Assess and Correct an Insecure Amazon EFS Deployment Using Migration Paths

In this lab, you will use the CLI (Command Line Interface) and AWS Console, and will first determine that Amazon Elastic File System (EFS) may not meet current security expectations. You will then mount a second EFS which is set up more securely, and migrate the data from the first EFS to the more secure file system.

  1. Challenge

    Inspect an existing Amazon EFS configuration

    Inspect the configuration of an existing Amazon Elastic File System (EFS) using the AWS CLI. By reviewing the file system properties, identify whether the legacy storage environment meets current security expectations such as encryption and compliance requirements.

  2. Challenge

    Mount an Amazon EFS file system on an EC2 instance

    Mount an Amazon EFS file system to an EC2 instance using the Amazon EFS mount helper utilities. This establishes network-based file system access and enables the instance to interact with the storage environment.

  3. Challenge

    Examine files stored in the legacy environment

    Examine the files stored in the mounted legacy EFS file system to understand the structure and contents of the existing data environment prior to migration.

  4. Challenge

    Mount a second EFS file system

    Mount a second Amazon EFS file system that represents a secure destination environment. This allows the EC2 instance to access both the legacy and secure storage systems simultaneously.

  5. Challenge

    Migrate data between file systems

    Migrate application data from the legacy EFS file system to the secure EFS file system. This step simulates a storage migration workflow commonly used when transitioning workloads to compliant storage architectures.

  6. Challenge

    Verify the migration

    Verify that the migration completed successfully by confirming that the files copied from the legacy environment are present and accessible on the secure EFS file system.
