The Power of Zero-Trust Architecture: Building a Secure Internal Network with Nebula

Imagine if we could establish a level of trust that in our network, we can verify with certainty that a computer really is who it says it is! By bringing mutual authentication and trust into networking, we can better make security decisions on when connections should be allowed. This can enable our services to talk to each other securely over the global internet, and reduce the dependence on a a trusted perimeter. This mututal trust is the foundation of a zero-trust security model. In this video, I'm going to walk through the basics of zero-trust security, the choices I've made to implement it in my own network. One of those choies is Nebula, an open-source zero trust overlay network designed for highly scalable distributed networks. Come along on this adventure!
