Security in Amazon Lambda

This chapter covers security, governance, and compliance for Amazon Lambda. The data protection, compliance, resilience, and infrastructure security guidance applies to all Lambda compute types. Access control and encryption have compute-type-specific details: for Lambda Web Functions, see Lambda Web Function permissions, Lambda Web Function endpoint access control, and Encryption at rest for Web Functions; for Lambda MicroVMs, see Security and permissions. The remaining topics in this chapter describe Lambda Event Functions.

Cloud security at Amazon is the highest priority. As an Amazon customer, you benefit from a data center and network architecture that is built to meet the requirements of the most security-sensitive organizations.

Security is a shared responsibility between Amazon and you. The shared responsibility model describes this as security of the cloud and security in the cloud:

  • Security of the cloud – Amazon is responsible for protecting the infrastructure that runs Amazon Web Services services in the Amazon Cloud. Amazon also provides you with services that you can use securely. Third-party auditors regularly test and verify the effectiveness of our security as part of the Amazon compliance programs. To learn about the compliance programs that apply to Amazon Lambda, see Amazon Web Services services in Scope by Compliance Program.

  • Security in the cloud – Your responsibility is determined by the Amazon service that you use. You are also responsible for other factors including the sensitivity of your data, your company's requirements, and applicable laws and regulations.

This documentation helps you understand how to apply the shared responsibility model when using Lambda. The following topics show you how to configure Lambda to meet your security and compliance objectives. You also learn how to use other Amazon Web Services services that help you to monitor and secure your Lambda resources. Topics include compliance validation, data protection, identity and access management, interface VPC endpoints, and resilience.
