## SAML Authentication
SAMLSecurity Assertion Markup Language是一种基于 XML 的开放标准身份认证协议用于在身份提供商IdP和服务提供商SP之间交换认证和授权数据。[[AWS-End-User-Computing]] 中的 [[AppStream-2]] 支持 SAML-based Authentication。
## How It Works in AWS EUC Context
SAML 认证在 AWS EUC 中的典型流程:
1. 用户向企业 IdP如 Azure AD / Microsoft Entra ID发起登录请求
2. IdP 验证用户身份,生成 SAML 断言
3. 断言转发给 AWS 服务AppStream 2.0 或 Workspaces
4. AWS 基于断言授予访问权限
## Benefits
| 优势 | 说明 |
|------|------|
| **增强安全性** | 集中化身份管理,支持 MFA |
| **简化用户体验** | 单点登录SSO无需单独记忆每个服务密码 |
| **合规性** | 集中审计用户访问行为 |
