EFS Security
Storage & DatabaseAmazon EFS (Elastic File System) provides scalable NFS file storage. Security is managed through multiple layers.
Network Security
- EFS mount targets live in VPC subnets - accessible only from within the VPC
- Security groups on mount targets control which EC2 instances or containers can connect
- No public access possible - EFS is VPC-only by design
Encryption
- At Rest: AES-256 using KMS; must be enabled at creation
- In Transit: TLS 1.2 encryption using the EFS mount helper
Access Control
- IAM Authorization: file system policies and IAM identity policies for mount/read/write
- Access Points: enforce POSIX user/group identity and root directory per application
- POSIX Permissions: standard Unix file permissions (owner, group, other)
