Key Concepts

What is Zero Trust?

Zero Trust Security Model: A security approach that assumes no implicit trust and requires continuous verification of all users, devices, and applications before granting access to resources.

Traditional Perimeter Security (Legacy):

Internet ← Firewall ← Internal Network (Trusted)
          ↓
    Once inside perimeter, access assumed

Zero Trust Model (Modern):

Every Access Request → Identity Verification
                    ↓
                Device Check
                    ↓
                Risk Assessment
                    ↓
                Conditional Access Policies
                    ↓
                    Grant (Limited, Monitored)

Why Zero Trust for Sovereign Clouds?

1. Enhanced Control:

Customer maintains explicit control over all access decisions
No implicit trust based on network location
Meets sovereign cloud requirement: “Customer control over access”

2. Regulatory Alignment:

FedRAMP mandates continuous monitoring and verification
GDPR requires granular access controls for data protection
HIPAA requires audit trails for all access
ITAR requires explicit user/device validation

3. Data Protection:

Access tied to business need and risk level
Sensitive data accessible only with highest verification
Compliance data stays within sovereign boundary

4. Operational Independence:

Works in disconnected environments (local verification)
Doesn’t depend on cloud provider infrastructure
Local enforcement of access policies

The Six Zero Trust Pillars

Pillar 1: Identity

Verify every user’s identity before access. Not based on network location or past authentication.

Key Controls:

Multi-factor authentication (MFA)
Passwordless authentication options
Conditional Access based on user risk
Just-in-time (JIT) access elevation

Pillar 2: Device

Ensure device health and compliance before allowing access to resources.

Key Controls:

Device compliance assessment
Health attestation
Device management enrollment
Conditional Access based on device status

Pillar 3: Network

Assume external network is untrusted. Implement microsegmentation and monitoring.

Key Controls:

Network microsegmentation
VPN or SD-WAN enforcement
Encrypted communications
Network monitoring and anomaly detection

Pillar 4: Application

Protect applications with authentication and authorization at application layer.

Key Controls:

Application-level authentication
API security and validation
Rate limiting and DDoS protection
Application monitoring and logging

Pillar 5: Data

Classify, encrypt, and protect sensitive data. Ensure access is logged and monitored.

Key Controls:

Data classification
Encryption in transit and at rest
Access logging and audit trails
Tokenization or redaction

Pillar 6: Infrastructure

Secure cloud infrastructure, container orchestration, and compute resources.

Key Controls:

Infrastructure access controls
Container security
Compute resource hardening
Infrastructure monitoring

Sovereign Cloud-Specific Requirements

Additional Sovereign Requirements

Standard Cloud Zero Trust:

Baseline security controls
Cloud provider managed infrastructure
Regional availability
Standard compliance frameworks

Sovereign Cloud Zero Trust:

Data Residency: All access must occur within sovereign boundary
Customer Control: Explicit customer control over all access policies
Government Compliance: FedRAMP, GDPR, ITAR, or other frameworks
Air-Gap Capable: Can operate in disconnected mode
Audit & Transparency: Complete audit trail accessible to customer
Local Enforcement: Access controls enforced locally, not cloud-dependent

Compliance Integration

FedRAMP Requirements:

Continuous monitoring of access (AC-2, AC-3)
Enforcement of user-based controls (AC-4)
Automated audit logging (AU-2, AU-12)

GDPR Requirements:

Data subject rights (access, deletion, portability)
Data Protection Impact Assessment (DPIA)
Encryption and pseudonymization
Access logging for compliance

HIPAA Requirements:

Access controls based on role and need
Audit controls for all access
Encryption of healthcare data
De-identification procedures

ITAR Requirements:

U.S. person verification
Controlled access to technical data
Storage within approved regions
Export control compliance
