service plan - error on save

[EricVis]

I'm getting this popup warning when saving changes to my default service plan (plesk 11 with all updates applied)

There are settings that conflict with the server-wide security policy. Are you sure you want to continue?
If you really want to override the security policy and apply the conflicting settings, click Yes. Otherwise, click No, and then click the link 'apply secure setting preset' to bring the settings in accordance with the server-wide security policy. The following settings conflict with the policy:
- undefined

Where exactly do you set the "server-wide security policy"?
