Amazon Elastic File System now supports AWS Identity and Access Management for Network File System clients
You can now use AWS Identity and Access Management (IAM) to manage Network File System (NFS) access for Amazon Elastic File System (Amazon EFS). You can use IAM roles to identify NFS clients with cryptographic security and use IAM policies to manage client-specific permissions. This new capability provides a simplified way to manage access at scale in NFS environments and is complementary to network-based security controls. With IAM for NFS clients you can use the same tools and processes you use today for managing access to other AWS resources. Permission checks are logged to AWS CloudTrail so you can audit client access to your file system.
