COSO (Committee of Sponsoring Organizations of the Treadway Commission): A widely accepted framework for designing and implementing internal controls in business organizations. The COSO framework addresses organizational governance, risk management, and business ethics and has become a globally recognized standard for managing and controlling risk in various domains.

Cost/benefit analysis: A decision-making process often used in business and organizational settings to determine the feasibility and value of a proposed action or solution. It involves a thorough evaluation of the expected costs and potential benefits of an initiative. In the context of risk management, a cost/benefit analysis might be used to weigh the investment in security measures against the potential losses from security incidents.

Countermeasure: A tactic, procedure, or technique that is applied to prevent, mitigate, or eliminate vulnerabilities, threats, or attacks. This could be a wide range of actions, such as installing a firewall to block unauthorized access, implementing encryption algorithms to secure data, or deploying intrusion detection systems to identify potential security breaches. Countermeasures are crucial for maintaining the confidentiality, integrity, and availability of data and systems.

Coupling: In the context of software design, coupling refers to the degree to which one module or component depends on another. High coupling indicates that a change in one module may require changes in other modules, while low coupling allows for a more modular and independent design.

Covert Channel: A communication channel that enables information transfer in a way that violates security policies, typically by using mechanisms that were not originally intended for communication. This can include using system properties or resources (like processor usage or file modification times) to covertly transmit information, enabling entities to communicate surreptitiously without detection.

Covert Channel Analysis: The process of examining systems to identify and mitigate covert channels. This process involves reviewing system design and operations to uncover unintended communication paths that could be exploited for unauthorized information transfer. It's a crucial component of comprehensive security audits and assessments, particularly in high-security environments.
