How to Learn Ethically and Legally?

Cyber security is about protection and trust. Practise only in environments that you own or have clear written permission to test. Never run tests on systems that are not yours. If you like challenges, try legal platforms like capture-the-flag (CTF) competitions and vendor-approved labs. Remember: good security professionals follow the law and respect privacy.
