AWS Lambda functions now support full IAM resource-based policies

AWS Lambda functions now support full Identity and Access Management (IAM) resource-based policies , enabling platform admins and security teams to define granular access permissions using the full capabilities of AWS IAM. With full IAM resource-based policies, you can define permissions for multiple principals and actions in a single policy document and leverage the full range of IAM condition keys . Previously, Lambda functions required customers to add permissions individually per principal.
