# API Reference: Implementing Zero Trust in Cloud
|
|
|
|
## Libraries
|
|
|
|
### boto3 (AWS Zero Trust Checks)
|
|
- **Install**: `pip install boto3`
|
|
- IAM: `list_users()`, `list_mfa_devices()`, `get_account_summary()`
|
|
- EC2: `describe_instances()`, `describe_security_groups()`
|
|
- S3: `get_bucket_encryption()`, `get_public_access_block()`
|
|
- CloudTrail: `describe_trails()`, `get_trail_status()`
|
|
|
|
### azure-identity + azure-mgmt-authorization
|
|
- **Install**: `pip install azure-identity azure-mgmt-authorization`
|
|
- `AuthorizationManagementClient` -- RBAC role assignments
|
|
- `DefaultAzureCredential()` -- Auto-detect auth
|
|
|
|
### google-cloud-compute
|
|
- **Install**: `pip install google-cloud-compute`
|
|
- `FirewallsClient` -- VPC firewall rules audit
|
|
- `InstancesClient` -- VM network configuration
|
|
|
|
## Zero Trust Pillars (NIST SP 800-207)
|
|
|
|
| Pillar | Key Checks |
|
|
|--------|-----------|
|
|
| Identity | MFA enforcement, least privilege, conditional access |
|
|
| Device | Compliance policies, MDM, certificate identity |
|
|
| Network | Micro-segmentation, private endpoints, no public IPs |
|
|
| Application | OAuth2/OIDC, API gateway auth, no VPN dependency |
|
|
| Data | Encryption at rest/transit, DLP, classification |
|
|
| Visibility | Centralized logging, SIEM, UEBA, real-time alerts |
|
|
|
|
## AWS Zero Trust Services
|

|
|
|---------|-------------------|
|
|
| IAM Identity Center | Centralized identity and SSO |
|
|
| VPC PrivateLink | Private service connectivity |
|
|
| Verified Access | Identity-based application access |
|
|
| Security Hub | Continuous posture assessment |
|
|
| GuardDuty | Threat detection and monitoring |
|
|
| CloudTrail | API activity audit logging |
|
|
|
|
## Azure Zero Trust Services
|
|
|
|
| Service | Zero Trust Function |
|
|
|---------|-------------------|
|
|
| Entra ID Conditional Access | Policy-based access decisions |
|
|
| Azure Private Link | Private endpoint connectivity |
|
|
| Microsoft Defender for Cloud | CSPM and CWP |
|
|
| Azure Sentinel | SIEM and SOAR |
|
|
|
|
## GCP Zero Trust Services
|
|
|
|
| Service | Zero Trust Function |
|
|
|---------|-------------------|
|
|
| BeyondCorp Enterprise | Identity-Aware Proxy |
|
|
| VPC Service Controls | API-level perimeter |
|
|
| Binary Authorization | Container image trust |
|
|
| Security Command Center | Cloud posture management |
|
|
|
|
## Maturity Levels
|
|
- **Traditional**: Perimeter-based, VPN-dependent, implicit trust
|
|
- **Initial**: Some identity verification, partial segmentation
|
|
- **Advanced**: Continuous verification, micro-segmentation, encrypted everywhere
