CS0-003 Vulnerability Management Practice Question
A security analyst is reviewing a containerized application for vulnerabilities. The analyst uses a container image scanner and identifies several issues. Which THREE of the following are common container and Kubernetes misconfigurations that the analyst should prioritize? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Overly permissive RBAC configurations
Privileged containers grant excessive permissions, hostPath mounts allow host filesystem access, and overly permissive RBAC can lead to unauthorized actions. Keeping containers updated is important but not a misconfiguration, and network policies are a best practice.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Overly permissive RBAC configurations
Why this is correct
Excessive permissions in Kubernetes can lead to privilege escalation or unauthorized access.
- ✗
Keeping container images up to date
Why it's wrong here
This is a security best practice, not a misconfiguration.
- ✓
Running containers with the 'privileged' flag
Why this is correct
Privileged containers have full access to the host, posing a security risk.
- ✗
Implementing network policies to restrict pod communication
Why it's wrong here
Network policies are a security control to limit traffic, not a misconfiguration.
- ✓
Using hostPath mounts
Why this is correct
HostPath mounts can allow a container to access sensitive host files.

| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
