Key Features of Amazon Inspector:
1. Automated Security Assessments: Amazon Inspector continuously scans your AWS workloads for software vulnerabilities and unintended network exposure. It automatically discovers and scans running Amazon EC2 instances, container images in Amazon ECR, and AWS Lambda functions.
2. Vulnerability Management: The service identifies security vulnerabilities in your applications by comparing them against a comprehensive database of Common Vulnerabilities and Exposures (CVEs) and network reachability issues.
3. Risk Scoring: Amazon Inspector provides a risk score for each finding, helping you prioritize remediation efforts. Findings are ranked based on severity, making it easier to address the most critical issues first.
4. Integration with AWS Services: Inspector integrates seamlessly with AWS Security Hub, providing a centralized view of security findings across your AWS environment. It also works with Amazon EventBridge for automated workflows.
5. Continuous Monitoring: Unlike traditional point-in-time assessments, Amazon Inspector provides continuous monitoring and automatically rescans resources when changes occur, such as installing new software or deploying new instances.
6. Detailed Findings: The service provides detailed reports about identified vulnerabilities, including affected resources, severity levels, and remediation guidance.
Benefits for Cloud Practitioner Exam:
- Understand that Inspector is an automated vulnerability management service
- Know it supports EC2 instances, ECR container images, and Lambda functions
- Recognize its role in maintaining security compliance
- Remember it provides continuous scanning capabilities
Amazon Inspector helps organizations meet compliance requirements and maintain a strong security posture by providing actionable insights into potential security weaknesses within their AWS infrastructure.

What is Amazon Inspector?
Amazon Inspector is an automated security assessment service that helps improve the security and compliance of applications deployed on AWS. It automatically assesses applications for exposure, vulnerabilities, and deviations from best practices.
Why is Amazon Inspector Important?
Security is a critical component of any cloud infrastructure. Amazon Inspector is important because it:
• Automates vulnerability detection - Continuously scans workloads for software vulnerabilities and unintended network exposure • Reduces manual effort - Eliminates the need for manual security assessments • Improves compliance posture - Helps organizations meet regulatory requirements by identifying security gaps • Provides actionable findings - Delivers detailed reports with prioritized recommendations for remediation • Integrates with AWS ecosystem - Works seamlessly with other AWS services like Security Hub and EventBridge
How Does Amazon Inspector Work?
Amazon Inspector operates through the following process:
1. Automatic Discovery - Inspector automatically discovers eligible AWS resources including EC2 instances, container images in Amazon ECR, and Lambda functions
3. Risk Scoring - Each finding receives a severity score based on factors like exploitability and potential impact
4. Reporting - Findings are consolidated in the Inspector console and can be exported or integrated with other tools
Key Features to Remember:
• Agentless scanning for EC2 instances (uses AWS Systems Manager) • Container image scanning in Amazon ECR • Lambda function scanning for code and dependency vulnerabilities • Integration with AWS Security Hub for centralized security view • Automated and continuous assessment capabilities
Amazon Inspector vs. Other Security Services:
• Amazon Inspector - Vulnerability scanning for EC2, ECR, and Lambda • Amazon GuardDuty - Threat detection and monitoring • AWS Config - Configuration compliance checking • AWS Security Hub - Aggregates findings from multiple services
Exam Tips: Answering Questions on Amazon Inspector
1. Remember the scope - Inspector scans EC2 instances, ECR container images, and Lambda functions. If a question asks about vulnerability scanning for these resources, Inspector is likely the answer.
2. Focus on automation - When questions mention automated vulnerability assessment or continuous scanning, think Amazon Inspector.
3. Distinguish from GuardDuty - Inspector finds vulnerabilities in your resources; GuardDuty detects threats and suspicious activity. This distinction appears frequently in exams.
4. Know the integration points - Inspector works with Security Hub, EventBridge, and Systems Manager. Questions may test your knowledge of these integrations.
5. Understand the use case - If a scenario describes needing to identify CVEs, software vulnerabilities, or network exposure in EC2 or containers, Amazon Inspector is the correct choice.
6. Remember it is a regional service - Inspector operates within AWS regions where you enable it.
7. Cost considerations - Inspector pricing is based on the number of instances scanned and container images assessed. Be aware that it is not a free service.
Common Exam Scenarios:
• A company needs to scan EC2 instances for known vulnerabilities → Amazon Inspector • An organization wants to check container images for security issues before deployment → Amazon Inspector with ECR scanning • A team needs automated security assessments for their Lambda functions → Amazon Inspector
