Ultimate access to all questions.
A company with numerous AWS Lambda functions has identified a security concern where sensitive data is stored in plaintext within environment variables, accessible via the Lambda console. This sensitive data consists of only a few characters. What is the most cost-effective solution to secure this sensitive information?
A
Implement IAM policies within the Lambda console to restrict access to the environment variables.
B
Employ AWS Step Functions to manage the environment variables, granting runtime access with IAM permissions limited to the necessary Lambda functions.
C
Utilize AWS Secrets Manager to store the environment variables, ensuring runtime access with IAM permissions that are restricted to the required Lambda functions.
D
Leverage AWS Systems Manager Parameter Store to store the environment variables as secure string parameters, providing runtime access with IAM permissions limited to the necessary Lambda functions.
