Q341. What is digital forensics?
- The systematic examination of digital evidence to determine what occurred
2. A method for increasing network speed
3. A process for deleting malicious files only
4. A user account management system
Correct Answer: 1
Explanation:
Digital forensics is the systematic process of collecting, preserving, examining, and interpreting digital evidence. Investigators may examine computers, mobile devices, networks, cloud services, applications, logs, and other sources to determine what happened during a security incident. Forensic analysis can help establish timelines, identify attacker techniques, determine affected systems, and support root cause analysis. Investigators should use repeatable methods and document their procedures carefully. Evidence integrity is important because conclusions should be based on reliable information. Digital forensics is particularly useful when security teams need to reconstruct complex incidents or determine whether sensitive data or systems were compromised.
Q342. What is incident eradication?
- Removing malware, attacker access, persistence mechanisms, and other causes of compromise
2. Limiting the initial spread only
3. Creating new security alerts
4. Increasing network connectivity
Correct Answer: 1
Explanation:
Incident eradication focuses on removing the underlying malicious components and attacker access identified during an incident. This may include deleting malware, removing persistence mechanisms, disabling compromised accounts, patching exploited vulnerabilities, changing credentials, and correcting insecure configurations. Eradication should be based on the results of the investigation and should address the full scope of the compromise. Simply removing one malicious file may not be sufficient if an attacker has established additional access mechanisms. After eradication, systems should be validated and monitored to confirm that malicious activity has stopped. Effective eradication reduces the likelihood that the attacker can regain access after recovery.
Q343. What is incident recovery?
- Restoring affected systems and operations to a secure and functioning state
2. Creating new vulnerabilities
3. Deleting all security logs
4. Disabling monitoring permanently
Correct Answer: 1
Explanation:
Incident recovery restores affected systems, applications, and business operations after the threat has been contained and eradicated. Recovery may involve restoring clean backups, rebuilding systems, validating configurations, resetting credentials, testing applications, and gradually returning services to normal operation. Security validation is important because recovery should not reintroduce the original vulnerability or leave attacker access in place. Monitoring should continue after systems return to production so that unusual activity can be detected quickly. Recovery should also consider business continuity requirements and communication with system owners. Proper recovery helps organizations resume operations while maintaining an acceptable security posture.
Q344. What is vulnerability prioritization?
- Ranking vulnerabilities according to risk, exploitability, asset importance, and other factors
2. Treating every vulnerability as equally urgent
3. Deleting vulnerability records
4. Disabling vulnerability scanning
Correct Answer: 1
Explanation:
Vulnerability prioritization helps organizations determine which security weaknesses should be addressed first. A vulnerability’s severity alone may not provide enough information to make this decision. Security teams may also consider whether exploitation is occurring, whether a public exploit exists, how exposed the affected system is, the importance of the asset, available compensating controls, and the potential business impact. A critical vulnerability on an internet-facing system may require immediate attention, while a similar vulnerability on an isolated noncritical system may have a lower priority. Risk-based prioritization allows limited remediation resources to be directed toward weaknesses that present the greatest practical risk.
Q345. What is attack surface management?
- Identifying and monitoring assets and exposures that attackers could potentially target
2. Removing all internet-facing systems
3. Disabling vulnerability scanning
4. Increasing network traffic
Correct Answer: 1
Explanation:
Attack surface management focuses on identifying the systems, applications, services, cloud resources, and other assets that may be exposed to attackers. Organizations can have assets that are unknown, misconfigured, outdated, or unintentionally accessible from the internet. Attack surface management helps security teams maintain visibility and identify exposures that require attention. It can support vulnerability management, configuration reviews, asset inventory, and risk assessment. Continuous monitoring is important because environments change frequently as systems are deployed, removed, or modified. Reducing unknown or unnecessary exposure can make it more difficult for attackers to discover and exploit weaknesses in an organization’s environment.
Q346. What is an attack vector?
