engines, such as Wind River ® Simics ® . Simics lets you decouple your work from physical hardware, while still retaining the abil- ity to connect physical hardware when required. Simics virtual hardware gives you on-demand access to any target system, supporting continuous integration and automated testing with members of your development team, or even suppliers. Simics uses virtual hardware to conduct full-system simulations, which is often the only way to detect cybersecurity threats that originate with one component attacking others. The advantages of this approach are: Simics goes beyond simulating processors and boards; it assembles complete networked systems running the full produc- tion software stack runs. As noted earlier, these are unmodified binaries, including BIOS, firmware, operating systems, and applications. Recent Simics releases improve multi-core and parallel core support. Fully parallel simulation is on the horizon, and today Simics provides support for distributing complex, multi-core simulations across available host resources. The only restriction on the complexity of the system or its performance requirements is the capacity of the simulation host network. And despite its simulation focus, you can still use pass-through technology to connect physical hardware via standard inter- faces, such as Ethernet, I2C, PCI, SCSI, serial, and USB. Regression testing is an important part of verifying security fixes. Simics isn't new to the full-system regression testing role. It's been successfully employed by the largest system integrators to ensure platform reliability. For example, NASA's Independent Test Capability Team uses Simics in its NASA Operational Simulator (NOS), which models complete spacecraft missions in real time to verify flight-ready software and hardware. 4 Make Simics Your Next Step in Cybersecurity Defense With cybersecurity threats exploding for embedded systems, now is the time to begin pen testing your mixed-criticality sys- tems. Because Simics can simulate systems from tiny stand-alone modules up through complete systems running complex missions, it should be part of your security testing tool kit. About Sean Evoy As the product manager for Wind River Simics and Wind River Workbench, Sean Evoy is responsible for bringing new product and solution innovation to market to assist customers with their most complex development lifecycle problems. The tools portfolio addresses customers across all Wind River market segments, including aerospace and defense, cybersecurity, industrial automation, utilities, and transportation.

You can conduct tests not possible on physical hard- ware, such as spoofing malware to trigger a response that exposes its existence. 2. Developers can test defense-in-depth strategies, such as flagging a suspect component as inoperable, isolating it from the system. 3. Simics can act as a cybersecurity "sandbox," safely containing suspect malware for forensic analysis. Wind River is a global leader of software for the intelligent edge. Its technology has been powering the safest, most secure devices since 1981 and is in billions of products. Wind River is accelerating the digital transformation of mission-critical intelligent systems that demand the highest levels of security, safety, and reliability. © 2021 Wind River Systems, Inc.
