Does Amazon EFS support encryption at rest and in transit? If yes, then how can it be configured?

Yes, Amazon EFS supports both encryption at rest and in transit:

* **Encryption at rest:** Enabled when creating a file system, it uses industry-standard AES-256 to encrypt data on the server side.

* **Encryption in transit:** Achieved by setting up a TLS tunnel during file system mounting using the EFS mount helper.

What is the best way to share data securely between multiple AWS accounts?

The best way to share data securely between multiple AWS accounts is by using AWS Resource Access Manager (RAM) or AWS Resource Sharing. It allows you to share resources like Amazon S3 buckets or Amazon Aurora databases securely between accounts while controlling access permissions.

How do we access data stored on an EFS file system from an EC2 instance?

To access data stored on an EFS (Elastic File System) from an EC2 (Elastic Compute Cloud) instance, you simply mount the EFS file system onto the EC2 instance. This allows the EC2 instance to read and write files stored on the EFS.
