IIBA-CCA 問題集 練習問題・模擬試験｜日本語版＆英語版対応

Explanation: Data is commonly categorized into three states because the threats and protections change depending on where the data is and what is happening to it. Data at rest is stored on a device or system, such as databases, file shares, endpoints, backups, and cloud storage. The main risks are unauthorized access, theft of storage media, misconfigured permissions, and improper disposal. Controls typically include strong access control, encryption at rest with sound key management, secure configuration and hardening, segmentation, and resilient backup protections including restricted access and immutability. Data in transit is data moving between systems, such as client-to-server traffic, service-to-service connections, API calls, and email routing. The primary risks are interception, alteration, and impersonation through man-in-the-middle techniques. Standard controls include transport encryption (such as TLS), strong authentication and certificate validation, secure network architecture, and monitoring for anomalous connections or data flows. Data in use is actively processed in memory by applications and users, for example when a document is opened, a record is processed by an application, or data is displayed to a user. This state is challenging because data may be decrypted for processing. Controls include least privilege, strong authentication and session management, endpoint protection, application security controls, and secure development practices, with hardware-backed isolation when required

Explanation: The GDPR establishes a regulatory penalty framework intended to make privacy and data-protection obligations enforceable across organizations of any size. Under GDPR, the most severe administrative fines can reach up to 20 million or up to 4% of the organization’s total worldwide annual turnover of the preceding financial year, whichever is higher. That “whichever is greater” clause is critical: it prevents large enterprises from treating privacy violations as a minor cost of doing business and ensures the sanction can scale with the organization’s economic size and risk impact. Cybersecurity governance and risk documents typically emphasize GDPR as a driver for enterprise risk management because the consequences extend beyond monetary fines. A confirmed violation often triggers regulatory investigations, mandatory corrective actions, and potential restrictions on processing activities. Organizations may also face indirect impacts such as breach notification costs, legal claims from affected individuals, reputational harm, loss of customer trust, and increased oversight by regulators and auditors. From a controls perspective, GDPR penalties reinforce the need for strong security and privacy-by-design practices: data minimization, lawful processing, documented purposes, retention controls, encryption where appropriate, access control and least privilege, monitoring and incident response readiness, and evidence-based accountability through policies, records, and audit trails. Selecting option C correctly reflects GDPR’s maximum fine structure and its risk-based deterrence model.

Explanation: In the United States, HIPAA, the Health Insurance Portability and Accountability Act, is the primary federal framework that governs how certain healthcare information must be protected and used. In cybersecurity and compliance documentation, HIPAA is most often discussed through its implementing rules, especially the Privacy Rule and the Security Rule. The Privacy Rule establishes when protected health information may be used or disclosed and grants individuals rights over their health information. The Security Rule focuses specifically on safeguarding electronic protected health information by requiring administrative, physical, and technical safeguards. From a security controls perspective, HIPAA-driven programs typically include risk analysis and risk management, policies and workforce training, access controls based on least privilege, unique user identification, authentication controls, audit logging, integrity protections, transmission security such as encryption for data in transit, and contingency planning such as backups and disaster recovery. HIPAA also expects organizations to manage third-party risk through appropriate agreements and oversight when vendors handle protected health information. The other options do not fit the question. The Privacy Act generally applies to U.S. federal agencies’ handling of personal records, PIPEDA is a Canadian privacy law, and PCI-DSS is an industry security standard focused on payment card data rather than healthcare data. Therefore, HIPAA is the correct legislation for U.S. healthcare data protection requirements.
