SO vs DSO

Recently I was asked if a object supported dynamic loading. I believe
the underlying question is "shared object" versus "dynamic shared
object". The best I can tell, I getting back lots of useless
information during a search.

(1) How does on tell a SO and DSO apart?
(2) How does one stop an adversary from using them incorrectly?

I was thinking a flag might be present, similar to RFC3514 - The
Security Flag in the IPv4 Header. That is, there's a gentleman's
agreement if a particular bit is set, the attacker will not misuse the
object.
