CRISC Practice Question: Based on the exhibit, what is the PRIMARY risk…
Exhibit
Refer to the exhibit.
JSON policy snippet:
```json
{
"effect": "Allow",
"principal": "*",
"action": "s3:GetObject",
"resource": "arn:aws:s3:::critical-data/*",
"condition": {
"IpAddress": {
"aws:SourceIp": "10.0.0.0/8"
}
}
}
```Based on the exhibit, what is the PRIMARY risk associated with this cloud storage bucket policy?
⚠ Common exam trap
The trap is that candidates may focus on the IP range or subnet details, but the actual policy grants full public access, making unauthenticated access the primary risk.
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 permits unauthenticated access to sensitive data [CORRECT]
The cloud storage bucket policy grants public read access to the bucket. This permits any unauthenticated user on the internet to read objects in the bucket, exposing sensitive data without requiring credentials.
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 allows access to all storage buckets in the account [wrong]
Why it's wrong here
Resource is specific to critical-data bucket.
- ✗
The policy denies access to legitimate users from outside the subnet [wrong]
Why it's wrong here
Denying access is a control, not a risk; the risk is overly broad access.
- ✓
The policy permits unauthenticated access to sensitive data [CORRECT]
Why this is correct
The principal is '*', meaning any user (including unauthenticated) can access if from the allowed IP range.
- ✗
The policy uses an incorrect IP range that blocks all traffic [wrong]
Why it's wrong here
10.0.0.0/8 is a private range, but that doesn't block all; it allows internal traffic.
