An IS auditor finds that the process for removing access for terminated employees is not...

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:
