Andrew Martin

This talk details low level exploitable issues with container and Kubernetes deployments. We focus on lessons learned, and show attendees how to ensure that they do not fall victim to avoidable attacks.

Andy has made mistakes. He's seen even more. And in this talk he details the best and the worst of the container and Kubernetes security problems he's experienced, exploited, and remediated.

See how to bypass security controls, exploit insecure defaults, evade detection, and root clusters externally (and more!) in this interactive and highly technical appraisal of the container and cluster security landscape.

Kubernetes provides multiple layers of network security including the control plane, etcd, the CNI network, network policies, and - with Istio on top - the requests between applications themselves. In this talk we explore the underlying technologies on which these layers are built using approachable examples and demonstrations. Attendees can expect to gain an understanding of these implementations and the principles behind encryption, identity, and trust in Kubernetes.

• What are TLS, X.509, and mutual authentication?
• Why cloud native communication should be encrypted by default
• Kubernetes component intercommunication
• CNI and network policy for applications
• Bootstrapping identity with SPIFFE
• Mutual TLS, route rules, and destination policies in Istio
