- A
Enable AWS Config managed rule to detect access key creation and trigger an SNS notification.
Why wrong: AWS Config rules evaluate resource configurations, not API calls; they are not designed for real-time API monitoring.
- B
Create a CloudWatch Events rule that matches the CreateAccessKey event and targets an SNS topic.
CloudWatch Events can filter specific API calls in real-time and trigger actions like SNS notifications.
- C
Use CloudWatch Logs Insights to run a query every minute on CloudTrail logs and send results to SNS.
Why wrong: This is not real-time and requires manual setup; CloudWatch Events is more efficient for real-time alerts.
- D
Configure CloudTrail to send logs to an S3 bucket and enable S3 event notifications to an SNS topic.
Why wrong: S3 event notifications occur when objects are created, but CloudTrail delivers logs in batches, causing delays; not real-time.
Quick Answer
The answer is to create a CloudWatch Events rule that matches the CreateAccessKey event and targets an SNS topic. This is the most efficient approach because CloudWatch Events (now part of Amazon EventBridge) provides real-time alert on IAM API calls by filtering the CloudTrail log stream for specific event names like CreateAccessKey, then routing that event directly to an SNS topic for immediate notification without any polling or manual queries. On the AWS Certified Security Specialty SCS-C02 exam, this scenario tests your understanding of the difference between log storage (CloudTrail), log analysis (CloudWatch Logs Insights), and event-driven automation (CloudWatch Events). A common trap is choosing CloudTrail itself, which only delivers logs to S3 and cannot natively send alerts, or selecting AWS Config, which tracks resource state changes but not individual API calls. Remember the memory tip: "Events for alerts, Trails for trails" — CloudWatch Events triggers real-time actions, while CloudTrail simply records the trail of API activity.
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 company uses AWS CloudTrail to log all API calls. The security team needs to be alerted when an IAM user creates a new access key. Which approach is most efficient?
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
Create a CloudWatch Events rule that matches the CreateAccessKey event and targets an SNS topic.
Option B is correct because CloudWatch Events can filter specific API calls and trigger a Lambda function to send notifications. Option A is incorrect because CloudTrail does not natively send alerts; it delivers logs to S3. Option C is incorrect because CloudWatch Logs Insights requires querying logs manually, not real-time alerting. Option D is incorrect because Config records resource changes but is not optimized for API call alerts.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Why it's wrong here
S3 event notifications occur when objects are created, but CloudTrail delivers logs in batches, causing delays; not real-time.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.

Same concept, more angles
2 more ways this is tested on SCS-C02
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A security engineer needs to be alerted when an IAM user attempts to modify an S3 bucket policy. Which method is the MOST efficient?
easy- A.Enable VPC Flow Logs and analyze for S3 API traffic
- B.Configure an AWS Config rule to detect changes and invoke a Lambda function
- ✓ C.Create an Amazon CloudWatch Events rule that matches the PutBucketPolicy API call and triggers an SNS notification
- D.Enable S3 server access logs and parse them for PutBucketPolicy entries
Why C: 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.
Variation 2. A company runs a critical application on Amazon EC2 instances in an Auto Scaling group. The security team needs to monitor for unauthorized changes to security groups. They have enabled AWS Config with the security-group-change detection rule. However, they notice that changes are being detected but not all changes trigger a notification. The team wants to ensure that every security group modification (create, delete, or rule change) sends an alert to the security operations center via Amazon SNS. The current setup: AWS Config rules evaluate resources periodically, and SNS notifications are sent only when the rule compliance status changes. What should the team do to achieve real-time alerts for all security group changes?
hard- A.Deploy Amazon GuardDuty and enable the Security Group Monitoring feature.
- ✓ B.Configure an Amazon EventBridge rule that matches API calls via CloudTrail for security group modifications and sends notifications to an SNS topic.
- C.Increase the frequency of AWS Config rule evaluations to every minute to reduce detection latency.
- D.Enable VPC Flow Logs and set up a metric filter for security group-related traffic anomalies.
Why B: The correct answer is B. CloudTrail logs all API calls, including security group modifications, in real time. By creating a CloudWatch Events (now Amazon EventBridge) rule that matches SecurityGroup events and targets SNS, the team can receive immediate notifications. Option A is incorrect because AWS Config rules are not real-time; they evaluate periodically or on configuration changes but are not designed for real-time alerting. Option C is incorrect because VPC Flow Logs monitor network traffic, not security group changes. Option D is incorrect because GuardDuty focuses on threat detection, not configuration changes.
