The IIA Standards state that conformance with standards related to independence and objectivity is not dependent upon the size of the internal audit activity. All internal audit functions, regardless of their size, must adhere to the principles of independence and objectivity to ensure that their work is unbiased and free from undue influence. This is fundamental to the credibility and reliability of the internal audit activity's work and findings. While small internal audit activities may face unique challenges, such as resource limitations, these challenges do not exempt them from maintaining these core principles.References:

Detective internal controls are a limitation in fraud management because they are not designed to prevent fraud but to identify fraud after it has occurred. Their primary purpose is to detect and provide feedback on incidents of fraud, thereby allowing corrective action to be taken. However, they do not stop the initial occurrence of fraudulent activities.References: IIA guidance on types of controls and their effectiveness in fraud prevention.
