CISA Exam Dumps - Certified Information Systems Auditor

The most important consideration for an IS auditor when assessing the adequacy of an organization’s information security policy is the business objectives. An information security policy is a document that defines the organization’s approach to protecting its information assets from internal and external threats. It should align with the organization’s mission, vision, values, and goals, and support its business processes and functions1. An informationsecurity policy should also be focused on the business needs and requirements of the organization, rather than on technical details orspecific solutions2.

The other options are not as important as the business objectives, because they do not directly reflect the organization’s purpose and direction. IT steering committee minutes are records of the discussions and decisions made by a group of senior executives who oversee the IT strategy and governance of the organization. They may provide some insights into the information security policy, but they are not sufficientto evaluate its adequacy3. Alignment with the IT tactical plan is a measure of how well the information security policy supports the short-term actions and projects that implement the IT strategy. However, the IT tactical plan itself shouldbe aligned with the business objectives, and not vice versa4. Compliance with industry best practice is a desirable quality of an information security policy, but it is not a guarantee of its effectiveness or suitability for the organization. Industry best practices are general guidelines or recommendations that may not apply to every organization or situation. An information security policy should be customized and tailored to the specific context and needs of the organization. References:

 The IS quality assurance (QA) group is responsible for ensuring that program changes adhere to established standards. Program changes are modifications made to software applications or systems to fix errors, improve performance, add functionality, or meet changing requirements. Program changes should follow established standards for documentation, authorization, testing, implementation, and review. The IS QA group is responsible for verifying that program changes comply with these standards and meet the expected quality criteria. Designing procedures to protect dataagainst accidental disclosure; ensuring that the output received from system processing is complete; and monitoring the execution of computer processing tasks are not responsibilities of the IS QA group. References: [ISACA CISA Review Manual 27th Edition], page 304.

 Using a continuous auditing module is an audit procedure that would provide the best assurance that an application program is functioning as designed. A continuous auditing module is a software tool that performs automated and continuous testing and monitoring of an application program’s inputs, outputs, processes, and controls. A continuous auditing module can help to verify the accuracy, completeness, validity, reliability, and timeliness of the application program’s data and transactions. A continuous auditing module can also help to identify and report any errors, anomalies, deviations, or exceptions in the application program’s performance or compliance.

The other options are not as effective or relevant as using a continuous auditing module for providing assurance that an application program is functioning as designed. Interviewing business management is a technique for obtaining information and opinions from the users or owners of the application program, but it does not directly test or verify the functionality or quality of the application program. Confirming accounts is a technique for verifying the existence and accuracy of account balances or transactions, but it does not necessarily reflect the design or operation of the application program. Reviewing program documentation is a technique for examining the specifications,requirements, and procedures of the application program, but it does not provide evidence of the actual implementation or execution of the application program.

The best control to minimize the risk of unauthorized access to lost company-owned mobile devices is device encryption. Device encryption is a process that transforms data on a device into an unreadable format using a cryptographic key. Device encryption protects the data stored on the device from being accessed by unauthorized parties, even if they bypass the password or PIN protection. Device encryption can also prevent data leakage if the device is disposed of or recycled without proper data sanitization. Password or PIN protection is a basic control that prevents unauthorized access to the device by requiring a secret code or pattern to unlock it. However, password or PIN protection can be easily compromised by brute force attacks, shoulder surfing, or social engineering. Device trackingsoftware is a tool that allows the device owner or administrator to locate, lock, or wipe the device remotely in case of loss or theft. However, device tracking software depends on the device’s network connectivity and GPS functionality, which may not be available or reliable in some situations. Periodic backup is a process that copies the data from the device to another storage location for recovery purposes. Periodic backup can help restore the data in case of loss or damage of the device, but it does not prevent unauthorized access to the data on the device itself. References: CISA ReviewManual (Digital Version), Chapter 5: Protection of Information Assets, Section 5.4: Mobile Devices

The most appropriate control to prevent unauthorized retrieval of confidential information stored in a business application system is to enforce an internal data access policy. A data access policy defines who can access what data, under what conditions and for what purposes. It also specifies the roles and responsibilities of data owners, custodians and users, as well as the security measures and controls to protect data confidentiality, integrity and availability. By enforcing a data access policy, the organization can ensure that only authorized personnel can retrieve confidential informationfrom the business application system. Applying single sign-on for access control, implementing segregation of duties and enforcing the use of digital signatures are also useful controls, but they are not sufficient to prevent unauthorized data retrieval without a clear and comprehensive data access policy. References:

Capability maturity models (CMMs) are frameworks that help organizations assess and improve their processes in various domains, such as software development, project management, service delivery, and cybersecurity1. CMMs define different levels of process maturity, from initial to optimized, and describe the characteristics and best practices of each level. By using CMMs, organizations can benchmark their current processes against a common standard, identify gaps and weaknesses, and implement improvement actions to achieve higher levels of process maturity2. CMMs can also help organizations align their processes with their strategic goals, measure their performance, and increase their efficiency, quality, and customer satisfaction3.

Therefore, the use of CMMs would best enhance a process improvement program, as they provide a systematic and structured approach to evaluate and improve processes based on proven principles and practices. Option C is the correct answer.

Option A is not correct because model-based design notations are graphical or textual languages that help designers specify, visualize, and document the structure and behavior of systems4. While they can be useful for designing and communicating complex systems, they do not directly address the process improvement aspect of a program.

Option B is not correct because balanced scorecard is a strategic management tool that helps organizations translate their vision and mission into measurable objectives and indicators. While it can be useful for monitoring and evaluating the performance of a program, it does not provide specific guidance on how to improve processes.

Option D is not correct because project management methodologies are sets of principles and practices that help organizations plan, execute, and control projects. While they can be useful for managing the scope, schedule, cost, quality, and risk of a program, they do not focus on the process improvement aspect of a program.
