In cybersecurity risk management,impactrefers to theseverity of adverse consequencesif a threat event occurs and successfully affects information or systems. It is the “so what” of a risk scenario: how much damage the organization, its customers, or other stakeholders could experience when confidentiality, integrity, or availability is compromised. Impact commonly includes multiple dimensions such as operational disruption, loss of critical services, harm to customers, legal or regulatory exposure, reputational damage, and direct and indirect financial loss. Because these consequences can extend beyond money, impact is broader than just costs and also includes mission failure, safety implications, loss of competitive advantage, and degradation of trust.

Option D captures this correctly by describing impact as the magnitude of harm expected from unauthorized use of information. Option C describes likelihood, not impact, because it focuses on probability over time. Option B is only one component of impact, since financial cost is important but does not fully represent business, legal, and operational consequences. Option A is also a possible consequence but is narrower than the full impact concept. Cybersecurity risk scoring typically combines likelihood and impact to prioritize treatment, ensuring high-impact scenarios receive attention even when probabilities vary.

Whitelisting, often called an “allow list,” is a security approach where access is granted only toexplicitly approvedidentities, services, applications, IP addresses, domains, or network flows. In network security, this means the default stance is “deny by default,” and only pre-authorized entities are allowed to communicate or use specific resources. Option C matches this definition because it describes the core idea: explicitly permitting known, approved subjects (people, groups, service accounts, systems) to access a defined privilege or service.

Cybersecurity documents emphasize whitelisting as a strong risk-reduction technique because it constrains the attack surface. Instead of trying to block every bad thing (which is difficult due to evolving threats), whitelisting focuses on allowing only what is required for business operations. Examples include firewall rules that only permit specific source IPs to reach an admin interface, network segmentation policies that allow only required ports between zones, and application whitelisting that permits only approved executables to run. When implemented correctly, it reduces lateral movement opportunities, limits command-and-control traffic, and prevents unauthorized tools from executing.

Whitelisting is different from segmentation (option A), which is about isolating zones based on security needs, and different from blacklisting (option B), which blocks known-bad items. It is also not malware scanning (option D), which detects malicious code after it appears. Whitelisting aligns with least privilege and zero trust principles by tightly controlling what is allowed.

Anexternal auditis an independent evaluation performed by a party outside the organization to determine whether security-related activities, controls, and evidence meet defined requirements. Those requirements are typically drawn from laws and regulations, contractual obligations, and recognized standards or control frameworks. The defining characteristics areindependenceandattestation: the auditor is not part of the operational team being assessed and provides an objective conclusion about compliance or control effectiveness.

Unlike a vulnerability-focused review (often called a security assessment or technical audit) that primarily seeks weaknesses to remediate, an external audit emphasizes whether controls aredesigned appropriately, implemented consistently, and operating effectivelyover time. External auditors usually test governance processes, risk management practices, policies, access control procedures, change management, logging and monitoring, incident response readiness, and evidence of periodic reviews. They also validate documentation and sampling records to confirm that what is written is actually performed.

Option B describes an internal assurance activity, such as self-assessment or internal audit preparation, where the security team checks its own implementation. Option C is closer to a financial or procurement review and is not the typical definition of an external security audit. Therefore, the best answer is the one that clearly captures anindependent partyreviewing security activitiesto ensure compliancewith established criteria

Cybersecurity regulations most commonly focus on the protection ofpersonal data, because misuse or exposure can directly harm individuals through identity theft, fraud, discrimination, or loss of privacy. Privacy and data-protection laws typically require organizations to implement appropriate safeguards to protect personal information across its lifecycle, including collection, storage, processing, sharing, and disposal. In cybersecurity governance documentation, this obligation is often expressed through requirements to maintain confidentiality and integrity of personal data, limit access based on business need, and ensure accountability through logging, monitoring, and audits.

Demonstrating protection of personal data generally includes having a documented data classification scheme, clearly defined lawful purposes for processing, retention limits, and secure handling procedures. Technical controls commonly expected include strong authentication, least privilege and role-based access control, encryption for data at rest and in transit, secure key management, endpoint and server hardening, vulnerability management, and continuous monitoring for suspicious activity. Operational capabilities such as incident response, breach detection, and timely notification processes are also emphasized because regulators expect organizations to manage and report material data exposures appropriately.

While protecting applications, intellectual property, and ensuring continuity are important security objectives, they are not the primary focus of many cybersecurity regulations in the same consistent way aspersonal data protection. Therefore, the best answer is personal data of customers and employees.

Directories are commonly organized in a hierarchical structure, where each directory can contain sub-directories and files. In this hierarchy, the directory that contains another directory is referred to as theparent, and the contained sub-directory is referred to as thechild. This parent–child relationship is foundational to how file systems and many directory services represent and manage objects, including how paths are constructed and how inheritance can apply.

