```An architect reviews this S3 bucket policy. What security concern should be raised?
⚠ Common exam trap
ISC2 often tests the misconception that an IP restriction alone ensures security, when in fact it still allows anonymous access from any user within that range, bypassing authentication and IAM controls.
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
✓
The policy grants access to all users from the specified IP range.
The policy grants s3:GetObject access to all users (Principal: "*") from the specified IP range, which means any unauthenticated user on the internet within that IP range can read objects in the bucket. This violates the principle of least privilege and exposes data to potential unauthorized access, as the policy does not require authentication or additional authorization checks.
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 grants access to all users from the specified IP range.
Why this is correct
Without a Principal, the policy applies to all users (including anonymous) from that IP range.
- ✗
The policy allows s3:GetObject from any source.
Why it's wrong here
It restricts by IP address.
- ✗
The policy allows s3:GetObject only to the specific bucket.
Why it's wrong here
That is not a concern; it's expected.
- ✗
The policy does not restrict access to authenticated users.
Why it's wrong here
Concern is more about missing Principal; option A is more precise.
