There is a rough standard for what local and remote mean.  The
standard may not be as precise as you'd like.  Using old terms with
new definitions doesn't advance the debate, it generates confusion.
This is especially the case when you haven't rigorously defined the
proposed new meanings of the terms.

I think all this conversation is doing is showing that the terms 'local' and
'remote' are vague and maybe not terribly useful anymore.

I've long advocated 'credentialed' to refer to attacks where a user of
the system can execute the attack, and 'anonymous' or
'non-credentialed' to refer to refer to attacks on servers, such as
httpd, ftpd, or named.  These attacks can be launched by anyone, from
anywhere (barring interference from firewalls or the like).

That'd be a good start.  In most cases what people really want to know when
they look at 'remote' or 'local' attacks is whether any random person on the
Internet can execute the attack, or whether they only have to worry about
their own users.  This is especially true at small sites where if a local
user acts up, the sysadmin can just go dope slap them. ;)  I take it under
your system, the NASM vulnerability would be considered "credentialed"?
