Which statement about data transmission over the public network is true?

• A. Data over private networks can be intercepted.
• B. Data over public networks can be intercepted, modified, and/or diverted while in transit.
• C. Public networks are always secure.
• D. Proxy servers guarantee data privacy.

Answer: (B)

Transmitting data over public networks introduces risks to both confidentiality and integrity, because the data travels through shared, potentially insecure paths that others can access. The statement that traffic on public networks can be intercepted, modified, and/or diverted while in transit accurately describes the real threats you face in those environments. That’s why protections like encryption (TLS/HTTPS, VPNs), strong authentication, and integrity checks are essential to prevent eavesdropping, tampering, or redirection of data. The other options don’t fit: data on private networks can still be exposed if a component is compromised, public networks aren’t inherently secure, and proxy servers do not guarantee privacy by themselves.
