AWS memorydb: Fix broken links in IAM authentication documentation

Service: memorydb · 2026-08-19 · Documentation low

File: memorydb/latest/devguide/auth-iam.md

Summary

Corrected URLs for Signature Version 4 and pre-signed request documentation by removing double slashes.

Security assessment

The change only fixes broken hyperlinks without altering security content or addressing vulnerabilities.

Evidence

+You first need to generate the short-lived IAM authentication token using an [AWS SigV4 pre-signed request](https://docs.aws.amazon.com/general/latest/gr/sigv4-signed-request-examples.html). After that you provide the IAM authentication token as a password when connecting to a MemoryDB cluster, as shown in the example below.

-With IAM Authentication you can authenticate a connection to MemoryDB using AWS IAM identities, when your cluster is configured to use Valkey or Redis OSS version 7 or above. This allows you to strengthen your security model and simplify many administrative security tasks. With IAM Authentication you can configure fine-grained access control for each individual MemoryDB cluster and MemoryDB user and follow least-privilege permissions principles. IAM Authentication for MemoryDB works by providing a short-lived IAM authentication token instead of a long-lived MemoryDB user password in the `AUTH` or `HELLO` command. For more information about the IAM authentication token, refer to the [Signature Version 4 signing process](https://docs.aws.amazon.com//general/latest/gr/signature-version-4.html) in the the AWS General Reference Guide and the code example below.
