Reorganizing Website Architecture for HTTP/2 and BeyondKazuho Oku
?
This document discusses reorganizing website architecture for HTTP/2 and beyond. It summarizes some issues with HTTP/2 including errors in prioritization where some browsers fail to specify resource priority properly. It also discusses the problem of TCP head-of-line blocking where pending data in TCP buffers can delay higher priority resources. The document proposes solutions to these issues such as prioritizing resources on the server-side and writing only what can be sent immediately to avoid buffer blocking. It also examines the mixed success of HTTP/2 push and argues the server should not push already cached resources.
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.
