CISA Exam Dumps - Isaca Certification Questions and Answers

The best source of information for an IS auditor to use as a baseline to assess the adequacy of an organization’s privacy policy is the local privacy standards and regulations. Privacy standards and regulations are legal requirements that specify how personal data should be collected, processed, stored, shared, and disposed of by organizations. By using local privacy standards and regulations as a baseline, the IS auditor can ensure that the organization’s privacy policy complies with the applicable laws and protects the rights and interests of data subjects. Historical privacy breaches and related root causes, globally accepted privacy best practices, and benchmark studies of similar organizations are useful sources of information for improving an organization’s privacy policy, but they are not as authoritative and relevant as local privacy standards and regulations. References: CISAReview Manual (Digital Version): Chapter 2 - Governance and Management of Information Technology

 The primary purpose of creating a simulated production environment with multiple vulnerable applications is to attract attackers in order to study their behavior. This is a technique known as honeypotting, which is a form of deception security that lures attackers into a fake system or network that mimics the real one, but is isolated and monitored1. Honeypotting can help security teams to learn about the attackers’ methods, tools, motives, and targets, and to collect valuable intelligence that can be used to improve the security posture of the organization1. Honeypotting can also help to divert the attackers’ attention from the real assets and to waste their time and resources2.

The other options are not the primary purpose of creating a simulated production environment with multiple vulnerable applications. To collect digital evidence of cyberattacks, security teams would need to use forensic tools and techniques that can preserve and analyze the data from the compromised systems or networks3. To provide training to security managers, security teams would need to use simulation tools and scenarios that can test and enhance their skills and knowledge in responding to cyber incidents4. To test the intrusion detection system (IDS), security teams would need to use penetration testing tools and methods that can evaluate the effectiveness and performance of the IDS in detecting and preventing malicious activities5.

The best control to mitigate attacks that redirect Internet traffic to an unauthorized website is to perform domain name system (DNS) server security hardening. DNS servers are responsible for resolving domain names into IP addresses, and they are often targeted by attackers who want to manipulate or spoof DNS records to redirect usersto malicious websites4. By applying security best practices to DNS servers, such as encrypting DNS traffic, implementing DNSSEC, restricting access and updating patches, the organization can reduce the risk of DNS hijacking attacks. A network-based firewall, user security awareness training and a strong password policy are also important controls, but they are not as effective as DNS server security hardening in preventing this specific type of attack. References:

 Adequate action taken for noncompliance with the service level agreement (SLA) provides the best evidence that outsourced provider services are being properly managed. This shows that the organization is monitoring the performance of the provider and enforcing the terms of the SLA.

The other options are not as convincing as evidence of proper management. Option A, the SLA includes penalties for non-performance, is a good practice but does not guarantee that the penalties are actually applied or that the performance is satisfactory. Option C, the vendor provides historical data to demonstrate its performance, is not reliable because the data may be biased or inaccurate. Option D, internal performance standards align with corporate strategy, is irrelevant to the question of outsourced provider management.

The best answer is A. Identifying the risk scoring criteria.

A risk register becomes useful only when identified risks can be assessed consistently and prioritized. ISACA guidance describes the risk register as a record of identified risks including their determined risk levels, and explains that risk level is determined based on methodology involving threats, vulnerabilities, impact, probabilities, and asset value. That means the criteria for scoring must be established so risks can be evaluated and ranked in a consistent way.

Option B is important after risks are identified and assessed, because ownership drives accountability. Option C follows prioritization and ownership. Option D may help identify risks but is not the key action in populating the register itself. The register’s value depends first on a sound scoring basis that turns a list of concerns into prioritized risk information.

