General Question: Warehouse Bar-coding, how secure is?
Posted on 2005-04-17
Not sure if I’m in the right forum…if not please direct; thanks!
I good friend of mine, recently stated that the Cdn military has not implement bar-coding and asset-tracking solutions in the supply chain, and warehouses, because of lack of security with bar-coding. Essentially, I’m told, that if a hacker gets into the supply bar-coding system….which they say is easy; they can then easily have access throughout all other systems…finance, operations, etc….
To be honest this just doesn’t seem right to me; most [if not all] of the big chains, Wal-Mart, as an example, must, I assume uses bar-coding for asset tracking, which seems the logical thing to do, and makes good business sense. So based on the military’s train of thought being true, then why would other large inventory driven businesses use bar-coding, or do they accept that their system(s) are vulnerable, but any damage done by such attacks, is an acceptable trade off for accurate accountability of asset tracking.
Just doesn’t seem right. The military uses Firewalls, and I would think they must have a layered system to prevent any attacks from entering, and I would further think that a system would be in place to divide servers, so that if a hacker got into one system…in this case the Supply-chain, they would be unable to get into another, or are they all linked in some open manner. I don’t know…are all the LANs connected – perhaps; it still doesn’t seem right, but I don’t know enough about LANs, MANs, WANs, Servers, or Bar-coding and asset tracking, and/or securing such system to be of any value.
So, I guess my question is; How secure are Bar-coding systems, and what issues of security would make the military not use them?
I’m just curious about this whole issue, and would appreciate a better understanding!
Thanks in advance.
