Free Cybersecurity Resources
There is a collection of knowledge out there, with much of it being free.
I put together some resources for Cybersecurity in this post.
Command Line Kung Fu
A blog I have recommended to people wanting to get their hands dirty with the command line. It goes over specific problems and solving them from the command line. It focuses on the “how”, with explanations on solutions from experts in the field.
Coursera
A MOOC (massive open online course). It has plenty of options for Information Security and courses are free when you audit them. This gives you the same access as paying, just no certificate when you complete it. In the end, the knowledge you retain will be more important than certificates or certifications.
CyberDefenders
This is another hands on platform with Capture the Flags. It has various challenges in security topics and sets of questions to go through. What is unique about this one is it is focused on the Blue team side of things, and can get quite granular.
Also of note here, some of the exercises on this platform are similar to interview exercises you may see.
edX
edX is another MOOC (massive open online course) with course options in cybersecurity.
Like Coursera, it has instructor led courses from top universities.
Some of the universities they partner with for courses include Harvard, MIT, and Berkeley.
OverTheWire
This is a CTF platform (Capture the Flag) with various challenges in security topics and sets of questions to go through.
Bandit for example, takes you through the command line from basically zero and levels you up by the end, with challenges increasing in difficulty as you go.
Udemy
Udemy is another MOOC (massive open online course).
However, these courses are generally made by practitioners and not Colleges or Universities such as Coursera. It has tons of courses both free and paid, including my free course on Linux Fundamentals. I always recommend folks to learn Linux well for Cybersecurity, and I hope you get a lot of value out of it.
Awesome Compilations
Lastly, this “hack” will work for any Cybersecurity domain and even other domains in tech.
Searching the phrase awesome “literally any security domain” will give you Github compilations of resources for that given topic. Github is a great resource in general, but using this keyword search will provide immense value.
For example awesome “pentesting” or awesome “blue team” or awesome “macos security”. Even if you don’t include github in your search it should be the top result in google.
Wrapping Up
These are some of the many free resources out there, and I encourage you to check them out, to find what interests you the most. At the end of the day, it doesn’t cost you anything.
I hope this overview of resources helps you in your learning journey!
