ある組織が、資本計画と報告機能をサポートする社内ソフトウェアプラットフォームを開発しています。製品マネージャーは、ロールベースのアクセス制御と監査/ログ機能に加えて、データのアーカイブと変更不可能なバックアップに関する要件も考慮する必要があります。この要件に関連する組織上の考慮事項として最も可能性が高いのはどれですか(2つ選択してください)。
正解:E,F
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.
