default security
Security settings that you want used every time a new instance of the object is created. Default records for formulas and items contain security information and other data.
You can specify security for items and formulas through the default records.
Security controls the read/write/copy/delete
privileges
for the owner (creator), group member, and non-group member for this type of object.
When a user creates a new object or copies an object of this type, the default security
is applied.
