Adopting Network Policies for Multi-Tenant Environments - Raymond de Jong

This talk addresses the importance of securing Kubernetes networking, which is open by default, and emphasizes the need for implementing network policies. The speaker, Raymond de Jong, introduces the fundamentals of Cilium Network Policies, covering application-aware and identity-based security. He explains the differences between default-allow and default-deny policies and advocates for a risk-based approach to protect sensitive workloads. The session also explores how observability tools such as Cilium, Hubble, and Grafana can enhance network policy management and configuration, empowering attendees to secure their networks effectively in multi-tenant environments.
