- A
Exposed S3 bucket
Why wrong: Exposed bucket is about public access, not IAM roles.
- B
Over-permissive IAM
Wildcard permissions like 's3:*' grant too broad access.
- C
Insecure API endpoint
Why wrong: This relates to API security, not IAM policy scope.
- D
Hardcoded credentials
Why wrong: Hardcoded credentials are secrets in code, not IAM policies.

CCSP Cloud Application Security Practice Question
This CCSP practice question tests your understanding of cloud application security. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 cloud application uses an IAM role with a policy that allows 's3:*' on all buckets. This is an example of which cloud security issue?
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
✓
Over-permissive IAM
Over-permissive IAM roles with wildcard permissions grant excessive privileges, violating least privilege.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Exposed S3 bucket
Why it's wrong here
Exposed bucket is about public access, not IAM roles.
- ✓
Over-permissive IAM
Why this is correct
Wildcard permissions like 's3:*' grant too broad access.
Related concept
Authentication checks who the user is.
- ✗
Insecure API endpoint
Why it's wrong here
This relates to API security, not IAM policy scope.
- ✗
Hardcoded credentials
Why it's wrong here
Hardcoded credentials are secrets in code, not IAM policies.
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 analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
