SharePoint site security configurations for Defender Cloud Apps Admin Quarantine Feature

Referring to Microsoft official documentation below which is very high-level, has anyone done/would recommend hardening or applying security measures to secure the SharePoint site dedicated for "Admin Quarantine" purpose?.

It shouldn't be just as simple as creating a separate site and setting in the Defender portal as this should not be exposed to the rest of the organization, in my view. Shouldn't we at a minimum, restrict the permissions of the site?

Any ideas are greatly appreciated !

Thank you!
