Cloud Security Automation
EBS Encryption Automation
An Infrastructure as Code approach for detecting unencrypted EBS resources and coordinating repeatable remediation through AWS Config, Systems Manager, and CloudFormation.
Problem
Storage encryption compliance should not depend on manual review.
EBS encryption is a basic cloud-security control, but manually detecting and remediating non-compliant resources does not scale well across changing AWS environments. The objective was to make detection and remediation repeatable, reviewable, and driven by infrastructure code.
Context
The design separates compliance detection from remediation. AWS Config evaluates resource state, while automation handles the operational workflow required to move a resource toward an encrypted state.

Implementation
CloudFormation defines the compliance and automation resources so the control can be deployed consistently instead of configured manually.
AWS Config identifies EBS resources that do not meet the expected encryption policy.
Systems Manager provides the automation layer required for controlled remediation steps and operational workflow.
IAM permissions are scoped around the actions needed by the compliance and remediation components.
Security
The design focuses on encryption at rest, least-privilege IAM, repeatable infrastructure deployment, and auditable remediation. AWS KMS-backed encryption can be incorporated according to the organization's key-management policy.
Observability
AWS Config provides compliance state, while Systems Manager execution history provides operational visibility into automation runs and failures.
Results
The solution establishes a reusable pattern for moving EBS encryption from a manual review task toward policy-driven, Infrastructure as Code-based compliance automation.
Lessons
Compliance detection and remediation should remain separate concerns.
Infrastructure as Code makes security controls easier to review and reproduce.
Automated remediation still requires careful IAM and failure handling.
Encryption controls are stronger when they are continuously evaluated.