 The chain of custody has not been documented is a finding that should be of greatest concern for an IS auditor reviewing a forensic analysis process of an organization that has suffered a cyber attack. The chain of custody is a record of who handled, accessed, or modified the evidence during a forensic investigation. Documenting the chain of custody is essential to preserve the integrity, authenticity, and admissibility of the evidence in a court of law. The other options are less concerning findings that may not affect the validity or reliability of the forensic analysis process. References:

CISA Review Questions, Answers andExplanations Database, Question ID 220

The best situation that justifies the use of a smaller sample size when testing the accuracy of transaction data is B. It is expected that the population is error-free. The sample size is the number of items selected from the population for testing. The sample size depends on various factors, such as the level of confidence, the tolerable error rate, the expected error rate, and the variability of the population. A smaller sample size means that fewer items are tested, which reduces the cost and time of testing, but also increases the sampling risk (the risk that the sample is not representative of the population).

One of the factors that affects the sample size is the expected error rate, which is the auditor’s best estimate of the proportion of errors in the population before testing. A higher expected error rate means that more errors are likely to be found in the population, which requires a larger sample size to provide sufficient evidence for the auditor’s conclusion. A lower expected error rate means that fewer errors are likely to be found in the population, which allows a smaller sample size to provide sufficient evidence for the auditor’s conclusion. Therefore, if it is expected that the population is error-free (i.e., the expected error rate is zero or very low), a smaller sample size can be justified.

The other situations do not justify the use of a smaller sample size when testing the accuracy of transaction data. A. The IS audit staff has a high level of experience. The IS audit staff’s level of experience does not affect the sample size, but rather their ability to design and execute the sampling procedures and evaluate the results. The IS audit staff’s level of experience may affect their judgment in selecting and applying sampling methods, but it does not change the statistical or mathematical principles that determine the sample size. B. Proper segregation of duties is in place. Proper segregation of duties is an internal control that helps prevent or detect errors or fraud in transaction processing, but it does not affect the sample size. The sample size is based on the characteristics of the population and the objectives of testing, not on the controls in place. Proper segregation of duties may reduce the likelihood or impact of errors or fraud in transaction processing, but it does not eliminate them completely. Therefore, proper segregation of duties does not justify a smaller sample size when testing the accuracy of transaction data. C. The data can be directly changed by users. The data’s ability to be directly changed by users does not justify a smaller sample size, but rather a larger one. The data’s ability to be directly changed by users increases the risk of errors or fraud in transaction processing, which requires a larger sample size to provide sufficient evidence for the auditor’s conclusion. The data’s ability to be directly changed by users also increases the variability of the population, which affects the sample size.

Service accountsare used by applications or systems to perform automated tasks and shouldnot be allowed for interactive login, as they present security risks if compromised.

Service Accounts (Correct Answer – D)

Used for running background tasks (e.g., database services, scheduled jobs).

Should have minimal permissions and be denied interactive logins.

Example:A compromised service account with interactive login could allow attackers to gain system access.

Local Accounts (Incorrect – A)

Local administrator accounts should be restricted but may still be required for some systems.

Administrator Accounts (Incorrect – B)

Should be restricted, but disabling them entirely could lock out system management.

Console Accounts (Incorrect – C)

Console access is sometimes needed for system recovery and troubleshooting.

The correct answer is B. Review the terms and provisions in the contract.

When auditing an outsourced application, the auditor should first understand the contractual responsibilities, service scope, control expectations, reporting requirements, audit rights, compliance obligations, and security commitments. ISACA guidance on outsourcing and third-party assurance emphasizes that contracts are foundational because they define what the service provider is obligated to do and what the customer is entitled to review.

Option A is not first because billing validation is secondary to understanding the service arrangement and obligations.

Option C is incorrect because implementing access rights is a management responsibility, not an audit procedure.

Option D is important, but the auditor must first know whether such reporting is required, how it is defined, and under what timelines, all of which are typically governed by the contract or related agreement.

Therefore, the correct answer is B, because contract review establishes the basis for all further audit work over the outsourced HR application.

References (Official ISACA):

ISACA Journal, Third Party Assurance — highlights the importance of understanding outsourced service arrangements and related assurance expectations.

