Review Summary
This PR adds 11 course modules and 22 assessments for a Docker security hacking course. However, there are critical issues that must be fixed before merge:
Critical Issues Found
1. Quiz Content Logic Error (Blocks Merge)
All 11 module quizzes contain identical generic questions that don't match their module titles. This makes the assessments non-functional for their intended educational purpose. Each quiz must have module-specific questions that test the concepts covered in that module.
2. Security Warning Removed (Blocks Merge)
The README removed the critical security warning about intentional vulnerabilities. This warning must be restored to prevent users from accidentally deploying vulnerable systems in production environments.
Required Actions
- Replace the duplicated quiz questions in all 11 module quiz files with content specific to each module's topic
- Replace the duplicated final assessment questions in all 11 final quiz files with module-specific content
- Restore the security warning in README.md
The course module content itself appears well-structured with appropriate security examples and remediation guidance.

| 1. Which control is most specific to syscall filtering? | ||
| A) AppArmor B) SELinux C) seccomp D) cgroups | ||
| 2. Exposing Docker API without auth primarily risks: | ||
| A) slower builds B) disk usage C) full host compromise D) image pulls failing | ||
| 3. The strongest container isolation boundary is: | ||
| A) shared kernel B) VM parity C) namespace + cgroup + LSM D) Docker socket |

🛑 Logic Error: Replace generic questions with module-specific content about image tampering and supply chain security. Questions should address topics like image signing with cosign, digest pinning, registry trust, tag mutation attacks, and vulnerability scanning tools (Trivy/Grype) mentioned in the module.
| 1. Which option most directly reduces runtime breakout surface? | ||
| A) --privileged B) drop caps + seccomp + read-only C) expose 2375 D) host network | ||
| 2. Which is a reliable signal of insecure images? | ||
| A) pinned digest + signed provenance B) latest tag from unknown registry C) small image size D) alpine base |

🛑 Logic Error: Replace generic final assessment questions with module-specific content about exposed container APIs. Both questions appear identical across all final assessments. Question 1 is about runtime breakout (not API exposure), and question 2 is about insecure images (not API exposure). Questions should assess understanding of Docker daemon socket security, TLS configuration, port binding risks, and API authentication mechanisms.

🛑 Logic Error: Replace generic final assessment questions with module-specific content about container escape techniques. These questions are identical across all final assessments. Questions should assess understanding of Docker socket mounting risks, privileged container dangers, capability management, host namespace sharing, and rootless Docker.

🛑 Logic Error: Replace questions 2 and 3 with LSM-specific content. While question 1 correctly addresses syscall filtering (relevant to seccomp), questions 2 and 3 are identical to other quizzes and don't relate to Linux Security Modules. Questions should cover AppArmor profiles, SELinux contexts, MAC vs DAC, security-opt flags, and the differences between seccomp, AppArmor, and SELinux as explained in the module.

Pull request overview
Updates the repository to an editorial-review draft for the “Hands-on Docker Hacking” course by adding module and assessment markdown content, plus light repo scaffolding/documentation updates.
Changes:
- Added course module drafts under
course/modules/and quiz/final assessment drafts undercourse/quizzes/. - Simplified the root
README.mdto a short course/module list. - Added supporting repo docs (
COURSE_SUMMARY.md,tests/README.md) and a new.gitignore.

Micro-Learning Topic: Denial of service (Detected by phrase)Matched on "Denial-of-Service"The Denial of Service (DoS) attack is focused on making a resource (site, application, server) unavailable for the purpose it was designed. There are many ways to make a service unavailable for legitimate users by manipulating network packets, programming, logical, or resources handling vulnerabilities, among others.
