I guess it's a question of when are you secure enough? Note that I said
changing the serial number was "almost trivial" not "almost trivial without
secofr-level access". If someone has secofr-level access then I wouldn't be
too concerned with the serial number issue. <G> Digital certificates,
encryption (IPSEC, SSL, PGP, DES, etc.) could all add to the level of
security, but if it's coded somewhere then it's hackable. It's not until you
add in things like bio-metrics (retina, fingerprint, etc.) that you get to a
degree of unhackability and even then, I don't need you, just your eye or
finger.

Can white-hat hackers help, maybe. But it would also be up to the owner of
the code to make changes according to the findings of the community and the
owner would need development dollars to make those changes. Would the
community be willing to spend development money (in the form of maintenance
fees) to fix a hole that 1 in a million people might find? Probably not. A
hole that 1 in 10 might find, probably yes. A hole that 1 in 1000 might
find? Hard to say.

As far as details of the Profile Manager tool go, yes that is vb code in the
example. VB makes a great test platform for COM since it's so damn easy.
I'll contact you off-list with more details on the tool itself since I'd
hate to be accused of posting something that might tarnish the dignity of
this forum! <G>

Walden,

Dag...:-( ! !  (But thanks for info.)

I didn't know, but was afraid of that...

So the question becomes, CAN that be prevented...?!?  Most likely by the
services of white-hat hackers...?  And a method of rapidly delivering new
security methods, as weaknesses are (hopefully pro-actively) discovered, a
la DNS...

| 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

| | 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'.