ISACA Now Blog, The Challenging Task of Auditing Social Media — states that when a function is outsourced, the contract should be reviewed to ensure it specifies required activities and expectations.

Visualization technology is the use of software and hardware to create graphical representations of data, such as charts, graphs, maps, images, etc. Visualization technology can help users to understand, analyze, and communicate complex and large amounts of data in an intuitive and engaging way1.

One of the primary advantages of using visualization technology for corporate applications is that it can improve the utilization of resources, such as time, money, human capital, and physical assets. Some of the ways that visualization technology can achieve this are:

Visualization technology can help users to quickly and easily explore, filter, and interact with data, reducing the need for manual data processing and analysis1. This can save time and effort for both data producers and consumers, and allow them to focus on more value-added tasks.

Visualization technology can help users to discover patterns, trends, outliers, correlations, and causations in data that may otherwise be hidden or overlooked in traditional reports or tables1. This can enable users to make better and faster decisions based on data-driven insights, and optimize their strategies and actions accordingly.

Visualization technology can help users to communicate and share data more effectively and persuasively with different audiences, such as customers, partners,investors, regulators, etc1. This can enhance the reputation and credibility of the organization, and foster collaboration and innovation among stakeholders.

Visualization technology can help users to monitor and measure the performance and impact of their activities, products, services, or processes1. This can help users to identify problems or opportunities for improvement, and adjust their plans or actions accordingly.

Visualization technology can help users to create engaging and interactive experiences for their customers or end-users1. This can increase customer satisfaction and loyalty, and generate more revenue or value for the organization.

Therefore, using visualization technology for corporate applications can help organizations to better utilize their resources and achieve their goals.

The most important consideration when planning the next audit after many findings is to follow up on the status of all recommendations, as this will ensure that the audit findings are addressed in a timely and effective manner, and that the root causes of the issues are resolved12. Following up on the status of all recommendations will also help to assess the progress and performance of the IT department, and to identify any new or emerging risks or challenges34.

Segregation of duties is a fundamental concept in cybersecurity and information security. It refers to the practice of dividing critical tasks and responsibilities among different individuals or roles within an organization to reduce the risk of fraud, error, or unauthorized activities1. Segregation of duties is designed to prevent unilateral actions within an organization’s workflow, which can result in damaging events that would exceed the organization’s risk tolerance2.

There are different types of responses to risk associated with segregation of duties, depending on the level of risk and the cost-benefit analysis. Some of the common responses are:

Risk acceptance: This means acknowledging a risk and deciding to tolerate it without taking any corrective actions. This response is usually chosen when the risk is low or the cost of mitigation is too high3.

Risk mitigation: This means taking steps ahead of time to lessen the effects of a risk and make it less likely to happen. Some examples of mitigation strategies are making backup plans, setting up early warning systems, and staying away from high-risk areas or activities4.

Risk transference: This means shifting the negative impact of a risk and/or the responsibility for managing the risk response to a third party. Some examples of transference strategies are outsourcing, insurance, or contracts5.

Risk reduction: This means reducing the probability and/or severity of the risk below a threshold of acceptability. Some examples of reduction strategies are implementing controls, policies, or procedures to prevent or detect risks6.

Based on these definitions, the response to risk associated with segregation of duties that would incur the lowest initial cost is A. Risk acceptance. This is because risk acceptance does not require any additional resources or actions to address the risk. However, risk acceptance also implies that the organization is willing to bear the consequences of the risk if it occurs, which could be costly in the long run.

Therefore, the correct answer to your question is A. Risk acceptance.

IT application owners having sole responsibility for architecture approval (B) is a major concern because it indicates a lack of oversight and segregation of duties. EA decisions should be reviewed by a cross-functional governance body to ensure alignment with security, compliance, and business objectives.

Other options:

The CIO chairing the review board (A) may indicate centralized leadership but is not inherently a risk.

