Explanation:

The core distinction between ethical and criminal hackers lies in authorization. Ethical hackers (also called white hats) are explicitly permitted by system owners to test security, while criminal hackers (black hats) access systems without permission for malicious or self-serving purposes. The other options are incorrect: neither type is "all-knowing," detection risk is not a defining difference, and personal demeanor does not separate the two categories.

Answer:

An ethical hacker has permission to hack a system, and a criminal hacker doesn't have permission.
