- A
Overly permissive RBAC configurations
Excessive permissions in Kubernetes can lead to privilege escalation or unauthorized access.
- B
Keeping container images up to date
Why wrong: This is a security best practice, not a misconfiguration.
- C
Running containers with the 'privileged' flag
Privileged containers have full access to the host, posing a security risk.
- D
Implementing network policies to restrict pod communication
Why wrong: Network policies are a security control to limit traffic, not a misconfiguration.
- E
Using hostPath mounts
HostPath mounts can allow a container to access sensitive host files.

CS0-003 Vulnerability Management Practice Question
This CS0-003 practice question tests your understanding of vulnerability management. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Overly permissive RBAC configurations

Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
Quick reference
Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| 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 |
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related CS0-003 questions on access control and AAA configuration.
