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.

The auditor should be most concerned with the impact AI will have on enterprise architecture (EA) when reviewing a project to replace multiple manual data entry systems with an AI system. EA is a comprehensive framework that defines the structure, components, relationships, and principles of an organization's IT environment. EA can help to align the IT strategy with the business strategy and ensure the coherence, consistency, and integration of the IT systems and services. Replacing manual data entry systems with an AI system may have significant implications for the EA, such aschanging the business processes, data flows, security requirements, performance standards, or governance models. The auditor should assess whether the project has considered the impact of AI on EA and whether the EA has been updated accordingly. References:

A backlog consumption report is a report that shows the amount of work that has been completed and the amount of work that remains to be done in a project. It is a useful tool for measuring the progress and performance of a web-based customer service application development project, as it can indicate whether the project is on track, ahead or behind schedule, and how much effort is required to finish the project. A backlog consumption report can also help identify any issues or risks that may affect the project delivery. Critical path analysis reports, developer status reports and change management logs are also helpful for evaluating a project, but they are not as helpful as a backlog consumption report, as they do not provide a clear picture of the overall project status and completion rate.
