- A
Mass assignment
Why wrong: Mass assignment relates to object binding, not cloud storage configuration.
- B
SSRF vulnerability
Why wrong: SSRF involves server-side requests, not bucket policies.
- C
Exposed S3 bucket
A bucket policy granting access to all principals (Principal: *) makes the bucket publicly readable.
- D
Over-permissive IAM
Why wrong: Over-permissive IAM refers to roles/policies with excessive permissions, but this is a bucket policy issue.

CCSP Cloud Application Security Practice Question
This CCSP practice question tests your understanding of cloud application security. 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 developer configures an AWS S3 bucket to allow public access by setting a bucket policy that grants 's3:GetObject' to 'Principal: *'. Which vulnerability does this introduce?
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
✓
Exposed S3 bucket
Exposing an S3 bucket to anonymous access allows anyone to read objects, leading to data exposure. This is a common cloud misconfiguration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Mass assignment
Why it's wrong here
Mass assignment relates to object binding, not cloud storage configuration.
- ✗
SSRF vulnerability
Why it's wrong here
SSRF involves server-side requests, not bucket policies.
- ✓
Exposed S3 bucket
Why this is correct

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
