This should result in a finding because it violates the best practice of setting rules for groups rather than users. According to one of the web search results1, using group permissions instead of individual permissions can simplify the management and maintenance of ACLs, reduce the risk of human errors, and ensure consistency and compliance. Individual permissions can create conflicts, confusion, and security gaps in the ACLs. Therefore, the IS auditor should report this as a finding and recommend using group permissions instead.

 A differential backup scheme is the best option when storage media is limited, as it only backs up the data that has changed since the last full backup. This reduces the amount of storage space required and also simplifies the restoration process, as only the last full backup and the last differential backup are needed. A real-time backup scheme would require continuous replication of data, which would consume a lot of storage space and network bandwidth. A virtual backup scheme would create a snapshot of the data at a point in time, but it would not reduce the storage space required, as it would still need to store the changes made to the data. A full backup scheme would back up all the data every time, which would require the most storage space and also take longer to complete. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 405

 The most important thing for an IS auditor to look for in a project feasibility study is an assessment of whether the expected benefits can be achieved. A project feasibility study is a preliminary analysis that evaluates the viability and suitability of a proposed project based on various criteria, such as technical, economic, legal, operational, and social factors. The expected benefits are the positive outcomes and value that the project aims to deliver to the organization and its stakeholders. The IS auditor should verify whether the project feasibility study has clearly defined and quantified the expected benefits, and whether it has assessed the likelihood and feasibility of achieving them within the project scope, budget, schedule, and quality parameters. The other options are also important for an IS auditor to look for in a project feasibility study, but not as important as an assessment of whether the expected benefits can be achieved, because they either focus on specific aspects of the project rather than the overall value proposition, or they assume that the project will be implemented rather than evaluating its viability. References: CISA Review Manual (Digital Version)1, Chapter 4, Section 4.2.1

 The most effective way for an organization to help ensure agreed-upon action plans from an IS audit will be implemented is to ensure ownership is assigned. This means that the management of the audited area should accept responsibility for implementing the action plans and report on their progress and completion to the audit committee or senior management. This will ensure accountability, commitment, and follow-up for the audit recommendations34. References: 3: CISA ReviewManual (Digital Version), Chapter 1: The Process of Auditing Information Systems, Section 1.6: Reporting, page 41 4: CISA Online Review Course, Module 1: The Process of Auditing Information Systems, Lesson 1.6: Reporting
