Linux as operating system in ATM, why no suggestions?

Question

linux

Good afternoon, as you know, support for the XP version for ATMs will soon expire, and banks will have to upgrade to at least 7k, and these are additional costs. I'm wondering why there are no market (no benefits?) offers to move from Windows to Linux to ATM?

Answer 1

Likewise with why in an office environment everyone sits in Windows. Indeed, for ATM banks, it is not much different from ordinary user PCs from an administrative point of view.
And the reason for this is simple: there is no software for the necessary needs, there is no necessary technical support, there are no qualified personnel, and indeed there is no need at all.
If you're complaining about a Windows support bill, answer the question of how long it took to support and update Windows XP, how long did the same procedures take for any release of Ubuntu.

Answer 2

first and foremost - drivers. Under Windows they are, under Linux they are not.
plus support for Linux is exactly also not infinite.
By the way - there were some ATMs from Belarusians (?) with Linux on board.

Answer 3

An erroneous judgment about the lack of linux-based solutions for ATMs. It's just that they're not that common, due to several factors.
It is possible that the end of support for Windos XP will push the market to look for new platforms and dilute the choice of OS for ATMs.
Not for the sake of advertising, it will be said, but for example, Soft Logic has a solution based on Centos with client software and not only for ATMs.

You haven’t bought a car for your mistress yet from the technical director, but you want to deprive him of kickbacks?

Answer 5

And still there were ATMs with a semiaxle! there is no support here for 10 years, but they work :-)
Often such devices do not need support. I suspect that the payback of the ATM is about a year. for 3-5 years you can just put a new one! So the process is comparable to the old servers - they are simply replaced! I worked out my own - to the scrap, the new one will be with a new OS, and there is no need to update anything.
Well, yes, there will be a zoo of operating systems, but this is a small problem, especially since the cost of the OS itself, God forbid, will be 1% of the cost of an ATM (this is probably an OEM all cropped and embedded, it will be about $ 22 per device).
And here:

Windows Embedded 8.1 Industry, like the rest of the products in the Embedded channel, has a 15-year life cycle. This allows you to create solutions for the long term, without worrying that a new operating system has come out and the previous one is no longer available.

Answer 6

Does anyone update ATMs?
Here, as with the VAZ - MS has honed its axis so much that it does not need updates, just use it.
And linux, as always, has troubles with support and firewood. If you pick up iron, then I see no reason not to use linux. I once made kiosks, but everything is simpler there.

Answer 7

Properly configured Windows XP is not so critically vulnerable due to the small attack area. Connections to ATM over the network are excluded at the level of network equipment and configured policies that allow connections from a limited list of IP addresses. The launch of the software is also limited by the white list, everything that is not in it is blocked. Doing anything more serious without connecting a keyboard or mouse will not work, and access to the inside of the ATM is controlled and limited.
Those. when hacking an ATM, there are 2 scenarios:
1) Gaining network access - i.e. hacking the bank's network and connecting from internal resources, or physically switching ATM to your network equipment (again, physical access).
2) Physical access to ATM - if an attacker is standing next to an ATM and can connect to his PC, it doesn’t matter what OS it is on. with 99% probability they will launch a pre-prepared LiveCD.
I recommend reading the article . Everything, as usual, rests on the support of hardware and software.
It is expensive for device manufacturers to support an XFS software stack for Windows and Linux at the same time, and given that 99% of ATMs run on Windows, the choice of a supported platform is obvious.
Same with software. If the hardware is not supported, then compatibility with Linux is checked only at the request of specific banks, and not for free.
So it turns out that in order to switch to Linux, a bank needs to develop everything from scratch and check the performance of the entire system. Checking the work on real hardware in battle is again a risk - you can give out more money than you need, or less. Customer dissatisfaction and the analysis of each disputed transaction is very expensive for the bank. Plus, besides, you need to retrain the entire staff, or recruit new ones who also need to be trained.
Therefore, the conclusion is simple: "It works - do not touch it."
