Programmatic Usage

package main

import (
    "fmt"
    "github.com/hallucinaut/zerotrust/pkg/validate"
    "github.com/hallucinaut/zerotrust/pkg/policy"
)

func main() {
    // Create validator
    validator := validate.NewValidator()
    
    // Configure zero trust
    config := &validate.Config{
        NetworkZeroTrust:    true,
        MultiFactorAuth:     true,
        RoleBasedAccess:     true,
        NetworkSegmentation: true,
        // ... other settings
    }
    
    // Assess posture
    assessment := validator.Assess(config)
    
    fmt.Printf("Score: %.0f%%\n", assessment.OverallScore*100)
    fmt.Printf("Status: %s\n", assessment.ComplianceStatus)
    
    // Create policy engine
    engine := policy.NewPolicyEngine()
    engine.AddPolicy(policy.GeneratePolicy("allow-admin", conditions, actions))
    
    // Evaluate request
    result := engine.Evaluate(request)
    fmt.Printf("Allowed: %v\n", result.Allowed)
}

🔍 Zero Trust Principles

1. Never Trust

Verify all traffic regardless of origin:

• No implicit trust for internal networks
• Verify all connections
• Encrypt all communications

2. Always Verify

Continuous authentication and authorization:

• Multi-factor authentication
• Continuous session validation
• Device health verification

3. Least Privilege

Minimum necessary access:

• Role-based access control
• Just-in-time access
• Purpose-limited permissions

4. Microsegmentation

Network segmentation:

• Zone-based architecture
• Service isolation
• VPC segmentation

5. Assume Breach

Limit damage from breaches:

• Incident response readiness
• Full telemetry
• Lateral movement prevention

📊 Assessment Levels

Score	Level	Status
90-100%	EXCELLENT	Fully compliant
70-89%	GOOD	Mostly compliant
50-69%	FAIR	Partial compliance
30-49%	POOR	Significant gaps
<30%	CRITICAL	Major remediation needed

🧪 Testing

# Run all tests
go test ./...

# Run with coverage
go test -cover ./...

# Run specific test
go test -v ./pkg/validate -run TestAssessZeroTrust

=== Zero Trust Assessment Report ===

Assessment Date: 2024-02-25 16:00:00
Overall Score: 85%
Compliance: COMPLIANT

Principle Checks:
  [1] ✓ never-trust (90%)
  [2] ✓ always-verify (85%)
  [3] ✓ least-privilege (80%)
  [4] ✓ microsegmentation (85%)
  [5] ✓ assume-breach (85%)

No recommendations - excellent posture!

🔒 Security Use Cases

• Zero Trust Implementation: Validate deployment progress
• Security Audits: Assess compliance with zero trust
• Risk Assessment: Identify security gaps
• Policy Management: Manage access policies
• Architecture Review: Validate zero trust design

🛡️ Best Practices

1. Implement all 5 principles before claiming zero trust
2. Continuous monitoring is essential
3. Regular assessments to maintain posture
4. Policy automation for scale
5. Incident response readiness
6. Device compliance checking
7. Least privilege enforcement
