The most significant risk from this observation is that access rights may not be removed in a timely manner. If the process for removing access for terminated employees is not documented, there is no clear guidance or accountability for who, how, when, and what actions should be taken to revoke the access rights of the employees who leave the organization. This could result in delays, inconsistencies, or omissions in removing access rights, which could allow terminated employees to retain unauthorized access to the organization’s systems and data. This could compromise the security, confidentiality, integrity, and availability of the information assets. References:

The most important control to assess in an audit of an organization’s accounts payable processes is segregation of duties between issuing purchase orders and making payments. Segregation of duties is a principle that requires different individuals or departments to perform different tasks or functions within a process, in order to prevent fraud, errors, or conflicts of interest. In the accounts payable process, segregation of duties between issuing purchase orders and making payments ensures that no one person can initiate and complete a transaction without proper authorization and verification. This reduces the risk of duplicate payments, overpayments, unauthorized payments, or payments to fictitious vendors.

The IS auditor’s most important course of action after finding that several similar incidents were logged during the audit period is to determine if a root cause analysis was conducted. A root cause analysis is a systematic process that identifies the underlying causes of system failures or incidents. A root cause analysis can help to prevent recurrence of similar incidents, improve system performance and reliability, and enhance incident management processes. The IS auditor should evaluate whether a root cause analysis was performed for each incident, whether it was timely and thorough, and whether it resulted in effective corrective actions.
