Summary : Specific purpose devices, such as wireless access points and firewalls, are everywhere and provide the most different functionalities with a wide variety of hardware/software configurations. There are lots of work related to hardening techniques, but they usually focus on general purpose systems. This presentation will discuss important points related to operating system security for specific purpose systems.
Among the topics are boot sequence modifications to improve the authenticity of the software in execution, kernel modifications to turn exploitation attempts into a non-reliable task and cryptography mechanisms to help protecting information. The concepts behind each of the discussed point will be explained and illustrated with Linux. The speaker experience in real-life systems with very specific hardware security design will also be shared.
