Common use cases include allowing certain actions only from a specified, trusted range of IP addresses granting access only to specified AWS Regions and granting access only to resources with specific tags. IAM permissions policies support conditional access. For information about how to do this with Python, see How to Implement a General Solution for Federated API/CLI Access Using SAML 2.0. For information about how you can do this in Windows environments, see the blog post How to Set Up Federated API Access to AWS by Using Windows PowerShell. If you need to use federated authentication with MFA for the CLI on your own workstation, you’ll need to retrieve and present the SAML assertion token. In AWS Regions excluding AWS GovCloud (US), you can consider using the AWS CloudShell service, which is an interactive shell environment that runs in your web browser and uses the same authentication pipeline that you use to access the AWS Management Console-thus inheriting MFA enforcement from your SAML IdP. The AWS Single Sign-on (SSO) service is another way to implement federated authentication to the AWS APIs in regions where it is available. Instead, when you assume a role, it provides you with temporary security credentials for your role session.ĪWS accounts in all AWS Regions, including AWS GovCloud (US) Regions, have the same authentication options for IAM roles through identity federation with a SAML IdP. A role doesn’t have standard long-term credentials such as a password or access keys associated with it. ![]() The IdP used by our federal government customers should enforce usage of CAC/PIV to achieve MFA and be the sole means of access to AWS.įederated authentication uses SAML to assume an AWS Identity and Access Management (IAM) role for access to AWS resources. Many government customers achieve AWS federated authentication with Active Directory Federation Services (AD FS). MFA for the AWS APIsĪWS recommends that you use SAML and an IdP that enforces MFA as your means of granting users access to AWS. Workloads that sit behind an AWS Application Load Balancer can use the ALB to authenticate users using either Open ID Connect or SAML IdP that enforce MFA upstream. For this category, multi-factor authentication is still important, but will vary based on the specifics of the application architecture. There is also a third category of services where authentication occurs in AWS that is beyond the scope of this post: applications that you build on AWS that authenticate internal or external end users to those applications. Resources you launch that are running within your AWS VPC, which can include database engines or operating system environments such as Amazon Elastic Compute Cloud (Amazon EC2) instances, Amazon WorkSpaces, or Amazon AppStream 2.0.The AWS Command Line Interface (AWS CLI).AWS APIs, which include access through the following:.There are two categories we want to look at for authentication to AWS services: MikroTik CRS510-8XS-2XQ-IN 25GbE and 100GbE Switch Announced SAML is an industry-standard protocol and most IdPs support a range of authentication methods, so if you’re not using a PIV or CAC, the concepts will still work for your organization’s multi-factor authentication (MFA) requirements. Many federal customers use authentication factors on their Personal Identity Verification (PIV) or Common Access Cards (CAC) to authenticate to an existing enterprise identity service which can support Security Assertion Markup Language (SAML), which is then used to grant user access to AWS. This post focuses on the best-practices for enterprise authentication to AWS – specifically federated access via an existing enterprise identity provider (IdP). This post specifically focuses on how you can use AWS information security practices to help meet the requirement to “ establish multi-factor, risk-based authentication and conditional access across the enterprise” as it applies to your AWS environment. ![]() We recognize that government agencies have varying degrees of identity management and cloud maturity and that the requirement to implement multi-factor, risk-based authentication across an entire enterprise is a vast undertaking. This post is part of a series about how AWS can help your US federal agency meet the requirements of the President’s Executive Order on Improving the Nation’s Cybersecurity. ![]()
