<p><b>New page</b></p><div>'''ATM Linux''' (Advanced Transaction Management Linux) is a **highly hardened, minimal server distribution** based on **Alpine Linux** designed exclusively for **financial transaction and point-of-sale (POS) systems**.<br />
<br />
== Base and Philosophy ==<br />
<br />
* '''Base Distribution:''' Based on **Alpine Linux**, chosen for its extremely small footprint, security focus (musl libc), and transactional filesystem capabilities, which are ideal for dedicated appliance-like systems.<br />
* '''Goal:''' To provide an ultra-secure, tamper-proof operating system core for devices that handle sensitive financial data, such as Automated Teller Machines (ATMs) and retail POS terminals.<br />
<br />
== Core Features ==<br />
<br />
* '''Security Hardening:''' The system is stripped of all unnecessary services and features, uses mandatory access control, and is frequently deployed with an **immutable root filesystem** to prevent tampering and malicious code injection.<br />
* '''Financial Protocol Support:''' Includes libraries and support for common financial protocols (e.g., ISO 8583) and hardware interfaces for card readers, printers, and secure pin-pads.<br />
* '''Minimal GUI/Headless:''' Typically runs entirely headless or with an extremely minimal graphical shell that is locked down to only run the single transaction application, ensuring minimal attack surface.<br />
* '''Target User:''' Financial institutions, retail technology providers, and developers building secure, dedicated embedded systems for handling money and sensitive customer information.</div>Shaunak Chakraborty