EA governing non-IT projects (C) may indicate scope expansion but is not a security risk.

Security requirements being reviewed (D) is a best practice and not a concern.

 The best option for ensuring confidentiality through the use of asymmetric encryption is to encrypt a message with the recipient’s public key (option A). This is because:

Asymmetric encryption, also known as public-key cryptography, is a type of encryption that uses a pair of keys to encrypt and decrypt data. The pair of keys includes a public key, which can be shared with anyone, and a private key, which is kept secret by the owner12.

In asymmetric encryption, the sender uses the recipient’s public key to encrypt the data. The recipient then uses their private key to decrypt the data. This approach allows for secure communication between two parties without the need for both parties to have the same secret key12.

Encrypting a message with the recipient’s public key ensures that only the recipient can decrypt it with their private key. This provides confidentiality, which means that the message is protected from unauthorized access or disclosure12.

Encrypting a message with the sender’s private key (option B) does not ensure confidentiality, but rather authentication, which means that the message can be verified as coming from the sender. This is because anyone can decrypt the message with the sender’s public key, but only the sender can encrypt it with their private key12.

Encrypting a message with the sender’s public key (option C) or the recipient’s private key (option D) does not make sense, as it would render the message unreadable by both parties. This is because neither party has the corresponding key to decrypt it12.

Therefore, the best option for ensuring confidentiality through the use of asymmetric encryption is to encrypt a message with the recipient’s public key (option A), as this ensures that only the recipient can decrypt it with their private key.

Capacity management must consider business changes to ensure IT resources can meet future demand. If changes to critical systems are omitted from planning, capacity forecasts will be inaccurate, leading to risks of downtime, bottlenecks, and unplanned outages. A six-month review (A) might be acceptable depending on system dynamics. Lack of administrator input (C) and reliance on service management (D) reduce planning quality but are less critical than missing major business drivers. COBIT DSS01 (Managed Operations) and APO02 (Managed Strategy) emphasize alignment between IT capacity and business requirements.

References (ISACA): COBIT® 2019, DSS01 Managed Operations; APO02 Managed Strategy.

Imaging the affected system is the best way to protect evidence in a forensic investigation, because it creates a bit-by-bit copy of the original data that can be analyzed without altering or compromising the original source. Imaging preserves the integrity and authenticity of the evidence and allows for verification and validation of the results34. Powering down or rebooting the affected system can cause data loss or corruption, while protecting the hardware does not prevent unauthorized access or tampering with the software or data. References: 3: CISA Review Manual (Digital Version), Chapter 6, Section 6.4.1 4: CISA Online Review Course, Module 6, Lesson 4

Reviewing the performance against service level agreements (SLAs) would best determine whether the service provider continues to meet the organization’s objectives, as SLAs define the expected level of service, quality, availability, and responsibilities of both parties. Assessment of the personnel training processes of the provider, adequacy of the service provider’s insurance, and periodic audits of controls by an independent auditor are important aspects of outsourcing, but they do not directly measure the performance of the service provider against the organization’s objectives. References: CISA Review Manual (Digital Version), Chapter 3, Section 3.5.2

A load balancer is a tool or application that distributes incoming network traffic among multiple servers in a server farm, so that no server is overwhelmed and the performance of the system is optimized1. A load balancer can help the agency to handle the large influx of traffic to a regional office by balancing the workload among the available servers and preventing service disruptions. A load balancer can also provide high availability and fault tolerance by rerouting traffic to online servers if a server becomes unavailable2.

A virtual firewall is a software-based firewall that protects a virtual network or environment from unauthorized access and malicious attacks. A virtualfirewall can enhance the security of the agency’s network, but it does not improve the performance of its servers.

A proxy server is an intermediary server that acts as a gateway between the client and the destination server, hiding the client’s IP address and providing caching and filtering functions. A proxy server can improve the security and privacy of the agency’s network, but it does not improve the performance of its servers.

