AWS Lambda Security
AWS Lambda Security 是什么?
AWS Lambda SecurityThe security model and operational hardening of AWS Lambda functions — execution role least-privilege, layer integrity, code-signing, environment-variable secrets, VPC posture, and runtime threats specific to ephemeral compute.
AWS Lambda security combines familiar appsec concerns with serverless-specific risks. Each function ships with an execution IAM role that the function code can assume in-process via STS, so over-broad role policies turn a single vulnerable function into broad cloud access — the leading Lambda finding in cloud audits. Lambda layers and container images introduce a software-supply-chain surface: a malicious or compromised layer is shared across many functions and rarely re-scanned. Environment variables are the default way to inject secrets but are visible in IAM `lambda:GetFunctionConfiguration` and to anyone who can invoke `aws lambda update-function-configuration`; Secrets Manager / Parameter Store references are preferred. VPC-attached Lambdas inherit network posture: a function in a misconfigured subnet can reach internal services it should not. Runtime threats — cryptojacking miners, info-stealers — have appeared but are less common than in EC2 due to short-lived execution. AWS Code Signing and Lambda function URLs added authentication and signed-deployment options in 2022. Defenses include least-privilege execution roles, layer pinning and signing, secrets via Secrets Manager not env vars, dedicated VPC/subnet design, CloudTrail data events for invocation logs, and runtime monitoring (Sysdig, Datadog, AWS GuardDuty Runtime Monitoring for Lambda).
● 示例
- 01
A function reads secrets from AWS Secrets Manager at cold start, with its execution role limited to one specific secret ARN.
- 02
GuardDuty Runtime Monitoring flags a Lambda function that began making outbound DNS queries to a known mining pool.
