  5. 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.

  6. 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

  11. ● 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

  18. @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…

  21. @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 🚀

  24. ✅ 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 ✈
