This CCSP practice question tests your understanding of cloud data 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.
During a cloud migration, a company discovers that some sensitive data was inadvertently stored in an object storage bucket with public read access. The security team needs to determine the scope of exposure and remediate. What is the FIRST step they should take?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Review the bucket's access logs to identify any unauthorized access.
The first step is to review the bucket's access logs (e.g., AWS CloudTrail or S3 server access logs) to identify any unauthorized access. This determines the scope of exposure—who accessed the data, when, and from where—before taking any remediation action. Without this forensic step, the company cannot assess breach notification obligations or legal liability.
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.
✗
Notify the data protection authority.
Why it's wrong here
Notification should come after the scope is determined.
✗
Change the bucket's permission to private.
Why it's wrong here
While necessary, this should be done after preserving logs for forensic analysis.
✗
Immediately delete all objects in the bucket.
Why it's wrong here
Deleting objects without investigation could destroy evidence needed to assess the breach.
✓
Review the bucket's access logs to identify any unauthorized access.
Why this is correct
Access logs reveal who has accessed the data, which is crucial for scope assessment.
Clue confirmation

Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the principle of 'preserve evidence first'—candidates mistakenly jump to remediation (changing permissions or deleting objects) without first conducting forensic analysis to determine the scope of exposure.
Detailed technical explanation
How to think about this question
Cloud storage services like AWS S3, Azure Blob Storage, and Google Cloud Storage provide server access logs that record every request, including the requester's IP, user agent, and action (e.g., GET, PUT). These logs are typically delivered to a separate bucket or log service and can be analyzed to identify anomalous access patterns. In a real-world scenario, the security team might use tools like Amazon Athena or Splunk to query logs for public IPs or unauthenticated requests, which is critical for incident response and regulatory compliance (e.g., GDPR Article 33).

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 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.
