Show: 14Show Overview: Brian and Tyler talk address some of the many layers of security required in a container environment. This show will be part of a series on container and Kubernetes security. They look at security requirement in the Container Host, Container Content, Container Registry, and Software Build Processes.   Show Notes and News:10 Layers of Container SecurityGoogle, VMware and Pivotal announced a Hybrid Cloud partnership with KubernetesGoogle and Cisco announced a Hybrid Cloud partnership with Kubernetes (and more)Docker adds support for Kubernetes to DockerEERancher makes Kubernetes the primary orchestratorMicrosoft announces new Azure Container Service, AKSOracle announced Kubernetes on Oracle Linux (and some installers)Heptio announces new toolsTopic 1 - Let’s start at the bottom of the stack with the security needed on a container host.Linux namespaces - isolation Linux capabilities and SECCOMP - restrict routes, ports, limiting process calls SELinux (or AppArmor) - mandatory access controls cGroups - resource managementTopic 2 - Next in the stack, or outside the stack, is the sources of container content.Trusted sources (known registries vs. public registries (e.g. DockerHub) Scanning the content of containers Managing the versions, patches of container contentTopic 3 - Once we have the content (applications), we need a secure place to store and access it - container registries.Making a registry highly-available Who manages and audits the registry? How to scan container within a container? How to cryptographically sign images? Identifying known registries Process for managing the content in a registry (tagging, versioning/naming, etc) Automated policies (patch management, getting new content, etc.) Topic 4 - Once we have secure content (building blocks) and a secure place to store the container images, we need to think about a secure supply chain of the software - the build process.Does a platform require containers, or can it accept code? Can it manage secure builds? How to build automated triggers for builds? How to audit those triggers (webhooks, etc.)? How to validate / scan / test code at different stages of a pipeline? (static analysis, dynamic analysis, etc.) How to promote images to a platform? (automated, manual promotion, etc.)Feedback?Email: PodCTL at gmail dot comTwitter: @PodCTL Web: http://podctl.com