A virtual private network (VPN) is a secure connection between two or more devices over a public network, such as the internet. A VPN can encrypt and protect the data transmitted over the network, but it does not improve the performance of the agency’s servers.

Internalquality assurance (QA) reviewsare conducted toensure conformancewith professionalaudit standards and methodology.

Option A (Correct):The primary purpose of QA reviews is toconfirm that the internal audit function adheres to industry standards, such asISACA’s IT audit frameworkand theInternational Standards for the Professional Practice of Internal Auditing (IPPF).

Option B (Incorrect):Whilegovernance and performance metricsare important,conformance to standardsis theprimary goalof QA reviews.

Option C (Incorrect):Risk management is part of audits, butQA reviews focus on adherence to methodologyrather than reducing audit risk.

Option D (Incorrect):Efficient resource usageis a goal butnot the main objectiveof an audit QA program.

 A system electronic log is the most useful source of information for an IS auditor to review all access attempts to a video-monitored and proximity card-controlled communications room. A system electronic log can provide accurate and detailed records of the date, time, card number, and status (success or failure) of each access attempt. A system electronic log can also be easily searched, filtered, and analyzed by the auditor to identify any unauthorized or suspicious access attempts.

A manual sign-in and sign-out log is not as reliable or useful as a system electronic log, because it depends on the honesty and compliance of the users. A manual log can be easily manipulated, forged, or omitted by the users or intruders. A manual log also does not capture the status of each access attempt, and it can be difficult to verify the identity of the users based on their signatures.

An alarm system with CCTV is not as useful as a system electronic log, because it only captures the events that trigger the alarm, such as unauthorized or forced entry. An alarm system with CCTV does not provide a complete record of all access attempts, and it can be affected by factors such as camera angle, lighting, and resolution. An alarm system with CCTV also requires more time and effort to review the video footage by the auditor.

A security incident log is not as useful as a system electronic log, because it only records the incidents that are reported by the users or detected by the security staff. A security incident log does not provide a comprehensive record of all access attempts, and it can be incomplete or inaccurate depending on the reporting and detection mechanisms. A security incident log also does not capture the details of each access attempt, such as the card number and status.

The greatest risk associated with having most users with administrator access to an externally facing system containing sensitive data is that users can make unauthorized changes to the system or the data, which could compromise the integrity, confidentiality, and availability of the system and the data. Users can export application logs, view sensitive data, and install open-licensed software are also risks, but they are not as severe as unauthorized changes. References: ISACA CISA Review Manual 27th Edition Chapter 4

The best audit evidence that a firewall is configured in compliance with the organization’s security policy is to review the rule base. The rule base is a set of rules that defines the criteria for allowing or denying network traffic through the firewall. By reviewing the rule base, the auditor can verify if the firewall configuration matches the security policy requirements and objectives. Analyzing how the configuration changes are performed, analyzing log files, and performing penetration testingare useful audit techniques, but they do not provide direct evidence of the firewall configuration compliance. References: CISA Review Manual (Digital Version)1, page 383.

 Computer performance is the measure of how well a computer system can execute tasks and applications within a given time frame. Computer performance can be affected by various factors, such as hardware specifications, software configuration, network conditions, and user behavior. To analyze computer performance, it is important to use statistical metrics that can quantify the capacity utilization of the system resources, such as CPU, memory, disk, and network. These metrics can help identify the bottlenecks, inefficiencies, and anomalies that may degrade the performance of the system. Examples of such metrics include CPU utilization, memory usage, disk throughput, network bandwidth, and response time.

The other options are not as useful as statistical metrics when analyzing computer performance. An operations report of user dissatisfaction with response time is a subjective measure that may not reflect the actual performance of the system. Tuning of system software to optimize resource usage is a corrective action that can improve performance, but it is not a method of analysis. A report of off-peak utilization and response time is a limited snapshot that may not capture the peak performance or the average performance of the system.

