The Addressing Visibility Challenges with TLS 1.3 project builds on the NCCoE's earlier work, TLS Server Certificate Management, which showed organizations how to centrally monitor and manage their TLS certificates. We are now focusing on protocol enhancements such as TLS 1.3 which have helped organizations boost performance and address security concerns. These same enhancements have also reduced enterprise visibility into internal traffic flows within the organizations' environment. This project aims to change that—and has two main objectives:

  • Provide security and IT professionals practical approaches and tools to help them gain more visibility into the information being exchanged on their organizations’ servers.
  • Help users fully adopt TLS 1.3 in their private data centers and in hybrid cloud environments—while maintaining regulatory compliance, security, and operations.

This project will result in a publicly available NIST Cybersecurity Practice Guide in the Special Publication 1800 series, which contains practical steps and guidance to implement our cybersecurity reference designs.
