SCS-C02 Security Logging and Monitoring Practice Question
This SCS-C02 practice question tests your understanding of security logging and monitoring. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 security engineer needs to be alerted when an IAM user attempts to modify an S3 bucket policy. Which method is the MOST efficient?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an Amazon CloudWatch Events rule that matches the PutBucketPolicy API call and triggers an SNS notification
Option C is correct because Amazon CloudWatch Events (now Amazon EventBridge) can directly capture the PutBucketPolicy API call as a real-time event and trigger an SNS notification without any additional compute or polling. This is the most efficient method as it requires no log parsing, no custom code, and no additional infrastructure, providing immediate alerting with minimal overhead.
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 VPC Flow Logs and analyze for S3 API traffic
Why it's wrong here
Flow logs capture network traffic, not API calls.
✗
Configure an AWS Config rule to detect changes and invoke a Lambda function
Why it's wrong here
Config can detect changes but is not the most efficient for real-time alerting.
✓
Create an Amazon CloudWatch Events rule that matches the PutBucketPolicy API call and triggers an SNS notification
Why this is correct
CloudWatch Events can match API calls from CloudTrail.

✗
Enable S3 server access logs and parse them for PutBucketPolicy entries
Why it's wrong here
Server access logs track object-level requests, not management actions.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often overcomplicate the solution by choosing log-based methods (A or D) or evaluation-based methods (B), missing that CloudWatch Events provides the simplest and most direct real-time alerting for specific API calls without additional overhead.
Detailed technical explanation
How to think about this question
CloudWatch Events (EventBridge) uses a default event bus that captures AWS API calls via CloudTrail; a rule with an event pattern matching the source as 'aws.s3' and detail.eventName as 'PutBucketPolicy' triggers the target (SNS topic) in near real-time. This approach leverages CloudTrail's management event logging, which is enabled by default and records all IAM user actions, ensuring no additional configuration is needed beyond the rule. In a real-world scenario, this method can also be combined with SNS to trigger Lambda for automated remediation, such as reverting the policy change.

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 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.
