Alpine Linux is a community developed operating system designed for routers, firewalls, VPNs, VoIP boxes, containers, and servers. It was designed with security in mind; it has proactive security features like PaX and SSP that prevent security holes in the software to be exploited. The C library used is musl and the base tools are all in BusyBox. Those are normally found in embedded systems and are smaller than the tools found in GNU/Linux systems.
