Reporting in investigations: The systematic documentation and communication of the findings and outcomes of an investigative process, typically involving a security incident or breach. This can include information about the nature and cause of the incident, the systems or data affected, the methods used in the investigation, and the proposed remedial actions. It is a crucial part of an effective incident response strategy, as it aids in accountability, regulatory compliance, and the development of preventive measures for future incidents.

Reporting on security controls: The process of documenting and communicating the effectiveness of security controls to relevant stakeholders. This is used in organizations to ensure compliance with security regulations and standards and to identify areas for improvement. For example, an annual security audit may include a report on security controls, and a security team may provide regular updates on control effectiveness to management.

Repository: A central location in which data is stored and managed. In terms of software development, it's often used to manage and store different versions of code files. A repository can be local to a user's machine, or it can be a storage space on a server or on the cloud. Repositories are crucial in maintaining data integrity, version control, and facilitating collaboration among multiple users or teams.

Representation (in IT and Cybersecurity): The depiction of data or processes through understandable symbols or models, for example, using visual schematics to represent network structures or encoding data in formats that ensure confidentiality and integrity. Accurate representation is vital for effective analysis, communication, and protection of IT assets.

Repudiation: The denial by an individual or entity of having performed a particular action related to data or a transaction. Non-repudiation measures counter this by providing evidence of origin or delivery that cannot be disputed by the involved parties.

Reputation risk: The potential damage to the standing of an individual or entity due to a particular event, action, or inaction, which could result in a loss of trust among stakeholders, customers, or the public. In terms of security, it's the risk of damage to a company's reputation that could result from a data breach, system failure, or other security incident. Managing this risk involves a combination of proactive security measures, effective incident response, and communication strategies.
