Ethical Hacking is a really interesting field to be working in.
Ethical hacking is conducted by hackers as well but their intention behind hacking is not for malicious purposes. Their services are used to check and build on software security and thus help to develop the security system of a framework in a business or organization to prevent potential threats. Ethical hackers are referred to as White Hat Hackers.
I would suggest you to read extensively about what does ethical hacking include, the techniques that are used, and other such stuff.
You could start with simple blogs like https://www.edureka.co/blog/what-is-ethical-hacking/#What-is-Ethical-Hacking
You could check out a couple of youtube videos as well.
I also found this course of Cybersecurity and ethical hacking that's really useful.
