質問 # 63
Controls that are put in place to address specific risks may include:
正解：B
解説：
Cybersecurity controls are the safeguards an organization implements to reduce risk to an acceptable level. In standard risk-management language, a control is not limited to a one-time review; it is an ongoing capability that is designed, implemented, and operated to prevent, detect, or correct unwanted events. That capability is typically delivered through technology solutions (technical controls) and process solutions (administrative or procedural controls), which is why option B is correct.
Technology controls include items like firewalls, endpoint protection, encryption, multifactor authentication, logging and monitoring, vulnerability scanning, secure configuration baselines, and data-loss prevention. These controls directly enforce security requirements through system behavior and automation, helping reduce the likelihood or impact of threats.
Process controls include policies, standards, access approval workflows, segregation of duties, change management, secure development practices, incident response playbooks, training, and periodic access recertification. These ensure people consistently perform security-critical tasks correctly and create accountability and repeatability.
Options C and D describe possible outcomes or limitations (controls may not fully eliminate risk and may only mitigate part of it), but they are not what controls include. Option A is incorrect because "only initial reviews" are insufficient; reviews can be a component of a control, but effective controls require sustained operation, evidence, and reassessment as systems, threats, and business needs change.
質問 # 64
What privacy legislation governs the use of healthcare data in the United States?
正解：D
解説：
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.
質問 # 65
Which scenario is an example of the principle of least privilege being followed?
正解：D
解説：
The principle of least privilege requires that users, administrators, services, and applications are granted only the minimum access necessary to perform authorized job functions, and nothing more. Option A follows this principle because the administrator's elevated permissions are limited in scope to the specific applications they are responsible for supporting. This reduces the attack surface and limits blast radius: if that administrator account is compromised, the attacker's reach is constrained to only those applications rather than the entire enterprise environment.
Least privilege is typically implemented through role-based access control, separation of duties, and privileged access management practices. These controls ensure privileges are assigned based on defined roles, reviewed regularly, and removed when no longer required. They also promote using standard user accounts for routine tasks and reserving administrative actions for controlled, auditable sessions. In addition, least privilege supports stronger accountability through logging and change tracking, because fewer people have the ability to make high-impact changes across systems.
The other scenarios violate least privilege. Option B grants excessive enterprise-wide permissions, creating unnecessary risk and enabling widespread damage from mistakes or compromise. Option C provides "just in case" administrative access, which cybersecurity guidance explicitly discourages because it increases exposure without a validated business need. Option D is overly broad because access to all HR files exceeds what is required for performance appraisals, which typically should be limited to relevant employee records only.
質問 # 66
What is an embedded system?
正解：B
解説：
An embedded system is a specialized computing system designed to perform a dedicated function as part of a larger device or physical system. Unlike general-purpose computers, embedded systems are built to support a specific mission such as controlling sensors, actuators, communications, or device logic in products like routers, printers, medical devices, vehicles, industrial controllers, and smart appliances. Cybersecurity documentation commonly highlights that embedded systems tend to operate with constrained resources, which may include limited CPU power, memory, storage, and user interface capabilities. These constraints affect both design and security: patching may be harder, logging may be minimal, and security features must be carefully engineered to fit the platform's limitations.
Option C best matches this characterization by describing a small form factor and limited processing power, which are typical attributes of many embedded devices. While not every embedded system is "small," the key idea is that it is purpose-built, resource-constrained, and tightly integrated into a larger product.
The other options describe different concepts. A secure underground facility relates to physical site security, not embedded computing. Being hard to remove is about physical installation or tamper resistance, which can apply to many systems but is not what defines "embedded." Storing cryptographic keys in a tamper-resistant external device describes a hardware security module or secure element use case, not the general definition of an embedded system.
質問 # 67
Which statement is true about a data warehouse?
正解：B
解説：
A data warehouse is designed primarily to support analytics, reporting, and decision-making rather than day-to-day transaction processing. Operational systems are optimized for fast inserts/updates and real-time business operations such as order entry, billing, or customer service workflows. In contrast, a warehouse consolidates data-often from multiple sources-into structures optimized for querying, trending, and historical analysis. From a cybersecurity and governance perspective, this distinction matters because warehouses frequently contain large volumes of aggregated, historical, and sometimes sensitive information, which can increase impact if confidentiality is breached. As a result, controls like strong access governance, role-based access, least privilege, segregation of duties, encryption, and audit logging are emphasized for warehouses to reduce insider misuse and limit exposure.
Option B is false because warehouses often use different structures (for example, dimensional models) than production systems, specifically to improve analytical performance and usability. Option C can be true in some architectures, but it is not universally required; organizations may operate multiple warehouses, data marts, or lakehouse patterns, and not all operational data is appropriate to centralize due to privacy, cost, and regulatory constraints. Option D is incorrect because cleansing is commonly performed in dedicated integration pipelines and staging layers rather than changing operational systems to "pre-clean" data. Therefore, A is the best verified statement.
