Why secure Lambda Functions using IAM Roles and Policies?
Securing the Lambda function using IAM roles and policies is a crucial task on the AWS cloud platform. This is so because for the following reasons :
- IAM attaches permissions to Lambda functions to ensure that only the intended services and resources should be accessed by AWS Lambda. By attaching the roles and permissions to the Lambda function, users can minimize the unauthorized access or misuse of AWS resources.
- IAM roles can be attached temporarily to the AWS Lambda function which minimizes the exposure of any long-term security credentials.
- If any unauthorized person tries to access the Lambda function, these IAM roles can restrict the actions that a Lambda function can perform on the cloud environment.
- IAM roles grant secure access to other AWS account’s Lambda functions.
In summary, we can say securing the Lambda function using IAM roles and policies is an essential task to maintain integrity and confidentiality on the AWS cloud platform.
Securing AWS Lambda Functions With IAM Roles And Policies
AWS Lambda is a serverless computing service that helps in executing code without any management of servers while AWS IAM is an essential security component that allows authorized individuals or services to have access of other AWS resources. These two AWS services are very important on the AWS cloud platform. Here in this guide, I have first discussed what is AWS Lambda service. Then discuss about AWS IAM service and why it is required to secure your Lambda function using IAM roles and policies. After this, I walked you through the different steps to create an IAM role and attach it to the Lambda function for secure access to other AWS services.
