RE: Where are all of the /400's going. (was RE: QUSER on ODBC requests)

It's late so I'll wait until tomorrow to elaborate on the tool, but as far
as hacking the AS/400 serial number, yes it can and has been done. If you
know an address or two it's almost trivial.

Walden,

Is that VB?

VERY interested in this tool, if you wanna elaborate.

==> But here's the thing:  (I'm NOT contradicting you, but just asking the
question.)  Has it ever been done AND/OR IS it theoretically possible: COULD
a 400 machine serial number be hacked...?!?  I guess I'm asking if there's
ANY WAY CONCEIVABLE?  I think this is a key question.

| I'm not sure if you could keep ahead of the hackers, but I'd guess
| not. I forgot about CPU serial number, but my intent is to include it
| in the tool too (this isn't theory for me). Since we can safely say
| that this tool will be used in the corporate environment I don't see a
| problem saying that the PCs involved must allow the retrieval of the
| Intel serial number. AFAIK, there is no way to emulate or override the
| CPUID machine instruction so this
| would be very difficult to hack.
|
| In a COM environment you'd use to tool something like:
|
| Dim upm as new ProfileManager
| Dim usr as string
| Dim pwd as string
|
| upm.GetProfile("AS400Name", "ServiceName")
| Usr = Upm.User
| Pwd = Upm.Password
| Set upm = nothing
|
| ServiceName is site-specific and could include things like "EndOfMonth
| Accounting FTP" or "VRU Password Download" or whatever floats your
| boat.

| Walden,
|
| Sounds like a keeper, to me...  Thanks...!
|
| I would add processor serial number to the criteria to validate, at
| least amongst 400s and other platforms that support this.  (Intel
| could have, but was required by the user community to allow this
| feature to be disabled at the user's option.)
|
|
| But I'd like to take this to the next level...  (Again, don't know the
| technology.)  I'd like to know more about the issues surrounding "Can
| it be defeated, of course..."...
|
| I think a part of the answer to this is collaboration amongst trusted
| users...  Don't know any specifics, but it would seem that different
| methods of security should be rotated, and continually evolved, to
| give the hackers
| a moving target.  Spread the security methods around, along the lines that
| the DNS addresses are spread through the Net (although at a MUCH quicker
| rate).
|
|
| My question is whether it's possible (theoretically AND
| practically) to keep
| the security methods evolving fast enough to **simulate** staying one
| step ahead of the hackers...?!?  (You'll always have a small minority
| of crooked insiders, so you can only "simulate" staying ahead of the
| hackers, AFAIK.)

| |
| | OK, so have the pc program ask the as/400 for a valid userid and
| | password. The 400 could validate that the request was valid (remote
| | ip, MAC, time,
| | etc.) and return a user and password. A 5 second counter would
| then start
| | and when it expires the password for that user would be
| changed. Can it be
| | defeated, of course, but you'd have to set your ip, mac address and
| | ask for the password at the specific date and time that's much more
| secure than a
| | user called 'transfer' with a password of 'transfer'.

| | Rob,
| |
| | I'd sure like to see an acceptable solution to this one, myself...
| |
| | Hardcode passwords in code..: no good at all...!  But have password
| | keyed in on every batch FTP and Domino app use...:  AIN'T GONNA
| | HAPPEN...!
