Re: snmpconf Issue #17: security questions


http://www.snmp.com/snmpconf/mailing-list/msg00661.html has the 
thread in question.

There have been two messages thus far.  That is simply not enough 
to make any judgement on so-called "consensus".  So... I'm going
to give my viewpoint.  Other voices welcome.

*chair hat off, technoweeníe hat on*
 I personally believe that it's going to be very difficult to do
 better than the DISMAN folks have done and am inclined to leave
 the security model as it is (since that seems to be what DISMAN
 decided - Juergen?  Randy?).

 There may be reason to wordsmith to some degree, but operating
 under the credentials of the last writer seems to be the right
 thing to do given what I know now.

That's not what happens.  Who _wrote_ the code and who _writes_
the code into the code tables are two entirely separate issues.

Keep in mind, of course, that the code tables are protected by
the VACM.  So, if you only want joe to write to the table, you
can do that.  If you set it up so that both joe and mary are
allowed to write, then you'd better be sure joe and mary know
what they're doing.  I see the VACM as the solution to what
you're describing.

So, I believe we have it right - or the best we can do - already.

With kind regards,
