What is the purpose of checking the checkbox regarding impersonation for ACLs?

The purpose of checking the checkbox regarding impersonation for Access Control Lists (ACLs) is to prevent impersonating users from seeing sensitive HR profile information. In ServiceNow, impersonation allows a user (typically an administrator or support staff) to take on the role of another user to troubleshoot issues, assist users directly, or perform tasks on their behalf.

By ensuring that sensitive HR data is protected through appropriate ACL settings, organizations can maintain compliance with privacy regulations and protect sensitive information from unauthorized access. When impersonation is activated, if the ACL is configured correctly with the checkbox checked, it ensures that even if someone is impersonating another user, they will be restricted from accessing sensitive HR profile information unless they have the necessary permissions. This measure provides an additional layer of security, ensuring that user data remains confidential and accessible only to those who are authorized.
