About the list:
---------------
For everyone in the Information Security business, it's important to understand the enemy, the hacker. Understanding the enemy makes you the best defender you can be to secure the digital world.

> By knowing your enemy, you can defeat your enemy. 

In the USA, the most senior police officers, even long after their pension, are advising residents how to secure their homes better. They come to your house and tell you where your weak points are around the house. They can advise this because they KNOW their enemy, the criminal that wants to break into the house and his techniques.

Training your cyber skills means also keeping your hacking skills up to date. To do this, you need an environment to practice in, free, legally and safely.

For this purpose, I have made a list of websites you can visit and practice your cyber skills. Every site has a different angle on the whole thing, so I'll summarize in a couple of words its specifics.

Some sites will offer you tutorials to help you, others will require you to find things on your own.

I will update this post below regularly and add sites to this post so bookmark it and/or follow me to see the latest overview. 

If you are missing a site not mentioned in the list, feel free to [contribute](https://github.com/joe-shenouda/awesome-cyber-skills/blob/master/CONTRIBUTING).
