Infrastructure Security in Amazon S3 Glacier - Amazon S3 Glacier
VPC Endpoints

This page is only for existing customers of the S3 Glacier service using Vaults and the original REST API from 2012.

If you're looking for archival storage solutions we suggest using the S3 Glacier storage classes in Amazon S3, S3 Glacier Instant Retrieval, S3 Glacier Flexible Retrieval, and S3 Glacier Deep Archive. To learn more about these storage options, see S3 Glacier storage classes and Long-term data storage using S3 Glacier storage classes in the Amazon S3 User Guide. These storage classes use the Amazon S3 API, are available in all regions, and can be managed within the Amazon S3 console. They offer features like Storage Cost Analysis, Storage Lens, advanced optional encryption features, and more.

Infrastructure Security in Amazon S3 Glacier

As a managed service, Amazon S3 Glacier (S3 Glacier) is protected by the AWS global network security procedures that are described in the Amazon Web Services: Overview of Security Processes.

Access to S3 Glacier via the network is through AWS published APIs. Clients must support Transport Layer Security (TLS) 1.2. We recommend TLS 1.3 or later. Clients must also support cipher suites with Perfect Forward Secrecy (PFS) such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Diffie-Hellman Ephemeral (ECDHE). Most modern systems such as Java 7 and later support these modes. Additionally, requests must be signed using an access key ID and a secret access key that is associated with an IAM principal, or you can use the AWS Security Token Service (AWS STS) to generate temporary security credentials to sign requests.

VPC Endpoints

A virtual private cloud (VPC) endpoint enables you to privately connect your VPC to supported AWS services and VPC endpoint services powered by AWS PrivateLink without requiring an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. Although S3 Glacier does not support VPC endpoints directly, you can take advantage of Amazon S3 VPC endpoints if you access S3 Glacier as a storage tier integrated with Amazon S3.
