The US Defense Advanced Projects Agency (DARPA) ran a “Cyber Grand Challenge” in 2016, where automated cyber-attack and cyber-defense systems were pitted against each other to drive progress in autonomous cyber-security. The competition was run on physical computers (obviously), but Simics was used in a parallel flow to check that competitors’ programs were not trying to undermine the infrastructure of the competition rather than compete fairly inside the rules of the competition.
This “vetting” system was explained in a paper from 2018, and I have a blog post up on my Intel Blog about how Simics was used. Overall, the system that was built was very impressive – following the execution of software in a detailed manner to detect if it was trying to break out of the operating system sandbox in which it ran.
The researchers also connected Simics to the HexRays* IDA Pro* Debugger, including the enabling of Simics reverse execution from IDA. It is an excellent example of what you can do given extensible and programmable platforms like Simics (and IDA). In the presentation, the researchers end with a nice slide about “Bring Your Own Simics” 🙂
I love bug and debug stories in general. Bugs are a fun and interesting part of software engineering, programming, and systems development. Stories that involve running Simics on Simics to find bugs are a particular category that is fascinating, as it shows how to apply serious software technology to solve problems related to said serious software technology. On the Intel Software and Services blog, I just posted a story about just that: debugging a Linux kernel bug provoked by Simics, by running Simics on a small network of machines inside of Simics. See https://blogs.intel.com/evangelists/2016/05/30/finding-kernel-1-2-3-bug-running-wind-river-simics-simics/ for the full story.
Looks like S4D (and the co-located FDL) is becoming my most regular conference. S4D is a very interactive event. With some 20 to 30 people in the room, many of them also presenting papers at the conference, it turns into a workshop at its best. There were plenty of discussion going on during sessions and the breaks, and I think we all got new insights and ideas.
