Which term denotes a legal channel for transferring data securely within a company network?

• A. Trojan Proxy
• B. IExpress Wizard
• C. Overt Channel
• D. Covert Channels

Answer: (C)

In security, data transfer paths are classified as overt versus covert. An overt channel is a legitimate, authorized path for moving data that is clearly visible to security controls, monitored, and enforceable by policy. In a company network, this means the data flows through approved services and protocols (like secure file transfer, encrypted links, or VPNs) that are documented and auditable. This transparency and authorization make it a trusted channel for securely transferring information. The other options don’t fit this idea. A Trojan Proxy is malware designed to route traffic through an attacker-controlled path, which is not a legal or approved channel. An IExpress Wizard is a tool for creating self-extracting installers, not a data transfer channel. Covert channels are exactly the opposite of overt channels: hidden methods used to secretly exfiltrate or transfer data, bypassing controls.
