Insecure communications refers to which practice?

• A. Using TLS for all traffic
• B. Employing a VPN
• C. Transmitting sensitive data without encryption
• D. Encrypting data in transit

Answer: (C)

Insecure communications means sending sensitive information over a network without any protection. When data travels unencrypted, anyone who can intercept the traffic—whether on a local network, a public Wi‑Fi, or between services—can read it and potentially alter it. Encrypting data in transit, using TLS for web traffic, or tunneling through a VPN, protects against eavesdropping and tampering, which is why those practices are considered secure. Transmitting sensitive data without encryption is the insecure practice because it leaves the information exposed to unauthorized access.
