The correct answer is to enable S3 server access logs and Amazon GuardDuty with S3 protection. S3 server access logs capture detailed records of every request made to the bucket, including the requester, action, and response status, fulfilling the compliance requirement for logging all access. GuardDuty then analyzes these logs and other data sources to detect suspicious activity in real time, such as unusual API calls or credential theft, meeting the real-time threat detection need. On the AWS Certified Security Specialty SCS-C02 exam, this question tests your understanding of the distinction between CloudTrail management events, which do not log S3 data events by default, and dedicated S3 logging services. A common trap is assuming CloudTrail alone suffices, but it requires an additional data event trail for object-level logging, whereas server access logs are purpose-built for this. Remember the memory tip: “CloudTrail for the trail, Server Access Logs for the details, GuardDuty for the bad guys.”
SCS-C02 Data Protection Practice Question
This SCS-C02 practice question tests your understanding of data protection. 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 company stores sensitive customer data in Amazon S3. The security team has enabled default encryption with SSE-S3 on the bucket. The compliance team requires that all access to the bucket be logged and that any unauthorized access attempts be detected in real time. The company has AWS CloudTrail enabled. Which additional steps should the security team take to meet the compliance requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable S3 server access logs and enable Amazon GuardDuty with S3 protection
Option C is correct because enabling S3 server access logs captures all requests, and Amazon GuardDuty can detect suspicious activity in real time. Option A is wrong because CloudTrail management events do not log data events by default. Option B is wrong because VPC Flow Logs do not log S3 access. Option D is wrong because AWS Config is for configuration changes, not real-time threat detection.
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.
✓
Enable S3 server access logs and enable Amazon GuardDuty with S3 protection
Why this is correct
Server access logs provide detailed logging; GuardDuty provides real-time threat detection.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enable AWS Config rules to detect unauthorized access
Why it's wrong here
Config rules are for configuration compliance, not real-time detection.
✗
Enable CloudTrail data events for the S3 bucket and use Amazon Detective
Why it's wrong here
CloudTrail data events can log, but Detective is not real-time.
✗
Enable VPC Flow Logs and use Amazon Athena to analyze logs
Why it's wrong here
VPC Flow Logs do not capture S3 access.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
