  • Advanced Search for Engineering Design Patterns, allowing users to pre-select keywords and filters to quickly and easily find design patterns for their engineering needs
  • A Recently Viewed Assets feature and Search and Resource Suggestions to simplify the resource discovery process and provide easier access to previously viewed resources
  • A Refined Algorithm that improves the overall rating detail to better reflect resource quality and relevance
  • New Guest Prompts that streamline the process for new users and encourages them to register to take full advantage of the personalized features or nominate content to be added to the CRWS-BoK repository
  • Added Reports Storage and Search capability, and updated metrics tracking

“Version 4.0 is designed to improve the user experience, allowing for greater user engagment with the tools, content, and features in CRWS-BoK,” said SysSec director Melinda Reed. “This update enhances the user’s ability to discover and learn more about cyber resilience, the ultimate goal of CRWS-BoK.

“The new features facilitate improved user involvement and engagment with the platform, from selecting a theme color to personalizing their viewing options. Additionally, they can perform Advanced Searches for Engineering Design Patterns or nominate new resources, which will help create a more robust. We will continue to refine the user experience so that the CRWS-BoK remains an essential resource for our SSE and S&T workforces.”

R&E partners with SSE and S&T professionals through the SysSec Directorate to foster assured resilient missions, systems, and components. It leverages best practices and promotes innovation enabing the nation’s SSE and S&T workforce to engineer CRWS that can successfully operate in the face of persistent cyber threats.
