TRACK: DEVSECOPS 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

TRACK: DEVSECOPS 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

TRACK: DEVSECOPS 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

Secure network boundaries using NSP Scenarios in Kubernetes Goat 🚀 15+ more scenarios releasing soon… ❤ Scenarios going to be updated with defenders, developers, tools & vendor sections for reach scenario 🥳 @madhuakula

TRACK: DEVSECOPS 🚀 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) - Coming soon 👀 ☸ Digital Ocean, Vagrant, Many others… ⚙ How can I setup Kubernetes Goat @madhuakula

TRACK: DEVSECOPS ● 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 http://127.0.0.1:1234 @madhuakula

TRACK: DEVSECOPS @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…

TRACK: DEVSECOPS @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 🚀

TRACK: DEVSECOPS ☸ 🐐 Demo Time 🤞 🙏 @madhuakula

TRACK: DEVSECOPS 🚀 Key Takeaways @madhuakula ✅ 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 ✈