From a cybersecurity perspective, understanding parent and child relationships matters because access control and administration often follow the hierarchy. For example, permissions applied at a parent folder may be inherited by child folders unless inheritance is explicitly broken or overridden. This can simplify administration by allowing consistent access patterns, but it also introduces risk: overly permissive settings at a parent level can unintentionally grant broad access to many child locations, increasing the chance of unauthorized data exposure. Security documents therefore emphasize careful design of directory structures, least privilege at higher levels of the hierarchy, and regular permission reviews to detect privilege creep and misconfigurations.

The other options do not describe this standard hierarchy terminology. “Primary and Secondary” is more commonly used for redundancy or replication roles, not directory relationships. “Multi-factor Tokens” relates to authentication factors. “Embedded Layers” is not a st

Separation of duties is a foundational access-control and governance principle designed to reduce the likelihood of misuse, fraud, and significant mistakes by ensuring thatno single individual can complete a critical process end-to-end without independent oversight. Cybersecurity and audit frameworks describe this as splitting high-risk activities into distinct roles so that one person’s actions are checked or complemented by another person’s authority. This limits both intentional abuse, such as unauthorized payments or data manipulation, and unintentional errors, such as misconfigurations or accidental deletion of important records.

In practice, separation of duties is implemented by defining roles and permissions so that incompatible functions are not assigned to the same account. Common examples include separating the ability to create a vendor from the ability to approve payments, separating software development from production deployment, and separating system administration from security monitoring or audit log management. This is reinforced through role-based access control, approval workflows, privileged access management, and periodic access reviews that detect conflicting entitlements and privilege creep.

The value of separation of duties is risk reduction through accountability and control. When actions require multiple parties or independent review, it becomes harder for a single compromised account or malicious insider to cause large harm without detection. It also improves reliability by introducing checkpoints that catch mistakes earlier. Therefore, the correct purpose is to prevent fraud and error.

Personal information is classified primarily based on the harm that could result fromunauthorized disclosure, which maps directly to theconfidentialityobjective. Cybersecurity and privacy governance frameworks treat personal data as sensitive because exposure can lead to identity theft, fraud, discrimination, personal safety risks, and loss of privacy. Organizations also face regulatory penalties, contractual consequences, and reputational damage when personal data is disclosed without authorization. For this reason, when determining classification, the first and most influential question is typically: “What is the impact if this data becomes known to someone who should not have it?” That impact assessment drives the required protection level and handling rules.

Confidentiality-focused controls then follow from the classification decision, including least privilege and role-based access, strong authentication, encryption at rest and in transit, secure key management, data loss prevention where appropriate, logging and monitoring of access to sensitive records, and strict sharing/transfer procedures.

Integrity and availability matter for personal information, but they are usually secondary in classification decisions. Integrity affects trustworthiness and correctness (for example, incorrect medical or payroll data), and availability affects the ability to access records when needed. However, the defining sensitivity of personal information is that it must not be disclosed improperly. “Accessibility” is not a core security objective used in standard classification models; it is an operational usability concept that is managed through access design after sensitivity is established.

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 thePrivacy Ruleand theSecurity 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.

Cloud service models are commonly described as stacked layers of responsibility.Software as a Servicedelivers a complete application to the customer, while the provider manages the underlying platform and infrastructure.Platform as a Servicesits one level below SaaS: it provides the managed platform needed to build, deploy, and run applications without the customer having to manage the underlying servers and most core system software.

A defining feature of PaaS is that the provider supplies and manages key platform components such as theoperating system, runtime environment, middleware, web/application servers, and often supporting services like managed databases, messaging, scaling, and patching of the platform layer. The customer typically remains responsible for their application code, configuration, identities and access in the application, data classification and protection choices, and secure development practices. This shared responsibility model is central in cybersecurity guidance because it determines which security controls the provider enforces by default and which controls the customer must implement.

Given the answer options,Operating Systemis the best match because it is a core part of the platform layer that PaaS customers generally do not manage directly. Load balancers and storage can be consumed in multiple models, including IaaS and PaaS, and subscriptions describe a billing approach, not the technical service layer. Therefore, option D correctly reflects what PaaS provides compared to SaaS.

Privileged account management refers to the governance and operational controls used to administer accounts that haveelevated permissionsbeyond standard user access. Privileged accounts can change system configurations, create or modify users, access sensitive datasets, disable security tools, and administer core infrastructure such as servers, databases, directories, network devices, and cloud consoles. Because misuse of privileged access can quickly lead to large-scale compromise, cybersecurity frameworks treat privileged access as a high-risk area requiring stronger safeguards than normal accounts.

The definition in option A is correct because it captures the core purpose of privileged account management:establishing and maintaining access rights and controlsspecifically for roles that must perform administrative or support functions. In practice, this includes ensuring privileges are granted only when justified, scoped to the minimum necessary, and reviewed regularly. It also includes controls such as separation of duties, approval workflows, time-bound elevation, credential vaulting, rotation of privileged passwords and keys, multifactor authentication, and detailed logging of privileged sessions for monitoring and audit.

Option B is too broad because privileged account management is a specialized subset of identity and access management focused on elevated access. Option C is incorrect because privilege is defined by permissions, not job title. Option D describes an authentication concept, not the full management lifecycle of privileged access.
