Explore the lessons learned from building a BeyondCorp-inspired SSH proxy in this 43-minute LASCON conference talk. Delve into the implementation of a zero-trust security model that authenticates and authorizes users and devices before granting access to services, eliminating the need for traditional VPN solutions. Discover how this approach extends beyond SSH, covering topics such as Chrome Secure Shell, WebSockets, server implementation using CycloneHTTP, SSH configuration, and local proxy setup. Gain insights into handling connections, message reception, and data processing, while also examining the benefits and challenges of this security paradigm. Conclude with references and latency considerations for a comprehensive understanding of BeyondCorp-style access control.
