FAQ

Is it legal to hack systems for learning?

Only with written authorization. Unauthorized access is illegal regardless of intent. Practice in your own lab or with explicit written permission.

What happens if I find a vulnerability without authorization?

Report it responsibly through proper channels. Don’t exploit it. Follow responsible disclosure process. Document everything.

Can I test my employer’s systems without permission?

No, always get written authorization. Even as an employee, unauthorized testing is illegal. Follow your organization’s security testing policies.

What’s the difference between ethical hacking and illegal hacking?

Ethical hacking has written authorization. Illegal hacking is unauthorized access. Intent doesn’t matter—authorization is the key difference.

How long should I wait before public disclosure?

Typically 90 days after initial report, but coordinate with vendor. Complex vulnerabilities may need more time. Document timeline and communications.

What should I do if I’m asked to do something unethical?

Decline and explain why. Document the request. Seek guidance from ethics committee or legal counsel. Report ethical violations if necessary.

Are bug bounty programs legal?

Yes, if properly structured with clear terms and authorization. Read terms carefully. Follow program rules. Report responsibly.
