Deploying Kubernetes Without Scaring Off Your Security Team [I] - Paul CzarkowskI, Pivotal & Major Hayden, Rackspace
subtitle: "The Major Hayden Center For Kubernauts Who Can't Security Good And Wanna Learn To Do Other Stuff Good Too"

One of the larger roadblocks we face in the enterprise when trying to adopt new technologies is getting the security and compliance teams onboard.

Tools like kubicorn and kubeadm are likely the foundation on which Kubernetes deployments will be performed in the future as they help simplify the deployment and operations of Kubernetes a very complex distributed system.

However concerns about security and compliance, which are not as yet addressed by those tools, may act as inhibitors and road blocks to using these them and thus Kubernetes in the enterprise.

Thankfully the techniques and tools for deploying Enterprise Linux distributions, securing them, and ensuring compliance already exist and can be very easily combined with kubernetes.

In this talk we’ll expand upon these enterprise requirements and use cases and show how we can use existing Ansible tooling to deploy kubernetes on bare metal or the cloud, monitor it with common enterprise monitoring tools, secure it with a 2fa SSH bastion, and ensure [DISA STIG] compliance.

Preventing Attacks at Scale [I] - Dino Dai Zovi, Capsule8

Security hardening for containers, clusters, and operating systems is a very important part of setting up infrastructure and always "Plan A". The world of "Plan A" defends the importance of making sure your cluster is set up securly. Dino comes from the world of "Plan B" and will focus on detecting when security boundaries have been breached. This is necessary for environments where you don't have ability to ensure base OS is fully patched, etc.

Step into the world of Linux kernel features such as seccomp, eBPF, kprobes and Kubernetes tunable security features and learn how to detect and defend against attacks at scale.

Certifik8s: All You Need to Know About Certificates in Kubernetes [I] - Alexander Brand, Apprenda
Certificates are an integral part of a secure Kubernetes cluster deployment. They are mainly used to secure the Kubernetes API server using TLS, but certificates (and keys) are also used for other cluster functions such as client authentication, encryption of secrets, TLS bootstrapping, and the generation of service account tokens.

Certificates pose interesting challenges to cluster operators. What does the certificate setup look like in an ideal scenario? How long should certificates be valid for? When nearing expiration dates, how can certificates be rotated to ensure the cluster remains operational? These challenges must be understood when it comes to deploying and operating a Kubernetes cluster.

After this talk, you should have a better understanding of:
- How each cluster component uses certificates for secure communications
- How certificates can be used for authentication, including service account tokens
- How the Kubelet TLS bootstrapping process works
- How to plan, generate and deploy the certificates required for a secure cluster
- How to rotate certificates that are nearing their expiration date

Vault and Secret Management in Kubernetes [I] - Armon Dadgar, HashiCorp
Secret data is everywhere, from database credentials, TLS certificates, API tokens, to encryption keys. Manageing secrets is a difficult challenge, but HashiCorp Vault provides an answer. In this talk, we discuss the challenges in secret management, provide an overview of Vault, and discuss how Vault and Kubernetes can be integrated. Integrating Vault solves the basic secret management challenge of securely distributing credentials, but also gives applications running Kubernetes access to features like dynamic secrets which are generated on demand and cryptographic offload to securely manage data in transit and at rest.

Compliance and Identity Management in Kubernetes [I] - Marc Boorshtein, Tremolo Security, Inc.
Compliance with what? Depends on your industry. As k8s continues to expand into regulated enterprises such as government, health care and financials deployments will need to understand how managing users and their access relates to compliance obligations. This session will focus on how identity management can be approached for solving this issue. How do you onboard users? Authorize their access to a namespace? Offboard them? Is there a need to differentiate between a privileged user and an unprivileged user? I'll go beyond the technical implementation in k8s and tie it to specific compliance requirements in FISMA and demo how solving the compliance issue can also improve the usability and security of your k8s deployment. This talk will follow a similar form to https://www.tremolosecurity.com/openshift-compliance-and-identity-management/ but specifically on k8s.

Multi-Tenancy Support & Security Modeling with RBAC and Namespaces [I] - Fred Vong & Michael Y. Chen, VMware
As container technologies mature, Kubernetes is clearly gaining momentum with developers as a means to deploy their distributed applications. As more applications and clusters are deployed by more developers, multi-tenancy and isolation become concerns not only for the app developer, but also for the cluster admins. In this talk, we will discuss the various cluster security models available today, and how to use namespaces to provide tenant isolation. We will also demonstrate how to use Kubernetes’ Role Based Access Control (RBAC) feature as means of enforcing a multi-tenant security model. By assigning roles and role bindings and creating namespaces, we can implement restrictions on resource consumption and provide tenant isolation throughout the cluster. We’ll also demonstrate how the RBAC feature provides granularity of access control that can be adjusted to suit varying requirements—from granting full access to users or groups to a cluster to only granting access to specific resources within a namespace. Following the discussion of how to build a security model with namespaces and RBAC, this talk will also feature a live demonstration of RBAC and namespaces in action to illustrate the concepts and show how both admins and developers are affected by the model.

