A RACI Matrix is a project management tool used in cybersecurity and other fields to clarify roles and responsibilities for tasks or processes. RACI stands for Responsible, Accountable, Consulted, and Informed. By mapping out who is responsible for completing a task, who is accountable for its outcome, who needs to be consulted for input, and who should be kept informed, organizations can avoid confusion and ensure efficient collaboration. In cybersecurity, a RACI Matrix helps define clear ownership for critical activities such as incident response, risk assessments, and compliance tasks, reducing the risk of oversight or duplicated effort.
