Which of the following AWS services focuses specifically on enhancing application security through vulnerability assessments?

Amazon Inspector is designed specifically to enhance application security by conducting automated vulnerability assessments on applications deployed in Amazon EC2 instances and on container images stored in Amazon ECR. It assists in identifying security vulnerabilities or deviations from best practices, providing detailed findings that enable developers and security teams to address potential risks before they are exploited.

This service uses a variety of predefined security rules based on industry standards and best practices, allowing it to evaluate the security posture of the application comprehensively. By integrating with AWS services, Amazon Inspector helps streamline the process of ensuring that applications are secure and compliant, making it an essential tool in the AWS security ecosystem.

The other options serve different purposes:

• Amazon CloudTrail focuses on logging and monitoring API activity to aid in audit and compliance, but does not directly assess security vulnerabilities in applications.

• Amazon CloudFront is a content delivery network (CDN) that speeds up the delivery of web content but does not specifically address security vulnerabilities at the application level.

• Amazon RDS, while it provides managed database services, does not specialize in vulnerability assessment; rather, it focuses on database management, scaling, and availability.

Thus, Amazon Inspector clearly stands out as the service dedicated to vulnerability assessments, ensuring enhanced application security.
