Abstract
A new container of a pool of containers is spawned in the operating system of the embedded networking device to execute a firewall separate from an operating system of a host device. Each of the containers is generated by a separate toolchain to include custom runtime libraries. The firewall utilizes the custom libraries rather than the host libraries, and wherein user privileges within a container is different from user privileges for the host. The new container executes a firewall instance to inspect data packets processed by the embedded networking device.
