The requirements for archiving data and immutable backups directly align with legal hold compliance (E) and ransomware resilience (F).

Legal hold compliance ensures that organizations can retain data in a tamper-proof manner when required for litigation, regulatory mandates, or audits. Immutable backups satisfy this by preventing unauthorized changes or deletion, ensuring evidence and records are preserved.

Ransomware resilience is also a key factor. Immutable backups allow recovery from ransomware attacks, as attackers cannot encrypt or delete data stored in read-only or write-once media. This reduces downtime and supports business continuity.

Options A (crypto-export), B (supply chain), C (device attestation), and D (quality assurance) do not relate directly to data archiving or immutable storage.

CAS-005 stresses aligning security controls with business continuity and compliance requirements. By focusing on legal and ransomware-related considerations, the organization ensures both regulatory and operational resilience.