Shipping in Pirate-Infested Waters: Practical Attack and Defense in Kubernetes [A] - Greg Castle & CJ Cullen, Google
Kubernetes has a growing array of security controls available, but knowing where they all fit in, what the highest priorities are, and how it all helps against real attacks is still far from obvious. In this talk we’ll take a vulnerable application, exploit it, install tools, escalate privileges, propagate between containers and gain control of the cluster. At each stage of the attack we’ll demonstrate how proactive steps could have prevented these actions (or at least made them more difficult), from the container build process to writing RBAC/PodSecurity/AppArmor/Network policies, and more. Since configuration of each defence could be the subject of it’s own deep-dive talk, we’ll mainly focus on the big picture of “what” technologies you’d use to configure your cluster securely and “why”.

Enforcing Bespoke Policies in Kubernetes [I] - Torin Sandall, Styra
Kubernetes enables fully-automated, self-service management of large-scale, heterogenous deployments. These deployments are often managed by distributed engineering teams that have unique requirements for how the platform treats their workloads, but at the same time, they must conform to organization-wide constraints around cost, security, and performance. As Kubernetes matures, extensibility has become a critical feature that organizations can leverage to enforce their organization’s bespoke policies.

In this talk, Torin explains how to use extensibility features in Kubernetes (e.g., External Admission Control) to enforce custom policies over workloads. The talk shows how to build custom admission controllers using Initializers and Webhooks, and shows how the same features lay the groundwork for policy-based control through integration with third party policy engines like the Open Policy Agent project.

Hacking and Hardening Kubernetes Clusters by Example [I] - Brad Geesaman, Symantec
While Kubernetes offers new and exciting ways to deploy and scale container-based workloads in production, many organizations may not be aware of the security risks inherent in the out-of-the-box state of most Kubernetes installations and the common practices for deploying workloads that could lead to unintentional compromise. Join Brad Geesaman, the Cyber Skills Development team lead at Symantec, on an eye-opening journey examining real compromises and sensitive data leaks that can occur inside a Kubernetes cluster, highlighting the configurations that allowed them to succeed, applying practical applications of the latest built-in security features and policies to prevent those attacks, and providing actionable steps for future detection.

The hardening measures taken in response to the attacks demonstrated will include guidelines for improving configurations installed by common deployment tools, securing the sources of containers, implementing firewall and networking plugin policies, isolating workloads with namespaces and labels, controlling container security contexts, better handling of secrets and environment variables, limiting API server access, examining audit logs for malicious attack patterns, and more.

Securing Shopify's PaaS on GKE [I] - Jonathan Pulsifer, Shopify
Shopify has leveraged Kubernetes through Google Container Engine (GKE) to build its new cloud platform. This PaaS is currently serving the majority of the company's internal tools as well as business-critical production workloads. Moving to Kubernetes and a public cloud is no easy task, especially for a security team.

Unfortunately for us, a hosted solution does not offer all the features we've come to love in Kubernetes including NetworkPolicies, PodSecurityPolicies, and admission controllers among others. Given this, the security team has created a number of Kubernetes controllers and other cloud platform solutions to maintain an effective security posture on our new platform.

In this talk we'll introduce our cloud platform, explore the tools we've created to bridge the security gaps, detail the struggles we've encountered using Google Cloud Platform and GKE, and discuss our growing pains with Kubernetes multi-tenancy. Attendees will gain an understanding of the current state of Kubernetes security controls on GKE, a familiarity with some of the products available on Google Cloud Platform, and insight on how to integrate security controls into their development pipelines.

Real Security for Services on Kubernetes [I] - Eric Wang & Yun Zhang, Databricks
We all love the ease-of-use Kubernetes provides to engineers to deploy and manage their services. But before you can start running production code and dealing with customer data, you need to ensure that everyone's favorite features are in place: audit logs and access control. (And the crowd goes wild!)

At Databricks, we know that the best way to do security is to make sure the simplest way to do something is the secure one. In this talk, we introduce a system called Genie which uses time-boxed TLS certificates to authorize engineers to talk to certain namespaces within Kubernetes. Additionally, we will discuss how we extended this framework to allow for continuous deployment/continuous integration without weakening our security story!
