CISA Exam Dumps - Certified Information Systems Auditor

Integration testing is the best way to ensure that an application is performing according to its specifications, because it tests the interaction and compatibility of different modules or components of the application. Unit testing, pilot testing and system testing are also important, but they do not cover the whole functionality and integration of the application as well as integration testing does. References: CISA Review Manual (Digital Version)1, Chapter 4, Section 4.2.3

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

 Problem management is an IT service management activity that is most likely to help with identifying the root cause of repeated instances of network latency. Problem management involves analyzing incidents that affect IT services and finding solutions to prevent them from recurring or minimize their impact. Change management is an IT service management activity that involves controlling and documenting any modifications to IT services or infrastructure. Incident management is an IT service management activity that involves restoring normal service operation as quickly as possible after an incident has occurred. Configuration management is an IT service management activity that involves identifying and maintaining records of IT assets and their relationships. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 334

 Partitioning the work environment from personal space on devices. This would best maintain information security without compromising employee privacy by creating a separate and secure area on the personal mobile devices for work-related data and applications. This way, the organization can protect its information from unauthorized access, loss, or leakage, while respecting the employees’ personal data and preferences on their own devices.

The other options are not as effective as option B in balancing information security and employee privacy. Option A, installing security software on the devices, is a good practice but may not be sufficient to prevent data breaches or comply with regulatory requirements. Option C, preventing users from adding applications, is too restrictive and may interfere with the employees’ personal use of their devices. Option D, restricting the use of devices for personal purposes during working hours, is impractical and difficult to enforce.

 The greatest concern for an IS auditor when a post-implementation review was conducted by issuing a survey to users is that the survey questions did not address the scope of the business case. A post-implementation review is a process of evaluating the outcomes and benefits of a project after it has been completed and implemented. A post-implementation review can help to assess whether the project met its objectives, delivered its expected value, and satisfied its stakeholders1. A survey is a method of collecting feedback and opinions from users or other stakeholders about their experience and satisfaction with the project. A survey can help to measure the user acceptance, usability, and functionality of the project deliverables2. A business case is a document that justifies the need for a project based on its expected benefits, costs, risks, and alternatives. A business case defines the scope, objectives, and requirements of the project and provides a basis for its approval and initiation3. Therefore, an IS auditor should be concerned if the survey questions did not address the scope of the business case, as it may indicate that the post-implementation review was not comprehensive, relevant, or aligned with the project goals. The other options are less concerning or incorrect because:

A. The survey results were not presented in detail to management is not a great concern for an IS auditor when a post-implementation review was conducted by issuing a survey to users, as it is more of a communication or reporting issue than an audit issue. While presenting the survey results in detail to management may help to inform them about the project performance and outcomes, it does not affect the validity or quality of the post-implementation review itself.

C. The survey form template did not allow additional feedback to be provided is not a great concern for an IS auditor when a post-implementation review was conducted by issuing a survey to users, as it is more of a design or format issue than an audit issue. While allowing additional feedback to be provided may help to capture more insights or suggestions from users, it does not affect the validity or quality of the post-implementation review itself.

D. The survey was issued to employees a month after implementation is not a great concern for an IS auditor when a post-implementation review was conducted by issuing a survey to users, as it is more of a timing or scheduling issue than an audit issue. While issuing the survey to employees sooner after implementation may help to collect more accurate and timely feedback from users, it does not affect the validity or quality of the post-implementation review itself. References: Post Implementation Review - ISACA, Survey - ISACA, Business Case - ISACA

 The greatest risk of using a reciprocal site for disaster recovery is the inability to utilize the site when required. A reciprocal site is an agreement between two organizations to provide backup facilities for each other in case of a disaster. However, this arrangement may not be reliable or enforceable, especially if both organizations are affected by the same disaster or have conflicting priorities. Therefore, the IS auditor should recommend that management consider alternative options for disaster recovery, such as dedicated sites or cloud services12. References:

 The first step in the incident response process for a suspected breach is to research the validity of the alerted breach. An incident response process is a set of procedures that defines how to handle security incidents in a timely and effective manner. The first step in this process is to research the validity of the alerted breach, which means to verify whether the alert is genuine or false positive, to determine the scope and impact of the incident, and to gather relevant information for further analysis and action. Informing potentially affected customers of the security breach, notifying business management of the security breach, and engaging a third party to independently evaluate the alerted breach are also steps in the incident response process, but they are not the first step. References:

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 information security policy should also be focused on the business needs and requirements of the organization, rather than on technical details or specific 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 sufficient to 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 should be 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:
