HIPS->Protected Objects

The help manual is not very clear or a bit confusing on how things exactly work for “HIPS->Protected Objects”

So some short questions related to items added to:

PROTECED FILES
File/folder read access : both trusted and untrusted applications.
File/folder write access : only trusted applications, untrusted applications can’t modify or delete.

REGISTRY KEYS
Registry keys read access : both trusted and untrusted applications
Registry keys write access : only trusted applications, untrusted applications can’t modify or delete.

Is the above summary correct?

protect files (not read or acess direct)
protect registry keys (not read or acess direct)
NOTE: Applications list protect files or registry, but not acess or read. :-TU
