The statement 'Open networks can be legally accessed by anyone and are frequently posted as such' is true or false?

• A. Cannot be Determined
• B. Sometimes
• C. False
• D. True

Answer: (C)

The key idea is that permission governs access, not just the absence of authentication. Just because a network is unprotected (open) doesn’t automatically grant legal access to anyone. The network owner sets who may use it and under what terms, and violating those terms or laws can still make access unauthorized. In many places, unauthorized access to a network is illegal even if there’s no password, and open networks may come with usage policies or limitations. So the statement isn’t universally true; openness doesn’t guarantee legal access.
