Implementing security throughout the Infrastructure as Code lifecycle to prevent misconfigurations and security gaps.
IaC Security Overview
Infrastructure as Code (IaC) enables rapid infrastructure deployment but introduces risks if not properly secured. Organizations must scan IaC for misconfigurations, implement policy-as-code, perform code reviews, and monitor deployed infrastructure for compliance violations.
Secrets in IaC
Secrets should never be embedded in IaC code. Tools should automatically detect and prevent hardcoded credentials. Use external secrets management services and reference them from IaC.
Policy as Code
Policy-as-code tools enforce compliance during deployment. Before infrastructure is deployed, policies should validate: encryption is enabled, network access is restricted, logging is configured, and other compliance requirements are met.
Code Review Process
IaC changes should go through code review before deployment. Reviewers should verify: security controls are present, least-privilege principles are followed, and policies are satisfied.
Scanning and Validation
Automated tools should scan IaC for known misconfigurations and security issues. Deployment should be prevented if issues are found.
Continuous Compliance
Deployed infrastructure should be monitored for compliance with policies. Configuration drift should trigger alerts or automatic remediation.
