Cevap

Under the AWS Shared Responsibility Model for AWS Lambda, the customer is responsible for writing and securing the application code and configuring Identity and Access Management (IAM) execution roles.
In serverless compute services like AWS Lambda, the boundary of responsibility shifts upwards. AWS manages the physical security, virtual machines, operating system, and the runtime software stack. The customer remains responsible for configuration and data management, specifically securing the application code written for the function and configuring IAM execution roles to control access to other AWS resources.

Adım Adım Çözüm

1
Identify the AWS service model type for AWS Lambda.
AWS Lambda is a serverless (managed) service where physical infrastructure, virtualization, operating systems, and managed runtime environments are handled entirely by AWS.
Understanding the service model helps determine the boundary of shared responsibility.
2
Distinguish between responsibilities for security 'of' the cloud (AWS) and security 'in' the cloud (customer) for Lambda.
AWS secures the execution environment, OS patching, runtime version maintenance, and physical hardware. The customer secures their own code, configuration settings, and access control (IAM).
This separation determines the specific operational tasks assigned to each party.
