A. Amazon Cognito
B. AWS IAM Identity Center (AWS Single Sign-On)
C. AWS Identity and Access Management (IAM)
D. AWS Directory Service for Microsoft Active Directory
Answer
B. AWS IAM Identity Center (AWS Single Sign-On)
Explanation
AWS IAM Identity Center (AWS Single Sign-On) is the AWS service that the company should use to meet the requirements for managing access and permissions for its third-party SaaS applications. AWS Single Sign-On is a cloud-based service that makes it easy to centrally manage single sign-on (SSO) access to multiple AWS accounts and business applications. You can use AWS Single Sign-On to enable your users to sign in to a user portal with their corporate credentials and access all their assigned AWS accounts and applications from one place.
AWS IAM Identity Center (formerly AWS Single Sign-On) is the ideal service for managing access and permissions for third-party Software-as-a-Service (SaaS) applications. It provides a centralized portal where end users can seamlessly access assigned AWS accounts and cloud applications. Here’s why it stands out:
Key Features of AWS IAM Identity Center
Centralized Access Management
IAM Identity Center allows you to manage user access across multiple AWS accounts and SaaS applications from one place. This reduces administrative overhead by eliminating the need to configure access separately in each account or application.
Single Sign-On (SSO)
Users can log in once using their existing credentials (e.g., from Microsoft Active Directory, Okta, or Azure AD) and gain access to all assigned accounts and applications without needing to remember multiple passwords.
Integration with SaaS Applications
IAM Identity Center supports integration with third-party SaaS applications via Security Assertion Markup Language (SAML) 2.0, enabling secure communication between the identity provider and service provider.
Customizable Permissions
Administrators can assign fine-grained permissions based on job roles or specific security requirements, ensuring that users only have access to what they need.
User Portal
End users are provided with a unified portal where they can view and access all their assigned AWS accounts and applications in one place, improving usability and productivity.
Enhanced Security
Features like multi-factor authentication (MFA) and attribute-based access control (ABAC) ensure robust security for user identities and resources.
Why Not the Other Options?
A. Amazon Cognito: While Amazon Cognito is excellent for building authentication into web and mobile apps, it does not offer centralized management of user access to multiple SaaS applications or AWS accounts.
C. AWS Identity and Access Management (IAM): IAM is designed for managing permissions within individual AWS accounts but lacks the centralized single sign-on capabilities required for managing third-party SaaS applications.
D. AWS Directory Service for Microsoft Active Directory: This service integrates with Microsoft AD for directory management but does not provide a user portal or SSO features for accessing multiple SaaS applications.
AWS IAM Identity Center is purpose-built for organizations looking to simplify user access management across multiple AWS accounts and third-party SaaS applications through a single, secure portal. It offers centralized control, seamless integration, and enhanced security features, making it the optimal choice in this scenario.
