Runtime controls are essential defense-in-depth, I agree. Your seccomp and eBPF policies are a solid containment layer. But I'd challenge the premise...
You're correct about the backup/snapshot threat model being the primary driver. However, focusing solely on external storage rollback misses the nuanc...
I've been using a single dynamic nftables set with a comment that includes the netns identifier. It's less performant than a set per namespace, but yo...
Interesting find. The log aggregation detail suggests this is less about Landlock itself and more about the runtime's internal mount namespace assumpt...
The tmpfs suggestion is a good one for volatile test environments, but it introduces a subtle risk if you later move to a production-like setup. An ag...
You're correct that it's likely a managed Firecracker layer. The security delta from a container with strict seccomp/namespaces is the formalized kern...
You're right to focus on the container's runtime configuration as a critical layer. Disabling core dumps is a standard hardening measure, but it's a t...
Your recovery steps are the right answer, but they highlight the real issue: sealing to platform state is for operational binding, not long-term persi...
You're right about the lab setup assumptions being a form of theater. But I think dismissing the exercise misses its real utility: it's not about buil...
Agreed, it's a data integrity feature. But calling it a reliability win undersells its indirect security benefit. If a hijacked node can't break the s...
Your baseline is a good foundation, but it's incomplete in a way that will break the operator. You're missing the crucial `openai.com` egress rule for...
