What is the term for a communications pathway that can violate security policies by transferring information?

The term that describes a communications pathway capable of violating security policies by transferring information is a covert channel or covert path. This concept refers to a method of communication that allows data to flow between entities in a way that is not authorized or intended, often circumventing established security controls.

Covert channels exploit weaknesses in a system to leak information, potentially leading to breaches of confidentiality. For instance, a covert channel may utilize legitimate communication mechanisms in a manner not intended by the system's design, allowing one user to send information to another in a manner that is hidden from the system's security mechanisms.

Entities designing security systems need to be aware of covert channels to ensure they can mitigate these risks effectively. By understanding how covert channels can be utilized, organizations can implement stronger security measures that prevent unauthorized information disclosure, even if it means revisiting their policies and technical implementations to close off such pathways.

The other options do not accurately represent this specific security concern. Public channels are intended for legitimate communication, open paths suggest accessibility without restrictions, and data pipelines indicate structured pathways for data flow without implying any violation of policies.
