Access control is a critical aspect of an organization’s security posture, and ensuring that only authorized individuals can access sensitive data or systems is crucial.
A.9.2.1 User registration and de-registration is a crucial element of access control.
It involves creating and removing user accounts from an organization’s systems and networks.
This article will explore the importance of user registration and de-registration, the checklist that can be used to assess compliance with this control, and the benefits of implementing this control effectively.
Sample Checklist:
- Check if access control policy and procedures cover user registration and de-registration.
- Check if unique user IDs are assigned to each user, generated based on a request workflow with appropriate approvals and records.
- Verify that user IDs of leavers are disabled immediately based on a workflow.
- Check if Security Administration has effective links with HR plus Procurement for prompt notification when workers leave or move on.
- Ensure periodic review/audit to identify and suspend redundant user IDs.
- Verify that suspended IDs are deleted after confirming that they are no longer needed.
- Ensure that user IDs are not reassigned to other users.
- Check how an audit trail is maintained if registration and de-registration is a manual process.
- Verify that the timing of de-registering an account is not counterproductive to the business.
Conclusion:
A.9.2.1 User registration and de-registration is a critical control in ensuring that only authorized individuals have access to an organization’s systems and data.
An effective user registration and de-registration process can help to prevent unauthorized access, data breaches, and other security incidents.