- A method or path an attacker uses to gain unauthorized access or cause harm
2. A legitimate backup procedure
3. A network performance measurement
4. A software licensing model
Correct Answer: 1
Explanation:
An attack vector is a method or pathway that an attacker can use to compromise a system, account, network, or other resource. Examples include phishing, stolen credentials, vulnerable internet-facing applications, malicious files, insecure configurations, and compromised third-party services. Understanding attack vectors helps security teams identify where defenses are needed and how attackers might enter an environment. Organizations can reduce exposure by implementing strong authentication, patching vulnerabilities, filtering malicious content, limiting access, and monitoring suspicious activity. Attack vectors can change over time as attackers discover new weaknesses and technologies evolve, so security teams should regularly reassess their environment and update defenses accordingly.
Q347. What is attack surface reduction?
- Reducing unnecessary systems, services, access paths, and exposures that attackers could exploit
2. Increasing the number of exposed services
3. Removing all security controls
4. Disabling vulnerability management
Correct Answer: 1
Explanation:
Attack surface reduction aims to minimize the number of opportunities available to attackers. Organizations can reduce their attack surface by disabling unnecessary services, removing unused accounts, restricting administrative access, closing unnecessary network ports, removing outdated software, reducing internet exposure, and applying secure configurations. The goal is not to eliminate every possible entry point because business systems still need to provide required functionality. Instead, organizations should identify unnecessary exposure and reduce it while preserving legitimate operations. Attack surface reduction works particularly well when combined with asset inventory, vulnerability management, least privilege, network segmentation, and continuous monitoring.
Q348. What is security risk assessment?
- Identifying, analyzing, and prioritizing risks to organizational resources and operations
2. Deleting all identified risks
3. Disabling security monitoring
4. Increasing user privileges
Correct Answer: 1
Explanation:
Security risk assessment evaluates potential threats and weaknesses and determines how they could affect organizational assets and operations. An assessment may consider the likelihood of a threat occurring, the potential impact, existing security controls, and remaining risk. The results help organizations prioritize security improvements and make informed decisions about where resources should be invested. Risk assessment should consider both technical and business factors because a vulnerability on a critical business system may present greater risk than the same vulnerability on a low-value asset. Assessments should be reviewed periodically because systems, threats, vulnerabilities, and business requirements change over time.
Q349. What is risk treatment?
- Selecting actions to reduce, accept, transfer, or otherwise manage identified security risks
2. Deleting risk assessments
3. Ignoring all security weaknesses
4. Disabling security policies
Correct Answer: 1
Explanation:
Risk treatment determines what an organization should do about an identified security risk. Common approaches include reducing the risk through additional controls, accepting it when it falls within approved tolerance, transferring aspects of the risk through appropriate arrangements, or avoiding the activity creating the risk. The appropriate approach depends on factors such as likelihood, impact, cost, business requirements, and risk tolerance. Risk treatment should be documented so that decision-makers understand what actions are planned and who is responsible. Security teams should also monitor treated risks because circumstances can change. Effective risk treatment ensures that security decisions are aligned with organizational priorities and acceptable levels of exposure.
Q350. What is continuous security improvement?
- Regularly improving security controls, processes, detections, and response capabilities based on evidence and lessons learned
2. Keeping security controls unchanged permanently
3. Removing all monitoring systems
4. Ignoring lessons from incidents
Correct Answer: 1
Explanation:
Continuous security improvement means regularly evaluating and strengthening security capabilities based on incidents, threat intelligence, testing, metrics, vulnerabilities, operational experience, and changes in the environment. Security cannot be treated as a one-time implementation because attackers, technologies, and business requirements constantly evolve. Organizations can improve by tuning detections, updating playbooks, improving logging, strengthening access controls, addressing vulnerabilities, testing response procedures, and reviewing previous incidents. Metrics can help identify areas where response times or detection coverage need improvement. A mature security operations program uses lessons learned to make measurable changes rather than repeating the same processes indefinitely. Continuous improvement helps organizations maintain effective defenses as the threat landscape changes.
Q351. What is the primary purpose of evaluating security control effectiveness?
- Determine whether security controls are achieving their intended security objectives
2. Remove all security controls from the environment
3. Increase the number of unrelated business applications
4. Disable security monitoring
Correct Answer: 1. Determine whether security controls are achieving their intended security objectives
Explanation: Security control effectiveness evaluation determines whether a control is actually reducing the risk it was designed to address. A control may exist and be configured correctly but still fail to provide adequate protection because of configuration errors, coverage gaps, outdated rules, or changes in the environment. Security teams can evaluate controls through testing, monitoring, metrics, audits, and simulated security events. The results help organizations identify weaknesses and improve their defensive capabilities. Effective evaluation should consider both preventive and detective controls and should verify that controls operate as expected under realistic conditions. Therefore, determining whether security controls achieve their intended objectives is the correct answer.
Q352. What does security control maturity describe?
- The level of development, consistency, and effectiveness of an organization’s security controls
2. The physical age of security hardware
3. The number of employees in a security team
4. The amount of network bandwidth available
Correct Answer: 1. The level of development, consistency, and effectiveness of an organization’s security controls
Explanation: Security control maturity describes how developed and consistently managed an organization’s security controls are. A mature control environment generally includes documented processes, defined ownership, regular testing, monitoring, measurable performance, and continuous improvement. Immature controls may depend heavily on manual activities, inconsistent configurations, or individual knowledge. Maturity does not simply mean that an organization owns advanced security products. Instead, it considers how effectively those controls are designed, implemented, operated, measured, and improved. Security operations teams use maturity assessments to identify gaps and establish improvement priorities. Therefore, the level of development, consistency, and effectiveness of security controls is the best answer.
Q353. What is the primary purpose of security governance?
- Establish direction, accountability, policies, and oversight for security activities
2. Replace all technical security controls
3. Increase the number of network connections
4. Eliminate security policies
Correct Answer: 1. Establish direction, accountability, policies, and oversight for security activities
Explanation: Security governance provides the organizational structure used to direct and oversee security activities. It defines responsibilities, establishes policies and standards, supports risk management, and ensures that security objectives align with business requirements. Good governance also establishes accountability and helps management understand whether security programs are operating effectively. Technical controls such as firewalls, endpoint protection, and monitoring tools are important, but governance determines how those controls should be managed and measured. Governance can also define approval processes, risk ownership, compliance expectations, and reporting requirements. Therefore, establishing direction, accountability, policies, and oversight for security activities is the correct answer.
Q354. What does risk appetite represent?
- The amount and type of risk an organization is generally willing to accept
2. Every risk that must immediately be eliminated
3. The number of security alerts generated each day
4. The number of vulnerabilities found during scanning
Correct Answer: 1. The amount and type of risk an organization is generally willing to accept
Explanation: Risk appetite represents the overall level and types of risk an organization is willing to accept while pursuing its objectives. It provides high-level guidance for security and business decisions. For example, an organization may have a low appetite for risks involving sensitive customer information while accepting a greater level of operational risk in certain controlled situations. Risk appetite helps management establish priorities and make consistent decisions about security investments and risk treatment. It is broader than a single vulnerability or security incident. Security teams should align risk decisions with organizational risk appetite rather than treating every risk identically. Therefore, the amount and type of risk an organization is generally willing to accept is correct.
Q355. What is risk tolerance?
- The acceptable level of variation or exposure around a specific risk objective
2. A requirement to eliminate every possible risk
3. The number of security analysts assigned to an incident
4. The total number of security tools deployed
Correct Answer: 1. The acceptable level of variation or exposure around a specific risk objective
Explanation: Risk tolerance defines how much deviation from an organization’s risk objectives can be accepted in a particular situation. It is generally more specific than risk appetite. For example, an organization may have a low overall appetite for security risk and establish a specific tolerance for the time that critical vulnerabilities can remain unresolved. Risk tolerance provides practical boundaries for decision-making and helps teams determine when escalation or corrective action is required. Security operations can use these thresholds to prioritize remediation, monitoring, and incident response. Therefore, the acceptable level of variation or exposure around a specific risk objective is the correct answer.
