AWS vpn high security documentation change

Service: vpn · 2026-06-25 · Security-related high

File: vpn/latest/clientvpn-admin/security-best-practices.md

Summary

Added VPN client usage recommendations and enforced cryptographic algorithms for TLS and data channels

Security assessment

Explicitly mandates secure configurations by prohibiting cipher/TLS modifications and specifying approved cryptographic algorithms (TLS 1.3/1.2 protocols and AES-256-GCM), directly addressing cryptographic security

+###### Use the AWS provided VPN client
+
+Use the AWS provided client for AWS Client VPN, available from the [AWS Client VPN download page](https://aws.amazon.com/vpn/client-vpn-download/).
+
+###### Use the exported client configuration
+
+Use the client configuration file exported from your AWS Client VPN endpoint. For more information, see [Export the client configuration file](./export-client-config-file.html). Do not modify the cipher or TLS settings in the configuration file. AWS Client VPN endpoints only support the following algorithms:
+
+  * TLS 1.3: `TLS_AES_256_GCM_SHA384` and `TLS_AES_128_GCM_SHA256`
+
+  * TLS 1.2: `TLS-ECDHE-RSA-WITH-AES-256-GCM-SHA384`, `TLS-ECDHE-RSA-WITH-AES-128-GCM-SHA256`, `TLS-ECDHE-ECDSA-WITH-AES-256-GCM-SHA384`, and `TLS-ECDHE-ECDSA-WITH-AES-128-GCM-SHA256`
+
+  * Data channel: `AES-256-GCM`
