Questions and topics: (please feel free to update or make
comments for clarifications)
* Kubernetes vs. Docker vs. LXC vs. VMs - why did you settle on
K8s?
* What’s new with k8s? Version 1.33? Do you always implement the
latest version in your CTF, or something that is deliberately
vulnerable? (https://www.loft.sh/blog/kubernetes-v-1-33-key-features-updates-and-what-you-need-to-know)
* When you are making a CTF, what’s your methodology? Threat model
then verify? Code review? Github pull requests?
* Story time; Not the first year you’ve done this(?), have
participants ever surprised you finding something you didn’t
expect?
* If I’m running K8s at my workplace, what should be bare minimum
k8s security I should implement? Any security controls that I
should implement that might cause performance or are ‘nice-to-have’
but may run counter to how orgs use k8s that I should be concerned
about implementing?