Q356. What is the purpose of a security risk register?
- Record identified risks, their characteristics, owners, treatments, and status
2. Store only employee passwords
3. Replace network monitoring systems
4. Record only completed security incidents
Correct Answer: 1. Record identified risks, their characteristics, owners, treatments, and status
Explanation: A security risk register provides a structured record of identified risks and the information needed to manage them. Typical entries may include the risk description, affected assets, likelihood, impact, risk rating, responsible owner, treatment plan, current status, and review date. The register helps security and business teams maintain visibility into important risks and track whether planned treatments have been completed. It can also support management reporting and prioritization. A risk register is not simply an incident log or password repository. Its purpose is broader risk management. Therefore, recording identified risks, their characteristics, owners, treatments, and status is the correct answer.
Q357. What is residual risk?
- The risk that remains after security controls and risk treatments are applied
2. The risk before any controls are implemented
3. A risk that has never been identified
4. A risk created only by network hardware
Correct Answer: 1. The risk that remains after security controls and risk treatments are applied
Explanation: Residual risk is the remaining level of risk after an organization has implemented security controls or other treatment measures. Risk cannot always be completely eliminated because technical limitations, business requirements, uncertainty, and changing threats can leave some exposure. Organizations therefore assess residual risk to determine whether the remaining exposure is acceptable. If it is not acceptable, additional controls or treatment may be required. Residual risk should be documented and monitored because changes in systems, threats, or controls can increase it over time. Therefore, the risk remaining after controls and treatments are applied is the correct answer.
Q358. What is inherent risk?
- The level of risk that exists before security controls or treatments are considered
2. The risk remaining after all controls are implemented
3. A risk that has already been transferred
4. A risk that applies only to security employees
Correct Answer: 1. The level of risk that exists before security controls or treatments are considered
Explanation: Inherent risk represents the level of exposure associated with an activity, system, process, or asset before considering mitigating security controls. It provides a baseline for understanding how risky a situation would be without protective measures. For example, an internet-facing service may have significant inherent risk because it is exposed to external attackers. Firewalls, authentication, monitoring, and vulnerability management may reduce that exposure, producing a lower residual risk. Comparing inherent and residual risk helps organizations evaluate whether their controls are reducing exposure effectively. Therefore, the level of risk before controls or treatments are considered is the correct answer.
Q359. What is the primary purpose of security policy enforcement?
- Ensure that established security requirements and rules are consistently followed
2. Allow users to ignore security requirements
3. Disable access controls throughout the organization
4. Remove security standards from business processes
Correct Answer: 1. Ensure that established security requirements and rules are consistently followed
Explanation: Security policy enforcement ensures that employees, systems, and processes follow established security requirements. Policies may define password standards, access requirements, acceptable use, data handling, remote access, and other security expectations. Enforcement can involve technical controls, monitoring, audits, automated checks, and management processes. Without enforcement, policies may exist only as documentation and provide little practical protection. Effective enforcement should also include appropriate exceptions and approval procedures when legitimate business needs require deviations. Security teams can use monitoring and compliance measurements to identify violations and improve adherence. Therefore, ensuring established security requirements and rules are consistently followed is the correct answer.
Q360. What is security control monitoring?
- Continuously or periodically observing controls to verify their operation and effectiveness
2. Removing controls after deployment
3. Monitoring only employee attendance
4. Disabling security alerts
Correct Answer: 1. Continuously or periodically observing controls to verify their operation and effectiveness
Explanation: Security control monitoring involves observing security controls to determine whether they remain properly configured, operational, and effective. Controls can degrade because of configuration changes, software updates, infrastructure changes, expired certificates, disabled rules, or evolving threats. Monitoring can identify these problems before they create significant security gaps. Examples include checking firewall policies, endpoint protection status, logging coverage, access-control configurations, and detection rules. Monitoring can be continuous or periodic depending on the control and risk level. The objective is not merely to confirm that a control exists but to verify that it continues to provide the expected protection. Therefore, observing controls to verify their operation and effectiveness is correct.
