Certified Information Systems Auditor 2025 – 400 Free Practice Questions to Pass the Exam

The consequence of poor due diligence in an IT audit process is that it can lead to a heightened risk of significant security breaches. Due diligence is crucial because it involves thoroughly assessing and understanding an organization's IT processes, controls, and security measures. When due diligence is not carried out effectively, vulnerabilities may remain undetected, leaving systems exposed to threats.

In the context of an IT audit, failing to identify and understand existing weaknesses can lead auditors to overlook critical areas that require attention. This oversight can allow malicious actors to exploit these weaknesses, resulting in unauthorized access, data loss, or disruption of services. Therefore, conducting comprehensive due diligence is essential for mitigating risks and ensuring that security controls are robust and effective.

The other options do not align with the negative outcomes associated with poor due diligence, as they suggest positive impacts or efficiencies rather than identifying risks.