 The auditor’s primary concern when capacity management for a key system is being performed by IT with no input from the business would be an unanticipated increase in business’s capacity needs. This could result in performance degradation, service disruption or customer dissatisfaction if IT is not able to provide sufficient capacity to meet the business demand. Failure to maximize the use of equipment, cost of excessive data center storage capacity or impact to future business project funding are secondary concerns that relate to resource optimization or budget allocation, but not to service delivery or customer satisfaction. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 374

The first step when developing a DLP solution for a large organization is to conduct a data inventory and classification exercise. This step involves identifying and locating all the data assets that the organization owns, generates, or handles, and assigning them to different categories based on their sensitivity, value, and regulatory requirements1. Data inventory and classification is essential for DLP because it helps to determine the scope and objectives of the DLP solution, as well as the appropriate level of protection and monitoring for each data category2. Data inventory and classification also enables the organization to prioritize its DLP efforts based on the risk and impact of data loss or leakage3.

Option B is not correct because identifying approved data workflows across the enterprise is a subsequent step after conducting data inventory and classification. Data workflows are the processes and channels through which data are created, stored, accessed, shared, or transmitted within or outside the organization4. Identifying approved data workflows helps to define the normal and legitimate use of data, as well as to detect and prevent unauthorized or anomalous data activities5. However, before identifying approved data workflows, the organization needs to know what data it has and how it should be classified.

Option C is not correct because conducting a threat analysis against sensitive data usage is another subsequent step after conducting data inventory and classification. Threat analysis is the process of identifying and assessing the potential sources, methods, and impacts of data loss or leakage incidents. Threat analysis helps to design and implement effective DLP controls and countermeasures based on the risk profile of each data category. However, before conducting threat analysis, the organization needs to know what data it has and how it should be classified.

Option D is not correct because creating the DLP policies and templates is the final step after conducting data inventory and classification, identifying approved data workflows, and conducting threat analysis. DLP policies and templates are the rules and configurations that specify how the DLP solution should monitor, detect, report, and respond to data loss or leakage events. DLP policies and templates should be aligned with the organization’s business needs, regulatory obligations, and risk appetite. However, before creating the DLP policies and templates, the organization needs to know what data it has, how it should be classified, how it should be used, and what threats it faces.

The most reliable evidence is evidence obtained directly by the auditor through independent performance of procedures. ISACA guidance notes that higher-assurance audit work is achieved when evidence is produced directly by auditors, or at least strictly under their control, rather than being supplied by the entity being audited.

Option D is correct because independently performing manual procedures gives the auditor direct control over the evidence-gathering process and reduces reliance on the auditee or control owner. In audit theory and in ISACA-aligned practice, evidence obtained directly by the auditor is generally more reliable than evidence merely provided by the auditee.

Option A is strong evidence because it comes from an independent third party, but it is still inspected rather than generated directly by the auditor. It is generally very reliable, but not as strong as auditor-generated evidence through independent reperformance.

Option B is less reliable because system-generated evidence provided by a control owner still depends on the completeness and integrity of what was selected and presented by the auditee.

Option C is the least reliable among the plausible choices because critical data received from an auditee is subject to the greatest dependence on management representation and auditee-controlled extraction.

Therefore, D is the best answer because evidence generated through procedures performed independently by the auditor is the most reliable.

 The best recommendation to mitigate the risk of eavesdropping associated with an API integration implementation is to implement Transport Layer Security (TLS). TLS is a cryptographic protocol that provides secure communication over a network by encrypting the data in transit and authenticating the parties involved. TLS can prevent unauthorized parties from intercepting, modifying or tampering with the data exchanged between the API endpoints. Encrypting the XML file, implementing SOAP, and masking the API endpoints are not sufficient to mitigate the risk of eavesdropping, as they do not provide end-to-end encryption or authentication for the API communication. References: IS Auditand Assurance Tools and Techniques, CISA Certification | Certified Information Systems Auditor | ISACA

The correct answer is C. The impact on business processes has not been evaluated.

