Managing infrastructure involves juggling various factors like application performance, reliability, and disaster recovery, but one often overlooked aspect is security. At ITSyndicate, an AWS partner, we prioritize security and let's delve into a case study to see how we handle it.
Start with the basics for VPC and IAM security by managing subnets, configuring IAM, and implementing minimal privileges. Ignoring these early on can lead to exponential problems as your project grows. For IAM, implement minimal privileges from the start and plan carefully to avoid future complications.
In our project, the EKS cluster's IAM Role is tailored to specific AWS services like Secrets Manager, KMS, RDS, and S3. VPC and subnet management involve asking key questions for each resource, ensuring necessary internet access, and making strategic decisions. For example, our EKS cluster uses private subnets for security, with specific resources like RDS in private subnets too.
Strategies for robust defense and proactive measures
Enhance security with AWS WAF and CloudFront for protection against layer seven attacks and effective DDoS mitigation. Secrets Manager in Kubernetes stores sensitive data, while AWS KMS offers versatile encryption integrated with various AWS services. Security observability is crucial, and we use AWS Config with SNS and Lambda integrations to track and respond to incidents promptly.
What's great about our security management is its scalability and ease of improvement over time. Features like AWS Shield Advanced and GuardDuty are ready for activation when needed. Regular key rotation is a fundamental security practice, coupled with granting the least access required. In our other guide, we discuss how GCP service account key rotation enhances security using Kubernetes and Python. This proactive approach ensures your infrastructure stays secure and operations run smoothly.
