  1. • Pragmatic Security Leader • Creator of Kubernetes Goat, Hacker

    Container, tools.tldr.run, many other OSS projects. • Speaker & Trainer at Blackhat, DEFCON, GitHub, USENIX, OWASP, All Day DevOps, SANS, DevSecCon, CNCF, c0c0n, Nullcon, SACON, null, many others. • Author of Security Automation with Ansible2, OWASP KSTG, whitepapers, etc. • Technical reviewer (multiple books) & Review board member of multiple conferences, organizations, communities, etc. • Found security vulnerabilities in 200+ organizations and products including Google, Microsoft, AT&T, Adobe, WordPress, Ntop, etc. • Certified Kubernetes Administrator, Offensive Security Certified Professional, etc. • Never ending learner! About Me 😊 @madhuakula
  2. • Introduction and overview about Kubernetes Goat 🐐 • Why

    Kubernetes Security? ◦ Some real-world attacks, threats and examples ◦ Showcasing live hacking of attacks • Why do we need to scale Kubernetes Security? ◦ The need of scale, and importance ◦ What’s we really missing here! • What should we do & how should we go about it? ◦ Examples, patterns, core issues, etc. ◦ Education, Training, Knowledge and skill gaps • Key takeaways and learnings! • Questions & Discussions? Today’s Agenda @madhuakula
  3. What is Kubernetes Goat 🐐 Kubernetes Goat is an interactive

    Kubernetes security learning playground. Intentionally vulnerable by design scenarios to showcase the common misconfigurations, real-world vulnerabilities, and security issues in Kubernetes clusters, containers, and cloud native environments. @madhuakula
  4. Kubernetes Goat has intentionally created vulnerabilities, applications, and configurations to

    attack and gain access to your cluster and workloads. Please DO NOT run alongside your production environments and infrastructure. So we highly recommend running this in a safe and isolated environment. Kubernetes Goat is used for educational purposes only, do not test or apply these attacks on any systems without permission. Kubernetes Goat comes with absolutely no warranties, by using it you take full responsibility for all the outcomes. 🚨 Disclaimer @madhuakula
  5. Can I use from Kubernetes Goat 🤔 Kubernetes Goat is

    intended for a variety of audiences and end-users. Which includes hackers, attackers, defenders, developers, architects, DevOps teams, engineers, researchers, products, vendors, and anyone interested in learning about Kubernetes Security. Below are some of the very high-level categories of audience 💥 Attackers & Red Teams 🛡 Defenders & Blue Teams 🧰 Products & Vendors 🔐 Developers & DevOps Teams 💡 Interested in Kubernetes Security @madhuakula
  6. 12. Gaining environment information 13. DoS the memory/cpu resources 14.

    Hacker Container preview 15. Hidden in layers 16. RBAC Least Privileges Misconfiguration 17. KubeAudit - Audit Kubernetes Clusters 18. Sysdig Falco - Runtime Security Monitoring & Detection 19. Popeye - A Kubernetes Cluster Sanitizer 20. Secure network boundaries using NSP 1. Sensitive keys in codebases 2. DIND (docker-in-docker) exploitation 3. SSRF in the Kubernetes (K8S) world 4. Container escape to the host system 5. Docker CIS benchmarks analysis 6. Kubernetes CIS benchmarks analysis 7. Attacking private registry 8. NodePort exposed services 9. Helm v2 tiller to PwN the cluster - [Deprecated] 10. Analyzing crypto miner container Scenarios in Kubernetes Goat 🚀 15+ more scenarios releasing soon… ❤ Scenarios going to be updated with defenders, developers, tools & vendor sections for reach scenario 🥳 @madhuakula
  7. 🚀 Katacoda Playground - Free Online in-browser ☸ Vanilla Kubernetes

    Cluster ☁ AWS Kubernetes (EKS) ☁ GCP Kubernetes (GKE) ☁ Azure Kubernetes (AKS) ☸ Kubernetes IN Docker (KiND) ☸ Lightweight Kubernetes (K3S) ☸ Digital Ocean, Vagrant, Many others… ⚙ How can I setup Kubernetes Goat @madhuakula
  8. • Make sure you have Kubernetes cluster with cluster-admin privileges.

    Also kubectl and helm installed in your system before running the following commands to setup the Kubernetes Goat ⎈ Setting up in your Kubernetes Cluster $ git clone https://github.com/madhuakula/kubernetes-goat.git $ cd kubernetes-goat $ bash setup-kubernetes-goat.sh $ bash access-kubernetes-goat.sh • Now you can access the Kubernetes Goat by navigating to @madhuakula
  9. @madhuakula Why do we need to scale Kubernetes Security? •

    Nature of immutable infrastructure • Matching the speed of containers, infrastructure with security • Frequency of deployments and workloads • Size of the teams, deployments from both dev, ops, engineering and security • How frequently and repetitively we fix certain issues • Education, knowledge and skill gap • Maturity of the security and the alignment with stakeholders • Many others…
  10. @madhuakula What should we do & how should we go

    about it? • I think there is no single answer, approach here • Always look at the core problem and root cause and fix at that layer • Try to be self-service model by providing patterns in an actionable way • Be an helping hand for DevOps, SRE and Engineering teams rather pointing just issues ◦ Helping them to create secure and safe Helm charts, Dockerfiles, Templates, etc. ◦ Removing the blockers by being pragmatic and empathetic ◦ Eliminate the possible things early and at scale • Repeat after me: Education, Education, Education ◦ Most people don’t even understand the technology, leave about security. So educating them by teaching and practicing is the way to go 🚀
  11. ✅ Security is everyone’s responsibility (Dev, Ops, Security, Management, etc.)

    ⚠ Threat model your architecture and identify risks/threats 🙌 Follow and apply secure defaults 📚Know what you have (Inventory of assets) 🧱Adopt zero trust model (Zoning, Containment & Segmentation) 🎯Apply security at each layer (Defense in depth strategy) 🚨Follow least privilege principle 👮AuthN & AuthZ 🔐Encryption at REST & TRANSIT 🛡Proactive monitoring & Active defense 🔁Continuously analyse and apply feedback loops 👉 Crawl 🐢, Walk 🚶, Run 🏃, Fly ✈ Key Takeaways! @madhuakula
  12. 🔥 All scenarios will be updated with Defenders, Developers, Tools

    & Vendors sections 📖 Updating and maintaining the great documentation 🚀 30+ more real-world hands-on scenarios coming (more and more will come 🏃…) ☸ One-click setups, various vendor related product testbeds, many more integrations 📝 Various OSS & Vendor tools (working with security vendors to bridge the gap 👋) 💥 Heavy push towards Developers, DevOps, Architects & non-security learning experience 🏆 Go to Kubernetes Security resources for anyone (from a variety experience and skills) 🎉 Sponsors, roadmap, support, contributors, more global scope around Cloud Native 🏁 What’s next for Kubernetes Goat @madhuakula
