Which admin role is required to make changes to High Security Settings?

`high_sec_admin` is not a standard, recognized role in ServiceNow for this purpose.

`sn_acl_admin` is not a standard, recognized role in ServiceNow for managing high security settings; ACLs are managed by `security_admin` for elevated ones.

The `admin` role has broad access but is explicitly restricted from modifying High Security Settings to enforce a separation of duties.

The `security_admin` role is an elevated privilege role designed to manage high security settings, including modifying Access Control Lists (ACLs) with `security_admin` required and other critical security configurations, providing a segregation of duties from the general `admin` role. This separation ensures that only authorized personnel can make sensitive security changes, enhancing the platform's overall security posture.
