Here's a potential description for the talk "Implementing Zero Trust for Hybrid and Multi-Cloud Kubernetes Deployments":
As organizations increasingly adopt Kubernetes across hybrid and multi-cloud environments, ensuring consistent security controls and zero-trust principles can be a daunting challenge. Different clusters, clouds, and on-prem infrastructure each introduce unique security considerations and complexities. How can we effectively implement zero-trust security in these heterogeneous environments?
In this talk, we'll explore the key security challenges of hybrid and multi-cloud Kubernetes deployments and discuss best practices for implementing consistent zero-trust controls across diverse infrastructures.

Highlight various open source tools and technologies, such as Istio, Cilium, Open Policy Agent, Kubernetes Federation, and multi-cluster management platforms like Rancher and Anthos, that can help address these challenges.
