What should an IS auditor focus on when planning the audit of new systems?

Focusing on the highest risk areas based on a risk assessment is crucial when planning the audit of new systems. This approach ensures that the auditor concentrates their efforts on the components that could significantly impact the organization's operations, security, and compliance. By identifying and prioritizing risk areas, the auditor can allocate resources effectively to address vulnerabilities that may affect the integrity, confidentiality, or availability of the system and its data.

When assessing new systems, understanding the associated risks helps in determining the critical aspects that require in-depth analysis. Given that new systems may introduce unknown factors and potential weaknesses, addressing these high-risk areas early in the audit process aids in mitigating potential issues before they escalate. This methodical focus supports better decision-making, enhances audit efficiency, and ultimately contributes to a stronger overall risk management framework.

While specific requests from management might highlight areas of immediate concern, they may not provide a comprehensive view of risk. Similarly, reviewing systems included in the previous audit may not be pertinent if those systems have significantly changed or new systems have been introduced. Lastly, while following recommended industry practices can guide the audit process, it does not replace the need to assess the risk levels associated with specific systems. Thus, concentrating on identified risk areas ensures that the audit is not only relevant
