質問 # 59
Analyst B has discovered unauthorized access to data. What has she discovered?
正解：B
解説：
Unauthorized access to data is the defining condition of a data breach. In standard cybersecurity terminology, a breach occurs when confidentiality is compromised-meaning data is accessed, acquired, viewed, or exfiltrated by an entity that is not authorized to do so. This is distinct from a "threat," which is only the potential for harm, and distinct from a "hacker," which describes an actor rather than the security outcome. A breach can result from external attackers, malicious insiders, credential theft, misconfigurations, unpatched vulnerabilities, or poor access controls. Cybersecurity guidance typically frames breaches as realized security incidents with measurable impact: exposure of regulated data, loss of intellectual property, fraud risk, reputational harm, and legal/regulatory consequences. Once unauthorized access is confirmed, incident response procedures generally require containment (limit further access), preservation of evidence (logs, system images where appropriate), eradication (remove persistence), and recovery (restore secure operations). Organizations also assess scope-what data types were accessed, how many records, which systems, and the dwell time-and then determine notification obligations where laws or contracts apply. In short, the discovery describes an actual compromise of data confidentiality, which is precisely a breach.

The hash function supports data in transit by ensuring:
正解：A
解説：
A cryptographic hash function supports data in transit primarily by providing integrity assurance. When a sender computes a hash (digest) of a message and the receiver recomputes the hash after receipt, the two digests should match if the message arrived unchanged. If the message is altered in any way while traveling across the network-whether by an attacker, a faulty intermediary device, or transmission errors-the recomputed digest will differ from the original. This difference is the key signal that the message was modified in transit, which is what option B expresses. In practical secure-transport designs, hashes are typically combined with a secret key or digital signature so an attacker cannot simply modify the message and generate a new valid digest. Examples include HMAC for message authentication and digital signatures that hash the content and then sign the hash with a private key. These mechanisms provide integrity and, when keyed or signed, also provide authentication and non-repudiation properties.
Option A is more specifically about authentication of origin, which requires a keyed construction such as HMAC or a signature scheme; a plain hash alone cannot prove who sent the message. Option C is incorrect because keys are not "converted" from public to private. Option D relates to confidentiality, which is provided by encryption, not hashing. Therefore, the best answer is B because hashing enables detection of message modification during transit.
質問 # 61
NIST 800-30 defines cyber risk as a function of the likelihood of a given threat-source exercising a potential vulnerability, and:
正解：B
解説：
NIST SP 800-30 describes risk using a classic risk model: risk is a function of likelihood and impact. In this model, a threat-source may exploit a vulnerability, producing a threat event that results in adverse consequences. The likelihood component reflects how probable it is that a threat event will occur and successfully cause harm, considering factors such as threat capability and intent (or in non-adversarial cases, the frequency of hazards), the existence and severity of vulnerabilities, exposure, and the strength of current safeguards. However, likelihood alone does not define risk; a highly likely event that causes minimal harm may be less important than a less likely event that causes severe harm.
The second required component is the impact-the magnitude of harm to the organization if the adverse event occurs. Impact is commonly evaluated across mission and business outcomes, including financial loss, operational disruption, legal or regulatory consequences, reputational damage, and loss of confidentiality, integrity, or availability. This is why option D is correct: NIST's definition explicitly ties the risk expression to the resulting impact on the organization.
The other options may influence likelihood assessment or control selection, but they are not the missing definitional element. Detection probability and control assurance relate to monitoring and governance; predisposing conditions can shape likelihood. None replace the
質問 # 62
Which of the following should be addressed in the organization's risk management strategy?
正解：B
解説：
An organization's risk management strategy is a governance-level artifact that sets direction for how risk is managed across the enterprise. A core requirement in cybersecurity governance frameworks is clear accountability, including executive ownership for risk decisions that affect the whole organization. Assigning an executive responsible for risk management establishes authority to set risk appetite and tolerance, coordinate risk activities across business units, resolve conflicts between competing priorities, and ensure risk decisions are made consistently rather than in isolated silos. This executive role also supports oversight of risk reporting to senior leadership, ensures resources are allocated to address material risks, and drives integration between cybersecurity, privacy, compliance, and operational resilience programs. Without an accountable executive function, risk management often becomes fragmented, with inconsistent scoring, uneven control implementation, and unclear decision rights for accepting or treating risk.
Option A can be part of a strategy, but the question asks what should be addressed, and the most critical foundational element is enterprise accountability and governance. Option B is too granular for a strategy; selecting controls for each IT asset belongs in security architecture, control baselines, and system-level risk assessments. Option C is typically handled in incident response and breach management plans and procedures, which are operational documents derived from strategy but not the strategy itself. Therefore, the best answer is the assignment of an executive responsible for risk management across the organization.
質問 # 63
Which of the following terms represents an accidental exploitation of a vulnerability?
正解：D
解説：
In cybersecurity risk terminology, an event is an observable occurrence that can affect systems, services, or data. An event may be benign, harmful, intentional, or accidental. When a vulnerability is exploited accidentally-for example, a user unintentionally triggers a software flaw, a misconfiguration causes unintended exposure, or a system process mishandles input and causes data corruption-the occurrence is best categorized as an event. Cybersecurity documentation often distinguishes between the possibility of harm and the actual occurrence of a harmful condition. A threat is the potential for an unwanted incident, such as an actor or circumstance that could exploit a vulnerability. A threat does not require that exploitation actually happens; it describes risk potential. An agent is the entity that acts (such as a person, malware, or process) and may be malicious or non-malicious, but "agent" is not the term for the occurrence itself. A response refers to the actions taken after detection, such as containment, eradication, recovery, and lessons learned; it is part of incident handling, not the accidental exploitation.
Therefore, the term that represents the actual accidental exploitation occurrence is event, because it captures the real-world happening that may trigger alerts, investigations, and potentially incident response activities if impact is significant.
