AWS Cloud Development Kit - From Beginner to Professional - Grant Least Privileges to Your Lambda Functions

The video tutorial explains how to add fine-grained privileges to AWS Lambda functions using AWS CDK. It covers the deployment of a simple Lambda function that lists S3 buckets and stores them in a DynamoDB table. Initially, the function is deployed without additional privileges, leading to access errors. The tutorial then demonstrates how to add managed policies for S3 access and fine-grained access for DynamoDB, ensuring the Lambda function has the necessary permissions to perform its tasks.

Why is it important to provide fine-tuned privileges to AWS Lambda functions?

• To enhance security by granting only necessary permissions

• To increase the execution speed of Lambda functions

• To allow Lambda functions to access all AWS resources

• To reduce the cost of AWS services

What is the purpose of the Lambda function in the provided example?

• To delete S3 buckets

• To list S3 buckets and store them in a DynamoDB table

• To modify DynamoDB tables

• To create new S3 buckets

What issue arises when the Lambda function is deployed without additional privileges?

• The function cannot access any AWS services

• The function deletes all items in the DynamoDB table

• The function encounters an access denied error when listing S3 buckets

• The function runs successfully without errors

Which managed policy is added to the Lambda function to resolve the S3 access issue?

• Amazon S3 Full Access

• Amazon S3 Read-Only Access

• Amazon EC2 Full Access

• Amazon DynamoDB Full Access

After adding the S3 read-only access policy, what error does the Lambda function encounter?

• Access denied when listing S3 buckets

• Access denied when writing to DynamoDB

• Access denied when deleting S3 buckets

• Access denied when reading from DynamoDB

How is the Lambda function's access to DynamoDB restricted in the final implementation?

• By denying access to all DynamoDB tables

• By granting full access to all DynamoDB tables

• By granting write-level access to a specific table

• By granting read-only access to a specific table

What is the benefit of implementing fine-grained privileges for AWS Lambda functions?

• It allows functions to run faster

• It reduces the cost of AWS services

• It enhances security by limiting access to specific resources

• It simplifies the deployment process
