Web application security

Tanfolyam célja

As a developer, your duty is to write bulletproof code. However...

What if we told you that despite all of your efforts, the code you have been writing your entire career is full of weaknesses you never knew existed? What if, as you are reading this, hackers were trying to break into your code? How likely would they be to succeed? What if they could steal away your database and sell it on the black market?

This Web application security course will change the way you look at code. A hands-on training during which we will teach you all of the attackers’ tricks and how to mitigate them, leaving you with no other feeling than the desire to know more.

It is your choice to be ahead of the pack, and be seen as a game changer in the fight against cybercrime.
