In cybersecurity risk management,risk treatmentis the set of actions used to reduce risk to an acceptable level. The most common tool used to directly treat or mitigate cyber risk is acontrolbecause controls are the specific safeguards that prevent, detect, or correct adverse events. Cybersecurity frameworks describe controls as measures implemented to reduce either thelikelihoodof a threat event occurring or theimpactif it does occur. Controls can be technical (such as multifactor authentication, encryption, endpoint protection, network segmentation, logging and monitoring), administrative (policies, standards, training, access approvals, change management), or physical (badges, locks, facility protections). Regardless of type, controls are the direct mechanism used to mitigate identified risks.

Anexit strategyis typically a vendor or outsourcing risk management concept focused on how to transition away from a provider or system; it supports resilience but is not the primary tool for directly mitigating a specific cyber risk.Standardsguide consistency by defining required practices and configurations, but the standard itself is not the mitigation—controls implemented to meet the standard are. Abusiness continuity plansupports availability and recovery after disruption, which is important, but it primarily addresses continuity and recovery rather than directly reducing the underlying cybersecurity risk in normal operations. Therefore, the best answer is the one that represents the direct implementation of safeguards:controls.

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

Integritymeans information and systems remain accurate, complete, and protected from unauthorized or improper modification. ThePrinciple of Least Privilegeis a direct integrity protection control because it limits who can change data and what changes they are allowed to make. Under least privilege, users, applications, and service accounts receive only the minimum permissions needed to perform approved tasks, and nothing more. This reduces the chance that an attacker using a compromised account can alter records, manipulate transactions, or change configurations, and it also reduces accidental changes by well-meaning users who do not need write or administrative rights.

Least privilege is commonly enforced through role-based access control, separation of duties, restricted administrative roles, just-in-time elevation for privileged tasks, and periodic access reviews to remove excess permissions. These practices are emphasized in cybersecurity frameworks because integrity failures often occur when excessive access allows unauthorized edits to sensitive data, logs, security settings, or application code.

The other options relate to security but are less directly tied to integrity as the primary objective.Biometric verificationis an authentication method that helps confirm identity; it supports access control broadly, but it does not by itself limit modification capability once access is granted.Anti-malicious code detectionhelps prevent malware that could corrupt data, but it is primarily a detection/prevention tool rather than the foundational control for authorized modification.Backups and redundancyprimarily support availability and recovery after corruption, not the prevention of unauthorized changes.
