- A
AWS Security Hub
Why wrong: Security Hub aggregates security findings from multiple services including Inspector, but doesn't perform the underlying vulnerability scanning itself.
- B
Amazon Inspector
Inspector continuously scans EC2 instances and ECR container images for vulnerabilities and network exposure issues, generating prioritized findings.
- C
AWS Config
Why wrong: AWS Config assesses configuration compliance against rules, but doesn't scan for software vulnerabilities or CVEs.
- D
Amazon Macie
Why wrong: Macie uses ML to discover and protect sensitive data in S3, not to assess infrastructure vulnerabilities.
Question 428 of 1,024
Amazon Inspector for Vulnerability Scanning
This CLF-C02 practice question tests your understanding of security and compliance. 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.
Which AWS service continuously assesses your AWS resources for security vulnerabilities, unintended network exposure, and deviations from security best practices?

Correct answer & explanation
✓
Amazon Inspector
Amazon Inspector is a vulnerability management service that continuously scans AWS workloads for software vulnerabilities and unintended network exposure. It uses a combination of network reachability analysis and agent-based or agentless assessments to detect deviations from security best practices, such as missing patches or open ports to the internet.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

AWS Security Hub
Why it's wrong here
Security Hub aggregates security findings from multiple services including Inspector, but doesn't perform the underlying vulnerability scanning itself.

Amazon Inspector
Why this is correct
Inspector continuously scans EC2 instances and ECR container images for vulnerabilities and network exposure issues, generating prioritized findings.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Security Hub (a central dashboard for findings) with the actual scanning service, leading them to choose Security Hub instead of Inspector, even though Security Hub does not perform the underlying vulnerability assessments.
Detailed technical explanation
How to think about this question
Amazon Inspector uses a combination of network reachability analysis (which checks for unintended network access by analyzing VPC flow logs and security group rules) and host assessments (via the AWS Systems Manager Agent or agentless snapshot analysis) to identify CVEs, CIS benchmarks, and common vulnerabilities. A subtle behavior is that Inspector’s network reachability findings can detect if a resource is directly exposed to the internet on a specific port, even if the resource itself is patched, which is a common oversight in security assessments.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
