Starting all the way back in 2008, SecurityTube was created by fellow security researcher Vivek Ramachandran, a trusted professional in the security industry.

LEAP (site defunct, will be updated shortly), the last free website to learn hacking on the list is another great website with several free cyber-security courses spanning a variety of subjects. Various topics consist of cyber security fundamentals, cyber forensics fundamentals, cyber law and even countering cyber attacks.

LEAP offers various great courses for beginners, our favorite being cyber security fundamentals, a well-structured course that can get you on your way to learning hacking and security basics from the ground up.

Typically, courses on Udemy cost money, but we’ve found a few worth checking out that won’t put a dent in your bank account. There’s a Cybersecurity Law primer, for example, that we think could be beneficial to anyone wanting to know the ins and outs of cybersecurity ethics. 

The Cyber Security Course for Beginners – Level 01 could also be advantageous to take, not only for cybersecurity enthusiasts but for anyone who wants to learn more about the subject. 

However, Udemy’s real selling point is that not only does it offer some very in-depth courses, but many of these courses can also be bought on offer for less than $20, making them extremely cost-effective. 


Coursera offers a range of short courses for distance learning, including a number of cybersecurity ones such as Cybersecurity Specialization which was created by the University of Maryland to bring the underlying concepts of the construction of secure systems directly to your web browser. 

It consists of five courses in total, each of which can take several weeks to complete. These range from Usable Security to a Cybersecurity Capstone Project, so it’s safe to say that they’ll require you to already have some intermediate cybersecurity know-how under your belt.

There are additional cybersecurity courses available, though, covering everything from the basics to more advanced specializations.
