Dear OGF colleagues, For your information and to recruit your input, the US NIST Draft document SP 800-223 provides guidance on standardizing and facilitating the sharing of HPC security postures by introducing a zone-based HPC system reference model that captures common features of HPC systems and serves as a foundation for a system lexicon. The draft also discusses HPC system threat analysis, security postures, challenges, and recommendations. https://csrc.nist.gov/publications/detail/sp/800-223/draft The public comment period for this initial public draft is open through April 7, 2022. Additional information can be found at the NIST HPC Security Working Group website.<https://csrc.nist.gov/Projects/high-performance-computing-security> Another related workshop on multi-cloud technologies and zero-trust architectures will be held May 22-24, 2023 (separate from the workshop held last month for the HPC effort mentioned above but addressing similar concepts and themes). A short summary from the web site for this event is included below. The link to this announcement is https://www.nist.gov/news-events/events/2023/05/4th-multi-cloud-conference-a... The conference program features both leadership and actionable insight from experts in service mesh, ZTA, identity-centric security, open-source software development, and emerging NIST Special Publications. Presentations will cover a wide range of topics, including: * NIST recommendations for realizing zero trust principles in cloud-native applications and for securing artifacts in software supply chains * Approaches for authentication and access control for users, services, and devices in cloud-native applications in multi-cloud environments * The role of open source in cloud-native application security and compliance * Best practices and common pitfalls for implementing ZTA Policymakers, entrepreneurs, students, and cybersecurity professionals are encouraged to attend. Questions should be directed to the conference organizers.
