Use of long-term access keys for authentication between cloud resources increases the risk of key exposure and unauthorized secrets reuse. Amazon Web Services (AWS) has developed a solution to enable customers to securely authenticate Azure resources with AWS resources using short-lived tokens to reduce risks to secure authentication. In this post, we guide you through […]

This blog post provides recommendations that you can use to help improve resiliency in the unlikely event of disrupted availability of the global (now legacy) AWS Security Token Service (AWS STS) endpoint. Although the global (legacy) AWS STS endpoint https://sts.amazonaws.com is highly available, it’s hosted in a single AWS Region—US East (N. Virginia)—and like other […]

As of today, AWS STS is active by default in all AWS regions, for all customers. This means that your applications and services can immediately take advantage of reduced […]

By the end of November 2015, AWS Security Token Service (STS) will be active by default in all AWS regions, which means that your applications and services can call AWS STS in a region geographically closer to you. This change will optimize latencies and improve application performance. Additionally, the multiregional resiliency provided by AWS STS […]

The newly released whitepaper, Single Sign-On: Integrating AWS, OpenLDAP, and Shibboleth, will help you integrate your existing LDAP-based user directory with AWS. When you integrate your existing directory with AWS, your users can access AWS by using their existing credentials. This means that your users […]

AWS Security Token Service (STS), which enables your applications to request temporary security credentials, is now available in every AWS region. Previously, STS had only a single endpoint (https://sts.amazonaws.com), but now, there is an endpoint in every AWS region. By bringing STS to a region geographically closer to you, your applications and services can call […]
