About Our Online Cyber Security Classes

Cyber Security jobs are growing three times faster than information technology jobs. However, this rapidly growing and very exciting industry lacks the number of skilled professionals required to handle the jobs. Some common  jobs within Cyber Security include information assurance, security analyst, penetration tester, malware analyst/reverse engineering and Intel. With these types of opportunities available, aspiring or growing Cyber Security professionals should focus on continually increasing their skill set, because the Cyber Security industry never rests, it is continually changing. However, traditionally, Cyber Security classes are the most expensive training classes. As you know, that barrier to entry has been removed.

Cyber Security training of all skill levels is now free so that the aspiring Cyber Security professionals can begin their career and those already in the field can become better and expand their opportunities. Together, we can contribute to everyone’s ability to learn. In the free training classes below, we ask that you contribute, discuss on the forums, share information and participate in helping others learn.

Some of the more advanced Cyber Security training classes can be very hard to find, but at Cybrary we are continually looking to add more.

Which Cyber Security Course is Best?

When trying to decide which cyber security course on Cybrary is best for you, it is important to consider what you would like to gain from that course. For someone with little to no knowledge of cyber security, it is necessary for you to begin by learning the fundamentals, as these will be essential in future courses. In order to build a solid foundational knowledge of cyber security, the best courses to begin with are CompTIA A+ and CompTIA Network+. These two courses will give you the basic knowledge you need to decide which path in cyber security best suits your interests, and with which courses to proceed.

If you already possess this basic knowledge and are looking to advance your career to an intermediate level, then the best course for you to begin with is Security+. Security+ touches on the several branches of cyber security and will give you the information you need to decide on a specific advanced course path from there. Each course at Cybrary is taught by professionals who know their topics inside and out. No matter which path you choose, here at Cybrary we can guarantee you quality material at every level.

Why Cyber Security Training is Important?

Cyber Security training is important for several reasons. Technology is integrated into nearly every aspect of modern life; from our jobs, to our phones, to our cars and homes. As smart technology advances, the ways in which our lives can be greatly impacted by cybercrime increase dramatically. Unfortunately, the scope of the issue is often overlooked. This is because when we think of cybercrime and hacking, we tend to think of what makes national headlines, such as mass identity theft and stock manipulation. In reality there are countless ways that cyber-crimes can affect both your personal and business life, and it is important to realize that the worst outcome of these crimes isn’t always monetary loss.

Imagine a time in the near future when the majority of the population owns self-driving cars. Now imagine the potential damage resulting from a breach in the cyber security of even one of those car companies. This is just one example of the many ways in which improper training, or general lack of training, could prove to be both costly, and deadly. In a world in which technology continues to advance exponentially, the more pertinent question is, in what way is cyber security training not important?
