Harden a Linux Container Runtime Against Privilege Escalation
Overview
What this challenge is about.
Harden a Linux Container Runtime Against Privilege Escalation. Advanced challenge in code. Writing production code that solves real engineering problems, ear...
The Brief
What you'll do, and what you'll demonstrate.
Re-baseline and harden a Kubernetes worker-node OS posture, deploy runtime detection, and prove the documented attack chain is now blocked.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Baseline OS posture with kube-bench, Trivy, and OSCAP
- Write workload-class AppArmor profiles that don't break the app
- Deploy runtime detection (Falco) with high-signal rules
- Validate hardening against a known attack chain end-to-end
