The challenge of maintaining strong security across multiple AWS (Amazon Web Services) accounts is becoming increasingly complex. As DevOps practices accelerate deployment cycles, the need for a dynamic and integrated security strategy grows.
In this blog post, we’ll explore advanced techniques to enhance your AWS security posture using essential services like Security Hub, AWS Config, IAM Access Analyzer, CloudTrail, and GuardDuty. Additionally, we’ll demonstrate how to centralize monitoring and alerting with CloudWatch, enabling a unified overview of metrics, logs, and notifications across all your AWS environments. We’ve grounded our strategies in the AWS Security Reference Architecture as outlined in the AWS Prescriptive Guidance.
While the AWS Security Baseline guidance provides an excellent foundation for your initial steps in securing your cloud environment, adopting more sophisticated AWS security best practices is essential for advanced AWS compliance requirements. With a focus on automated cloud security measures , you can maintain a proactive stance against potential threats, streamlining security operations across your cloud infrastructure.
Moreover, we will be implementing these advanced security strategies for Synaptic, ensuring their AWS environments are secure and compliant with industry standards.
Our reference architecture employs a multi-account setup, where distinct AWS accounts are allocated for specific purposes such as central security and governance account, development, staging, and production environments( categorized as workload accounts ) and workspaces accounts ( with primary purpose of securely accessing the cloud resources by internal engineering teams ) . This segregation facilitates workload isolation and containment, minimizing the impact of security incidents across the system.
We have integrated AWS Security Hub into our architecture to centralize and aggregate security findings from various AWS services like Amazon GuardDuty, AWS Config, and IAM Access Analyzer. This integration enables us to have a unified view of our security posture and effectively detect and respond to security issues.
For the configuration of proactive monitoring, we utilized AWS Config service to continuously monitor and record configurations of AWS resources across all accounts. This helps us track changes, assess compliance against security best practices, and address any deviations from our security policies promptly.
IAM Access Analyzer is used to analyze resource policies and identify unintended access permissions and potential security risks. Enabling Access Analyzer in all accounts helped us to proactively detect and remediate access-related vulnerabilities.
To log API calls and user activity on AWS resources, we utilized AWS CloudTrail within each AWS account, providing a detailed history of actions and enabling us to monitor for unauthorized or suspicious behavior. Multi-region CloudTrail is active to enhance visibility into system activity.
For threat detection, Amazon GuardDuty is used for analyzing CloudTrail logs, VPC flow logs, and DNS logs to detect potential security threats such as malicious activity and unauthorized access attempts. GuardDuty is active across all accounts, enhancing our threat detection capabilities.
Centralized monitoring is achieved through a dedicated security tooling account that aggregates CloudWatch metrics and logs from all source AWS accounts using Cross account observability in AWS Cloudwatch service. This approach allows us to monitor the performance, health, and security status of resources centrally, providing a comprehensive view of our AWS environments , all at one place.
Furthermore, we have set up centralized alerting and notification using CloudWatch Events , Amazon SNS, AWS chatbot and Slack. This configuration ensures that our security teams receive timely alerts for any security findings or events detected across multiple AWS accounts, facilitating prompt incident response, effective remediation, and continuous security monitoring.
