Editing AFL Linux (section)

== Industrial Control Focus ==

The foundation of AFL Linux is a customized **RHEL (Red Hat Enterprise Linux) derivative**, chosen for its decade-long support cycle and enterprise-level stability. Crucially, the kernel is configured with **PREEMPT_RT** patches to guarantee the hard real-time performance required for complex synchronization and process control.

* '''Protocol Support:''' It ships with full, certified support for industry-standard communication protocols, including **Modbus/TCP, EtherNet/IP, and OPC Unified Architecture (OPC UA)**. This facilitates seamless integration with Programmable Logic Controllers (PLCs), sensor arrays, and human-machine interfaces (HMIs) from various vendors.
* '''System Reliability:''' AFL Linux employs a watchdog timer system and a read-only root filesystem to prevent unexpected corruption due to power fluctuations or improper shutdowns, which are common issues in industrial settings. The boot process is highly optimized for fast startup, minimizing downtime after an event.
* '''Maintenance and Security:''' Updates are rigorously tested for compatibility with industrial software and are delivered with an emphasis on security vulnerabilities specific to connected industrial environments (ICS/SCADA). Long-term support for specific kernel and driver versions is a core feature, often supporting legacy hardware for over ten years.

AFL Linux helps bridge the gap between traditional IT infrastructure and Operational Technology (OT), providing a secure and stable platform for the centralized management and monitoring of complex factory automation systems.
