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. Asurvey 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.

The best way to mitigate the risk associated with unintentional modifications of complex calculations in end-user computing (EUC) is to execute copies of EUC programs out of a secure library. This will ensure that the original EUC programs are protected from unauthorized changes and that the copies are run in a controlled environment. A secure library is a repository of EUC programs that have been tested, validated, and approved by the appropriate authority. Executing copies of EUC programs out of a secure library can also help with version control, backup, and recovery of EUC programs. Having an independent party review the source calculations, implementing complex password controls, and verifying EUC results through manual calculations are not as effective as executing copies of EUC programs out of a secure library, as they do not prevent or detect unintentional modifications of complex calculations in EUC.

The primary responsibility of a project steering committee is to provide regular project updates and oversight.
A project steering committee is an advisory group that consists of senior stakeholders and experts who offer guidance and support to a project manager and their team. The steering committee is mainly concerned with the direction, scope, budget, timeline, and methods used to realize a given project1.
One of the key roles of a steering committee is to monitor the progress and performance of the project and ensure that it aligns with the business objectives and stakeholder expectations. The steering committee also provides feedback, advice, and recommendations to the project manager and helps them resolve any issues or challenges that may arise during the project lifecycle. The steering committee communicates regularly with the project manager and other stakeholders through meetings, reports, and presentations23.
Therefore, providing regular project updates and oversight is the primary responsibility of a project steering committee.

The only thing that can be provided by asymmetric encryption is nonrepudiation. Nonrepudiation is the ability to prove that a message or transaction was originated or authorized by a specific party. Asymmetric encryption uses a pair of keys: a public key and a private key. The public key can be shared with anyone, while the private key is kept secret by the owner. If a message is encrypted with the sender's private key, only the sender's public key can decrypt it. This proves that the message was sent by the sender and not by anyone else. This is called digital signature and it provides nonrepudiation. Asymmetric encryption can also provide information privacy by encrypting a message with the receiver's public key, so that only the receiver's private key can decrypt it. However, information privacy can also be provided by symmetric encryption, which uses a single key to encrypt and decrypt messages. References:

The internal audit manager should have a reporting line to the audit committee, which is an independent body that oversees the internal audit function and ensures its objectivity and accountability. Reporting functionally to a senior management official may compromise the independence and clarity of the internal audit reporting process, as senior management may have a vested interest in the audit results or influence the audit scope and priorities. *References: According to the ISACA IT Audit and Assurance Standards, Guidelines and Tools and Techniques for IS Audit and Assurance Professionals, section 1002 Independence, "The chief audit executive (CAE)should report functionally to the board or its equivalent (e.g., audit committee) and administratively to executive management." 1
