Mastering Kubernetes Security with Kubernetes Goat - Cloud-Native Modernization @ TechTarget

Mastering Kubernetes Security with Kubernetes Goat - Cloud-Native Modernization @ TechTarget

Kubernetes security is crucial in ensuring the safety and integrity of your organization's data and systems. However, keeping up with the latest security threats and vulnerabilities can be a daunting task. This is where Kubernetes Goat comes in - a "vulnerable by design" Kubernetes Cluster environment that allows you to practice and learn Kubernetes security in a hands-on way.

In this webinar, Pragmatic Security Leader Madhu Akula presents the latest version of Kubernetes Goat and demonstrates how to use it to identify and mitigate vulnerabilities in Kubernetes and containerized environments. He will cover various attack scenarios and real-world vulnerabilities and show how Kubernetes Goat scenarios can be mapped with them. The session will also explore open-source security tools that can be used to write secure code and deploy secure containers in production.

Key Takeaways:
- Gain practical, hands-on experience with Kubernetes security through 25+ offensive and defensive scenarios.
- Learn about the latest security threats and vulnerabilities in containers, Kubernetes, and cloud-native environments.
- Access detailed documentation, labs, and other resources to continue your learning and development in Kubernetes security.
- And more...

About Me 😊 @madhuakula
  2. What is Docker? • Docker is an open source platform

    for building, deploying, and managing containerized applications • Docker became the de facto standard to build and share containerized apps - from desktop, to the cloud, even edge devices • Docker enables developers to easily pack, ship, and run any application as a lightweight, portable, self-sufficient container, which can run virtually anywhere https://docs.docker.com/get-started/overview/ @madhuakula
  3. What is Kubernetes? Kubernetes is a portable, extensible, open-source platform

    for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely available. https://kubernetes.io/docs/concepts/overview/what-is-kubernetes/ @madhuakula
  4. 📚 Kubernetes Security Learning - Application Security @madhuakula The security

    of the application code and dependencies that run inside the Kubernetes cluster. This can be achieved by following secure software development lifecycle standards and conducting regular code reviews, penetration testing, and vulnerability assessments.
  5. 📚 Kubernetes Security Learning - Image Security @madhuakula The security

    of the images used to deploy containers in the Kubernetes cluster. This includes scanning images for vulnerabilities, using image signing and verification, and only using trusted sources for images.
  6. 📚 Kubernetes Security Learning - Supply-chain Security @madhuakula The security

    of the entire process from writing application code to deploying it in production, which involves areas such as libraries, dependencies, signing, SBOM, validation, and enforcement with the SLSA framework.
  7. 📚 Kubernetes Security Learning - Infrastructure Security @madhuakula The security

    of the underlying infrastructure that supports the Kubernetes cluster, including network security, access control, and ensuring that the underlying operating system is patched and up-to-date.
  8. 📚 Kubernetes Security Learning - Container Security @madhuakula The security

    of the containers deployed in the Kubernetes cluster, including setting resource limits, using security contexts, and ensuring that containers run as non-root users.
  9. 📚 Kubernetes Security Learning - Cluster Security @madhuakula The security

    of the Kubernetes cluster itself, including securing the Kubernetes API server, etcd, and worker nodes. This can be achieved through measures such as enabling RBAC, enabling network policies, disabling anonymous access to the API server, and more.
  10. 📚 Kubernetes Security Learning - Network Security @madhuakula The security

    of the network traffic that flows in and out of the Kubernetes cluster, including measures such as network policies, encryption, and firewalls.
  11. 📚 Kubernetes Security Learning - Runtime Security @madhuakula The ongoing

    security of the Kubernetes cluster for detecting and responding to any security incidents or suspicious activity. This can be achieved through measures such as logging and monitoring, threat detection and response, and using security-focused tools like Kubernetes Goat to simulate attacks and identify vulnerabilities.
  12. 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
