IoT Devices Compliant with JC-STAR Using Linux as a Container OSTomohiro Saneyoshi
?
Security requirements for IoT devices are becoming more defined, as seen with the EU Cyber Resilience Act and Japan’s JC-STAR.
It's common for IoT devices to run Linux as their operating system. However, adopting general-purpose Linux distributions like Ubuntu or Debian, or Yocto-based Linux, presents certain difficulties. This article outlines those difficulties.
It also, it highlights the security benefits of using a Linux-based container OS and explains how to adopt it with JC-STAR, using the "Armadillo Base OS" as an example.

回転ルール: 下図を覚えさえすれば OK
z x x
y y z
x z y
普通にやるとこっち
? x が上に行くようにどんどん回転! になっちゃう
? ただし,2 つ親まで見る
– そこまで直線になってたら直線のままになるように y, x の順で回転 (上図)
– そうなってなかったら普通に x を上に行かせる回転 2 連発
