The task for today:
Read and Learn about Ethical hacking
My way to learn about the topic was to read the story how Troy Hunt started his career in web security and how he became a content creator for ethical hacking certifications. After reading the story you may want to browse other articles written by him.
Another great thing (even I do not agree to everything, it is still very good) created by Troy: Internet Security Basics for those, not so much into security.
