## Definition
零信任安全模型Zero Trust是一种安全框架核心原则为"永不信任,始终验证"——不假设网络边界内的任何请求是安全的,要求每次访问都经过身份验证和授权。
## Core Principles
- 永不隐式信任:无论请求来自内网还是外网,都需验证
- 最小权限原则:仅授予完成任务的最低权限
- 持续验证:动态评估访问上下文(设备状态、位置、行为)
- 微分段网络:限制横向移动,即使边界被突破
## Cloud Implementation
- AWSIAM + Security Hub + GuardDuty
- AzureAzure AD + Microsoft Defender + Sentinel
- GCPGoogle IAM + Security Command Center