The auditor’s greatest concern is not simply that the contract became cheaper or that incident resolution time increased. The key concern is whether management evaluated the business impact of the longer incident resolution time. A longer incident resolution period may affect system availability, customer service, operational processing, contractual commitments, regulatory obligations, or business continuity.

ISACA defines a service level agreement as an agreement between a service provider and customer that defines minimum performance targets for a service and how those targets will be measured. ISACA’s CISA Exam Content Outline includes IT vendor management, IT service level management, problem and incident management, and evaluating whether IT service management practices align with organizational requirements.

Option A may be a concern if the new contract violates security policy, but the question does not state that it does. Option B is not the greatest concern because failing to consider alternative cost reductions is a management efficiency issue, not the primary audit risk. Option D is a concern because the SLA should match the contract, but updating the SLA alone does not solve the more important issue: whether the changed incident response commitment is acceptable to the business.

In CISA terms, IT decisions should be evaluated based on business impact and alignment, not only cost savings. A cheaper SaaS contract may create unacceptable operational risk if slower incident resolution affects critical business processes.

The overall effectiveness of an organization’s disaster recovery planning process depends on how well the plan reflects the current and future needs and risks of the organization, and how well the plan is tested, communicated, and maintained. Among the four options given, the most important one for the IS auditor to verify is that management reviews and updates the plan annually or as changes occur.

A disaster recovery plan is not a static document that can be created once and forgotten. It is a dynamic and evolving process that requires regular review and update to ensure that it remains relevant, accurate, and effective. A disaster recovery plan should be reviewed and updated at least annually, or whenever there are significant changes in the organization’s structure, operations, environment, or regulations. These changes could affect the business impact analysis, risk assessment, recovery objectives, recovery strategies, roles and responsibilities, or resources of the disaster recovery plan. If the plan is not updated to reflect these changes, it could become obsolete, incomplete, or inconsistent, and fail to meet the organization’s recovery needs or expectations.

The other three options are not as important as reviewing and updating the plan, although they may also contribute to the effectiveness of the disaster recovery planning process. Contracting with a third party for warm site services is a possible recovery strategy that involves using a partially equipped facility that can be quickly activated in case of a disaster. However, this strategy may not be suitable or sufficient for every organization or scenario, and it does not guarantee the success of the disaster recovery plan. Scheduling an annual tabletop exercise is a good practice that involves simulating a disaster scenario and testing the plan in a hypothetical setting. However, this exercisemay not be enough to evaluate the feasibility or readiness of the plan, and it should be complemented by other types of tests, such as walkthroughs, drills, or full-scale exercises. Documenting and distributing a copy of the plan to all personnel is an essential step that ensures that everyone involved in or affected by the plan is aware of their roles and responsibilities, and has access to the relevant information and instructions. However, this step alone does not ensure that the plan is understood or followed by all personnel, and it should be accompanied by proper training, education, and awareness programs.

Therefore, reviewing and updating the plan annually or as changes occur is the best answer.

 The risk assessment process involves identifying the information assets that are at risk, analyzing the threats and vulnerabilities that could affect them, evaluating the impact and likelihood of a risk event, and determining the appropriate controls to mitigate the risk. The first step is to identify the information assets, as they are the objects of protection and the basis for the rest of the process. Without knowing what assets are at risk, it is not possible to assess their value, exposure, or protection level. References: ISACA Frameworks: Blueprints for Success

The effectiveness of an organization’s security awareness program can be measured by capturing data on changes in the way people react to threats, such as the ability to recognize and avoid social engineering attacks1. An increase in the number of phishing emails reported by employees indicates that they are more aware of the signs and risks of phishing, and are more likely to take appropriate actions to prevent or mitigate the impact of such attacks23.

Thebiggest riskin cloud migration isdata security, especially unauthorized access by the cloud provider.

