SOA-C02 Security and Compliance Practice Question
A company's security team requires that all API calls to AWS services are encrypted in transit using TLS 1.2 or higher. Which TWO actions should be taken to enforce this?
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
✓
Use AWS CloudTrail to monitor for API calls using TLS 1.0 and generate alerts.
Options C and E are correct. Using AWS CloudTrail to monitor for API calls using TLS 1.0 allows the security team to detect non-compliant requests and generate alerts. Creating an SCP that denies AWS API calls using protocols lower than TLS 1.2 enforces encryption in transit at the organizational level. Option A is incorrect because CloudTrail logging alone does not enforce encryption; it only records events. Option B is incorrect because EC2 security groups control network traffic to instances, not API calls to AWS services. Option D is incorrect because IAM policies can require HTTPS via the aws:SecureTransport condition, but cannot enforce a specific TLS version like 1.2.
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 AWS CloudTrail to log all API calls.
Why it's wrong here
CloudTrail logs events but does not enforce encryption.
- ✗
Configure EC2 security groups to only allow HTTPS traffic.
Why it's wrong here
Security groups apply to EC2 instances, not API calls.
- ✓
Use AWS CloudTrail to monitor for API calls using TLS 1.0 and generate alerts.
Why this is correct
CloudTrail can log TLS version; monitoring and alerting can detect non-compliance.
- ✗
Create an IAM policy that denies access unless the request uses TLS 1.2.
Why it's wrong here
IAM policies do not have a condition for TLS version.
- ✓
Create an SCP that denies AWS API calls using protocols lower than TLS 1.2.
Why this is correct
SCPs can enforce TLS version for API calls.
