Explanation
AWS Certificate Manager (ACM) is the correct service for securing web applications with SSL/TLS encryption because:
- ACM provides SSL/TLS certificates that can be used to encrypt traffic between clients and web applications
- It automatically handles certificate provisioning, deployment, and renewal
- ACM certificates can be easily integrated with AWS services like Elastic Load Balancers, CloudFront distributions, and API Gateway
- The service is free when used with supported AWS services
Why other options are incorrect:
- AWS WAF: Web Application Firewall - protects against web exploits, not SSL/TLS encryption
- AWS Shield: DDoS protection service - protects against distributed denial of service attacks
- Amazon VPC: Virtual Private Cloud - provides network isolation and segmentation, not SSL/TLS encryption
ACM is specifically designed to simplify the process of obtaining, managing, and deploying SSL/TLS certificates for AWS workloads.
