer applications since the 1950s have formed the basis of the information and communication technology industry. This industrial and commercial sector is linked to both processes (software, system architectures) and hardware (electronics, telecommunications). The sector also provides many services related to the use of its products: development, maintenance, education, support, monitoring and servicing.

Cyber security is hard to learn because of its depth and breadth. There’s a multitude of fields, each with unique tools and concepts to learn. Each of these sub-fields contains, yet again, even more topics! As a beginner, the vast complexity can be quite overwhelming. Fortunately, there’s two secrets to tackle this:

First, you need to discover what topics cyber security comprises. Then narrow your scope to the ones that you’re super interested in. Master one area first before expanding to others. For some, you may decide to focus on this area, doing deeper over an entire career. For others, it might be more fulfilling to branch out and build expertise in several other topics.

Second, change your expectations for learning. Mastery of any skill requires persistence and a long-term time horizon. For many, it’s tempting to seek out a crash course or quick guide and expect to get results. The truth is that it takes thousands of hours to achieve proficiency. Cyber security takes dedicated training, just like any other profession. Doctors, for instance, need 4 years of medical school and 3-7 years of apprenticing in a residency.

Having the right mindset, you can overcome any challenge. The second piece you need is an effective learning strategy for cyber security. Here’s the three:

Method #1: Top-down.

The top-down method involves selecting a specific skill and learning it directly. This approach is best used via an apprenticeship. Proper tutelage under a senior or master practitioner can reduce the time-to-proficiency drastically.

Method #2: Bottom-up approach.

For many apprenticeships, you’re expected to have a solid baseline first. A bottom-up approach breaks topics down into fundamental components. The process may often involve reading lots of cyber security books and articles. Mastering the basics first can make it much easier to pick up on more high-level concepts.

Method #3: Project-based.

This approach is a hybrid of the previous two. First you define a technical goal and then collect the resources needed to achieve it. Pursuing projects will expose you to many skills top-down learning may not cover. It also makes bottom-up learning less monotonous and boring.

As of today, there isn’t an institutionalized path towards learning cyber security. Other professions (doctors, lawyers, accountants) have it much easier, in this regard. Hence, you really have to take the education path into your own hands. With the right mindset and strategy, you’ll get there in no time.

Level Up.
