Exploring WebAssembly and Kubernetes Security Conversations

Cross-over hosts:

• Kaslin Fields, co-host at Kubernetes Podcast

• Abdel Sghiouar, co-host at Kubernetes Podcast

Guest:

• Michele Chubirka, Cloud Security Advocate, Google Cloud

Topics:

• How would you approach answering the question ”what is more secure, container or a virtual machine (VM)?”
• Could you elaborate on the real-world implications of this for security, and perhaps provide some examples of when one might be a more suitable choice than the other?
• While containers boast a smaller attack surface (what about the orchestrator though?), VMs present a full operating system. How should organizations weigh these factors against each other?
• The speed of patching and updates is a clear advantage of containers. How significant is this in the context of today's rapidly evolving threat landscape? Are there any strategies organizations can employ to mitigate the slower update cycles associated with VMs?
• Both containers and VMs can be susceptible to misconfigurations, but container orchestration systems introduce another layer of complexity. How can organizations address this complexity and minimize the risk of misconfigurations leading to security vulnerabilities?
• What about combining containers and VMs. Can you provide some concrete examples of how this might be implemented? What benefits can organizations expect from such an approach, and what challenges might they face?
• How do you envision the security landscape for containers and VMs evolving in the coming years? Are there any emerging trends or technologies that could significantly impact the way we approach security for these two technologies?
