AWS Certificate Manager (ACM): An In-Depth Overview
- AWS Certificate Manager (ACM) simplifies SSL/TLS certificate management within AWS environments, handling tasks like provisioning and renewing certificates.
- Understanding key concepts like Certificate Authorities (CAs), SSL/TLS, encryption in transit, and PKI is crucial for utilizing AWS ACM effectively.
- SSL/TLS certificates authenticate websites/services, encrypt data, and play a vital role in secure data transmission over the internet.
- AWS ACM offers both public (issued by trusted CAs) and private certificates (internal use), catering to diverse security needs.
- Use cases for AWS ACM include securing Load Balancers, CloudFront for content delivery, API Gateway, IoT Core, and internal applications.
- Automation features in AWS ACM, like automatic certificate renewal and integration with AWS Config and EventBridge, enhance security and manageability.
- Best practices include leveraging automatic renewal, limiting access to certificates with IAM policies, using private certificates for internal services, and monitoring with AWS Config.
- Combining monitoring and automation tools ensures proactive certificate management, reducing the risks of service outages or compromised security.
- Overall, AWS ACM streamlines SSL/TLS certificate management, enhances security, and reduces operational overhead for applications requiring secure communication.
