Securing Serverless Functions
When to Use
- When deploying Lambda functions or Azure Functions with access to sensitive data or cloud APIs
- When auditing existing serverless workloads for overly permissive IAM roles
- When integrating serverless functions into a DevSecOps pipeline with automated security scanning
- When hardcoded secrets or vulnerable dependencies are discovered in function code
- When establishing runtime monitoring for serverless workloads to detect injection or credential theft
Do not use for container-based compute security (see securing-kubernetes-on-cloud), for API Gateway configuration (see implementing-cloud-waf-rules), or for serverless architecture design decisions.
Prerequisites
- AWS Lambda, Azure Functions, or GCP Cloud Functions with deployment access
- CI/CD pipeline with dependency scanning tools (npm audit, Snyk, Dependabot)
- AWS Secrets Manager, Azure Key Vault, or HashiCorp Vault for secrets management
- CloudWatch, Application Insights, or Cloud Logging for function monitoring
