To increase the security of an embedded system, it is important to assure the security of the embedded Linux core in the system. Biological immune system is the core to assure the health of human body and this natural system inspire them to design the security mechanism for the Linux core. To defend the embedded Linux core against viruses and software faults, an immune computation is proposed. The embedded Linux is customized from the standard Linux by keeping the Linux core and deleting the unnecessary components. Immunization of the Linux core is designed into the process control, memory management, communication, driving programs, and file system.
