Overt Channel: An overt channel is a standard, open, and legitimate path for communication within a computer system or network. It is utilized to transfer data as intended by its design and is often monitored for security purposes. This term should not be confused with a covert channel, which is a pathway that is used for unauthorized transmission of information within a computer system.

Overwrite Procedure: A method of securely deleting data from a storage device to prevent its recovery. It is commonly used in data destruction and cybersecurity to prevent sensitive information from falling into the wrong hands. Examples of overwrite procedures include the DoD 5220.22-M standard and the Gutmann method.

Owner: The individual or entity that has legal rights and control over a data resource or an asset. They are responsible for defining the classification of the data, access controls, and ensuring appropriate protection mechanisms are in place to safeguard the integrity, confidentiality, and availability of the data.

Ownership of cloud data: Ownership of cloud data refers to the legal and contractual rights and responsibilities regarding data stored in cloud environments. It determines who has control over the data, who can access it, and who is liable for its protection. This is particularly crucial in cloud services agreements, where the delineation of data ownership affects how data is managed, shared, and secured in the cloud.
