Timesys Discretionary Access Control (DAC) Hardening Discretionary Access Control hardening can further improve your embedded system’s security by limiting userspace access to proprietary intellectual property, exploitable binaries, and privileged information. The example permissions shown here are defaults produced during a demonstration Yocto build. In Linux, a file has the following relevant parameters (when listing a file with the “ls” command):   The post Discretionary Access Control (DAC) Hardening appeared first on Timesys from Nathan Barrett-Morrison ..read more

This article discusses the process by which your kernel’s configuration can be strengthened to protect against common security exploits. This is sometimes referred to as hardening, or specifically in this context, kernel configuration hardening. A Linux kernel configuration is a file which defines all of the enabled (or disabled) options which are compiled in to your kernel. If you have not seen one before, they generally reside in ...   ..read more
