Linux operating system was implemented on top of L4. As mentioned, work has been done in the area of hardware support of real-time systems and the microkernel real-time operating system structure ...

seL4, a secure microkernel used in UAV systems, is open source, which may bolster critical infrastructure, embedded medical devices, and connected cars security ...

I should start by voicing my great irritation toward the version meme applied to the commercial operating systems: v6 now allows you to do this instead of that, how wonderful. Except, doing this ...

The idea behind the microkernel is that the kernel, or most privileged parts of the operating system, should be stripped down only to those parts that really require such access.

HelenOS is a microkernel-based OS aiming to be a research vehicle for operating system design. Aesthetically, HelenOS resembles Windows 3.1 and 95 with nostalgic appeal. HelenOS is in early stages ...

Also: The Linux file system structure explained Not with its looks. Redox OS is fairly average-looking. Not with the amount of pre-installed apps. Redox OS only includes a handful of apps.

Want a truly secure operating system kernel? The Linux Foundation is partnering with Australia's national science agency, CSIRO, to roll out the seL4 microkernel.

Even on a least privilege OS, processes are at the mercy of both the integrity of the microkernel and OS system policies, making it difficult to prove that the applications are truly separate.

But in a microkernel-based system, the driver would run as a user-level server in its own address space. “As such, [it] could not overwrite kernel memory and cause a system crash, information ...

With a microkernel, almost everything that used to be a system call now falls under the heading "passing a message to another process". In this case, flipping a supervisor bit is no longer enough to ...
