The VxWorks® MILS Platform 2.x Essentials training workshop provides engineers with a fast, cost-effective way to acquire the skills necessary to deliver the security foundation that meets real-time operating system (RTOS) requirements for High Robustness (EAL6+) multilevel secure (MLS) systems.

After this course, participants will be able to perform the following:

  • Describe the Common Criteria, Multiple Independent Levels of Security (MILS) architecture, and high assurance security principles
  • Explain how Wind River® VxWorks MILS Platform 2.x and high assurance security standards form the basis of a security-certified partitioned system, including networking support, XML configuration, and debugging
  • Accelerate the configuration, development, and deployment of MILS systems using the built-in XML development tools and Wind River Workbench
  • Configure, debug, build, and test secure MILS applications with VxWorks MILS Platform 2.x.
  • Wind River VxWorks MILS Platform 2.1
  • Application developers utilizing the MILS architecture to create secure applications
  • Those who will develop applications using the VxWorks MILS kernel
