Answer Description

Using identity and access management (IAM) roles and permissions is the best measure to enhance security in a serverless computing environment because it ensures that each part of the application has the necessary permissions, and no more, to perform its function. This principle of least privilege minimizes the risk of unauthorized access. Regularly monitoring and updating these roles further ensures that access remains controlled and limited.