Option A (Correct):The cloud providermanages and stores organizational data, meaning that abreach, insider threat, or improper accessposes amajor risk. Properencryption and access controlsare critical.

Option B (Incorrect):Whilemulti-tenancy risks exist, cloud providers typically implement strongisolation mechanismsbetween clients.

Option C (Incorrect):Increased dependency on the provider is aconcern, but the impact depends onservice agreements and redundancy measures.

Option D (Incorrect):Limiting the right to audit is acompliance issue, butdata security risksare more critical.

The major advantage of automating internal controls is to efficiently test large volumes of data, because automated controls can perform repetitive tasks faster, more accurately, and more consistently than manual controls. Automated controls can also provide audit trails and exception reports that facilitate the monitoring and evaluationof the control effectiveness12. Reviewing large value transactions, identifying transactions with no segregation of duties, and performing analytical reviews are possible benefits of automating internal controls, but not the major advantage. References: 1: CISA Review Manual (Digital Version), Chapter 5, Section 5.2.2 2: CISA Online Review Course, Module 5, Lesson 2

 The IS auditor’s primary focus when evaluating an organization’s offsite storage facility should be the adequacy of physical and environmental controls. Physical and environmental controls are essential to protect the offsite storage facility from unauthorized access, theft, fire, water damage, pests or other hazards that could compromise the integrity and availability of backup media. Shared facilities is something that the IS auditor should consider when evaluating the offsite storage facility, but it is not the primary focus. Results of business continuity plan (BCP) test or retention policy and period are things that the IS auditor should review when evaluating the organization’s BCP or backup strategy, not the offsite storage facility itself. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 388

The success rate of social engineering attacks directly measures the behavioral changes resulting from an information security awareness program. Employees who are aware and informed are better equipped to identify and thwart such attacks.

Reduction in Reported Incidents (Option A):This may indicate underreporting rather than program effectiveness.

Reduction in Cost of Maintaining the Program (Option C):This reflects cost efficiency, not program effectiveness.

Reduction in Number of Attacks (Option D):The number of attacks is beyond the control of awareness programs and does not reflect their impact.

The best recommendation to prevent unauthorized access to a highly sensitive data center by piggybacking or tailgating is to use an airlock entrance. An airlock entrance is a type of access control system that consists of two doors that are interlocked, so that only one door can be opened at a time. This prevents an unauthorized person from following an authorized person into the data center without being detected. An airlock entrance can also be integrated with other security measures, such as biometrics, card readers, or PIN pads, to verify the identity and authorization of each person entering the data center.

Biometrics (option A) is a method of verifying the identity of a person based on their physical or behavioral characteristics, such as fingerprints, iris scans, or voice recognition. Biometrics can provide a high level of security, but they are not sufficient to prevent piggybacking or tailgating, as an unauthorized person can still follow an authorized person who has been authenticated by the biometric system.

Procedures for escorting visitors (option B) is a policy that requires all visitors to the data center to be accompanied by an authorized employee at all times. This can help prevent unauthorized access by visitors, but it does not address the risk of piggybacking or tailgating by other employees or contractors who may have legitimate access to the building but not to the data center.

Intruder alarms (option D) are devices that detect and alert when an unauthorized person enters a restricted area. Intruder alarms can provide a deterrent and a response mechanism for unauthorized access, but they are not effective in preventing piggybacking or tailgating, as they rely on the detection of the intruder after they have already entered the data center.

The best answer is D. To document relationships between configuration items.

ISACA’s configuration management guidance identifies the value of a CMDB in maintaining information about configuration items and their relationships. That relationship view is what supports effective impact analysis, change management, incident response, and dependency understanding across the environment.

Option A is too narrow. Option B describes monitoring rather than configuration management. Option C may be one data element in some environments, but the defining value of a CMDB is not physical location tracking. The central purpose is documenting configuration items and how they relate to one another.
