That depends if you're absolutely sure you never want to use that door or not.

Quote: How far would you trust open source
I think you always have to keep in mind where the source came from (legitimate sources like RedHat or Canonical) but it's also really important for your developers to understand the code, not just copy it and call it a day. Probably the biggest mistake I've seen people make over the span of my career (as to security) is copy and paste without understanding what that code does.
Quote: The operating system (would you use Linux?)
Of course... Linux is already one of the most widely used operating systems for embedded systems. The government uses it quite extensively as well.

I NEVER use any open source unless I can review the code myself.
If it's not broken, fix it until it is

The line would be drawn at any non-validated code, and it would take quite some time to validate a small linux distro.
..but without it, one could hardly give any guarantees on what the software actually does.

If you didn't write it yourself you would need to test the heck out of it to;
1) Make sure it does what's needed
2) Security, Security, Security...
3) Is it stable
And working up the list...yes I would definitely use Unix, Linux or a derivative!

I would trust these standard software components, if there have a sound source and are professionally maintained. I would consider making some maintainance support with the originators.
An indepedent code review is absolut necessary for all code above these standard components.
I separate between the foundation software (OS, database, tools) and the specialized software (which runs the transactions and encryption). The software which has confidential data is at risk. Take care about the encryption ie the keys.

Is this the machine or processing server? Most ATM's are/were running on Windows and only have point-to-point connection with the server and it is the server, that communicates with the other banks, that can be a possible vulnerability. From memory the PIG defines the parameters within which the ATM should be working. All nodes on the network have an encryption key and unless the server can recognise that device there is little room to fake your way in. I haven't worked on retail for a few years but if you've got any questions ping me and I'll do what I can to clarify.

One of my most traumatic memories was created when I walked up to an indoor ATM for my bank, and it was in a continuous reboot cycle. I recognized what was going on; the ATM software ran under OS/2. Whoever wrote the application filled OS/2's CONFIG.SYS file with entries for every possible device driver, most of which failed. One of the failures was causing a hardware reset, which triggered the continual reboot.
Awe-inspiring, to say the least.

Well that is the definition of a phobia, it is irrational, a response out of proportion to the danger.
Although people screaming at small insects and such like almost always isn't phobia at all, just an aversion.

I've never understood people who say they can't understand this or that mental disorder. You're not supposed to understand, if you did then you would have it.
Now you have it, you understand.

Nope, still don't get it.
A mate of mine always posts on Facebook after some hideous crime against children "I can't understand how anyone could do this". Of course not you fool, if you could understand how to murder small children then would be the time to worry, not now when you cannot.

It's just an expression. You shouldn't take it literally.

Herself does that as well: asks me "how can he do something like that?" and I'm all "how the elephant should I know? Am I a serial child murderer and don't know about it?"
I can understand that it upsets her - she likes Other People's Children a lot more than I do even if she's never been within a hundred miles of anyone they knew - but am I supposed to understand the demented?

Well, you're a developer, right? Dealing with clients, right? 
Anything that is unrelated to elephants is irrelephant
