Mandatory Reporting: A requirement, often established by law, regulation, or industry guidelines, which obligates individuals or organizations to report certain types of incidents or data breaches to relevant authorities within a specified timeframe. In cybersecurity, mandatory reporting typically involves notifying government bodies, regulatory agencies, affected individuals, or other stakeholders about security incidents that could potentially lead to the exposure of sensitive, confidential, or personally identifiable information. The goal of mandatory reporting is to ensure timely and transparent communication about breaches, enabling prompt response and mitigation efforts to protect affected parties and prevent future occurrences.
