The primary task of the internal auditor is to evaluate the security of the LAN specific to the finance department where sensitive financial data and models are managed. Examining the physical security, user access controls, and user feedback regarding the system's security are all relevant to this task. However, assessing the security levels of other LANs in the company falls outside the specific scope of auditing the LAN used by the finance department.
Testing the accuracy of cost-of-quality reports provided to management focuses on ensuring the reliability and integrity of information. It is essential that the information contained in such reports is accurate and trustworthy so that management can make informed decisions based on dependable data.
In the context of pollution prevention, the most effective approach is often elimination at the source, which involves modifying processes to reduce or eliminate waste production entirely. After elimination, recycling and reuse should be considered, as they prevent waste by turning it into usable materials again. The next step is recovery as a usable product, which involves processing waste to retrieve valuable components. Energy conservation can also play a role in minimizing waste indirectly by making manufacturing processes more efficient. Treatment and disposal are generally considered last resorts since they deal with waste only after it has been generated.
