Comprehensive and Detailed Explanation From Exact Extract:
Data breach notification laws for personally identifiable information (PII) generally require organizations to provide timely notification to (1) regulatory authorities (regulators/data protection authorities) and (2) affected individuals (customers/data subjects), within legally mandated timeframes.
The Secbay Press CySA+ CS0-003 guide explicitly describes this requirement in multiple places:
Regulatory reporting + notifying affected individuals:Exact extract (Secbay Press): “Reporting the incident to regulatory authorities and notifying affected individuals in accordance with… privacy laws…”
Timeliness is required by law:Exact extract (Secbay Press): “Timeliness of Reporting: Adhering to stipulated timeframes for reporting incidents…”
Customers/affected individuals must be notified within the legally mandated timeframe:Exact extract (Secbay Press): “Sending notifications to customers within the legally mandated timeframe after confirming a data breach.”
These extracts directly support Option D: Regulators and affected customers.
Why the other options are incorrect
A (Service providers and business associates): Those relationships may have contractual notification requirements, but breach notification laws for PII focus on regulators and affected individuals.
B (Law enforcement and the media): These may be involved depending on incident type/requirements, but they are not universally required recipients under PII breach notification laws.
C (CERTs and industry associations): These are optional coordination entities, not mandated recipients for PII breach notification laws.
