Serverless computing with AWS Lambda cuts ops overhead but demands vigilant security. Use IAM roles with fine-grained permissions; avoid overly broad policies. Scan functions via AWS Inspector for vulnerabilities. X-Ray traces invocations for anomalies. API Gateway enforces WAF rules and JWT auth. Environment variables store secrets via SSM Parameter Store. Event-driven architectures need Dead Letter Queues for failure isolation. Compliance via GuardDuty detects crypto mining. This enables secure, auto-scaling apps.
