Data breach notification is the legal obligation to inform affected people, and in some cases regulators, when their personal data is exposed in a security incident. The notice must explain what happened, which data was affected and what steps to take, within the deadlines set by each applicable law, such as US state breach notification laws, HIPAA or GDPR.
