CCSP Cloud Platform and Infrastructure Security Practice Question
This CCSP practice question tests your understanding of cloud platform and infrastructure 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The policy grants public read access to all objects.
Option D is correct because the IAM policy statement includes `"Principal": "*"` and `"Effect": "Allow"` without any condition restricting access, which grants public read access to all objects in the S3 bucket. This violates the principle of least privilege and exposes sensitive data to anyone on the internet, making it a critical security 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.
✗
The policy is missing a condition for encryption.
Why it's wrong here
Missing encryption condition is a concern but not the primary issue.
✗
The policy does not specify a source IP.
Why it's wrong here
Source IP restriction is optional and not the primary issue.
✗
The policy allows all actions.
Why it's wrong here
The policy only allows s3:GetObject, not all actions.
✓
The policy grants public read access to all objects.
Why this is correct
Principal '*' with Allow effect makes the bucket publicly readable.
Clue confirmation
The clue word "primary" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the distinction between 'public access' and 'all actions' — candidates mistakenly think 'all actions' is the issue, but the trap is that the policy only grants read access, yet the public principal makes it a severe data exposure risk regardless of the action scope.
Detailed technical explanation
How to think about this question
Under the hood, S3 bucket policies are evaluated by AWS IAM before any request is processed; a `Principal: "*"` combined with `Effect: "Allow"` effectively bypasses any bucket-level block public access settings if those settings are not explicitly enabled. In real-world scenarios, this misconfiguration often leads to data breaches, as seen in numerous incidents where sensitive files like customer PII or configuration backups were scraped by automated crawlers. The policy also lacks a `Condition` block with `StringNotEquals` or `IpAddress` to restrict access, which would have mitigated the risk.

TExam Day Tips
→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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
