A multinational retail enterprise headquartered in Texas processes online orders for customers residing across the European Union. During an operational risk assessment, the chief information security officer observes that customer transaction logs—which include payment details, IP addresses, and email addresses—are continuously replicated to a centralized data warehouse in Dallas. The IT infrastructure team asserts that encrypting the database at rest using AES-256 satisfies all legal security duties. However, the legal compliance team insists this control is insufficient for international data flows. Which of the following best describes the organization's legal compliance obligation regarding these data transfers?
- The organization must implement an approved cross-border data transfer mechanism, such as Standard Contractual Clauses or an adequacy decision framework, because technical encryption alone does not fulfill statutory data privacy requirements for legal data transfers.Cevap
- BAchieving PCI-DSS compliance for payment transactions legally preempts and overrides regional data privacy mandates, exempting transactional IP logs from cross-border transfer restrictions.
- CRelocating all physical servers to an EU member state is strictly mandated by law, as international cross-border transfers of customer IP addresses are explicitly prohibited.
- DOffloading payment processing to a third-party payment service provider transfers all statutory compliance liability away from the data controller for remaining web interaction logs.
Cevap
The organization must establish an approved cross-border data transfer legal mechanism (such as Standard Contractual Clauses or an adequacy framework) because technical security measures such as encryption at rest do not satisfy statutory privacy rules governing international data movements.
Technical security controls like AES-256 encryption address data security (protecting confidentiality), but do not fulfill legal data privacy requirements regarding international data sovereignty. Frameworks like the EU GDPR mandate that transferring personal data (including IP addresses and contact details) outside the native legal jurisdiction requires a valid legal transfer framework, such as Standard Contractual Clauses (SCCs) or an adequacy framework.
