# SOAR Implementation Workflow for Authorization Hierarchy Violation Detection

## Overview

This implementation focuses primarily on insider threats and privilege escalation within both SOAR environments and broader enterprise systems. The system is designed to detect:

1. Internal privilege escalation attempts
2. Unauthorized access pattern changes
3. Temporal anomalies in access behavior
4. Cross-system privilege abuse

## Environment Configuration

### Required API Keys and Credentials

1. **Splunk SOAR Configuration**
   - `SOAR_API_KEY`: Main API key for Splunk SOAR integration
   - `SOAR_BASE_URL`: Your Splunk SOAR instance URL
   - `SOAR_VERIFY_SSL`: SSL verification setting (true/false)

2. **Authentication System Integration**
   - `AUTH_SYSTEM_API_KEY`: API key for your authentication system
   - `AUTH_SYSTEM_URL`: Authentication system endpoint
   - `AUTH_SYSTEM_SECRET`: Shared secret for auth system communication

3. **Logging and Monitoring**
   - `LOG_LEVEL`: Logging level (DEBUG, INFO, WARNING, ERROR)
   - `MONITORING_API_KEY`: API key for monitoring system
   - `ALERT_WEBHOOK_URL`: Webhook URL for alert notifications

4. **Database Configuration**
   - `DB_CONNECTION_STRING`: Database connection string
   - `DB_USERNAME`: Database username
   - `DB_PASSWORD`: Database password
   - `DB_NAME`: Database name

### Environment Variable Setup

```bash
# Splunk SOAR Configuration
export SOAR_API_KEY="your_soar_api_key"
export SOAR_BASE_URL="https://your-soar-instance.splunk.com"
export SOAR_VERIFY_SSL="true"

# Authentication System
export AUTH_SYSTEM_API_KEY="your_auth_system_api_key"
export AUTH_SYSTEM_URL="https://auth.your-company.com"
export AUTH_SYSTEM_SECRET="your_auth_system_secret"

# Logging and Monitoring
export LOG_LEVEL="INFO"
export MONITORING_API_KEY="your_monitoring_api_key"
export ALERT_WEBHOOK_URL="https://alerts.your-company.com/webhook"

# Database
export DB_CONNECTION_STRING="postgresql://localhost:5432"
export DB_USERNAME="auth_monitor"
export DB_PASSWORD="your_secure_password"
export DB_NAME="auth_hierarchy_db"
```

## Implementation Steps

### 1. Initial Setup and Configuration

1. Configure environment variables:
   ```bash
   source /path/to/env_config.sh
   ```

2. Verify SOAR connectivity:
   ```python
   import phantom.app as phantom
   
   def verify_connectivity(self):
       try:
           response = phantom.requests.get(
               f"{self.SOAR_BASE_URL}/api/version",
               headers={"Authorization": f"Bearer {self.SOAR_API_KEY}"},
               verify=self.SOAR_VERIFY_SSL
           )
           return response.status_code == 200
       except Exception as e:
           return False
   ```

### 2. Insider Threat Detection Configuration

1. Define privilege levels and hierarchies:
   ```python
   PRIVILEGE_HIERARCHY = {
       "guest": {"level": 0, "can_escalate_to": ["user"]},
       "user": {"level": 1, "can_escalate_to": ["power_user"]},
       "power_user": {"level": 2, "can_escalate_to": ["admin"]},
       "admin": {"level": 3, "can_escalate_to": []}
   }
   ```

2. Configure detection thresholds:
   ```python
   DETECTION_CONFIG = {
       "rapid_escalation_window": 300,  # 5 minutes
       "max_failed_attempts": 3,
       "suspicious_time_windows": ["00:00", "06:00"],
       "max_privilege_jump": 2
   }
   ```

### 3. Integration Points

1. SOAR Playbook Integration:
   ```python
   def on_auth_violation(event):
       return {
           "status": "success",
           "summary": {
               "total_violations": len(event.violations),
               "severity": event.risk_score,
               "recommendation": event.mitigation_steps
           },
           "data": event.to_dict()
       }
   ```

2. Alert Configuration:
   ```python
   ALERT_CONFIG = {
       "low": {
           "threshold": 0.3,
           "response": "monitor",
           "notification": "log"
       },
       "medium": {
           "threshold": 0.6,
           "response": "investigate",
           "notification": "email"
       },
       "high": {
           "threshold": 0.8,
           "response": "block",
           "notification": "immediate"
       }
   }
   ```

### 4. Monitoring and Response

1. Configure monitoring intervals:
   ```python
   MONITORING_CONFIG = {
       "real_time_check_interval": 60,  # seconds
       "batch_analysis_interval": 3600,  # hourly
       "retention_period": 30  # days
   }
   ```

2. Setup response actions:
   ```python
   RESPONSE_ACTIONS = {
       "block_access": {
           "priority": "high",
           "requires_approval": True,
           "notification_channels": ["slack", "email"]
       },
       "increase_monitoring": {
           "priority": "medium",
           "requires_approval": False,
           "notification_channels": ["slack"]
       },
       "log_activity": {
           "priority": "low",
           "requires_approval": False,
           "notification_channels": ["log"]
       }
   }
   ```

## Scope of Detection

### Internal SOAR Environment
- Monitors access to SOAR playbooks and resources
- Tracks playbook execution permissions
- Monitors API key usage and scope
- Tracks automation rule modifications

### Enterprise-Wide Monitoring
- Active Directory privilege changes
- Cloud resource access patterns
- Database access levels
- Application role modifications

## Best Practices

1. **Regular Updates**
   - Update detection rules monthly
   - Review and adjust thresholds quarterly
   - Validate API keys every 90 days

2. **Maintenance**
   - Clean old detection data weekly
   - Verify integrations daily
   - Test response actions monthly

3. **Documentation**
   - Log all configuration changes
   - Document threshold adjustments
   - Maintain incident response procedures

## Testing and Validation

1. **Test Cases**
   ```python
   def test_privilege_escalation():
       # Test rapid escalation detection
       events = [
           {"user": "test_user", "action": "role_change", "from": "user", "to": "admin"},
           {"user": "test_user", "action": "access_attempt", "resource": "sensitive_data"}
       ]
       assert detect_violations(events).severity == "high"
   ```

2. **Validation Procedures**
   - Run test suite daily
   - Validate false positive rates weekly
   - Review detection accuracy monthly

## Troubleshooting

Common issues and solutions:

1. **API Connection Issues**
   ```bash
   # Test API connectivity
   curl -I -H "Authorization: Bearer $SOAR_API_KEY" $SOAR_BASE_URL/api/version
   ```

2. **Database Connectivity**
   ```bash
   # Test database connection
   psql -h localhost -U $DB_USERNAME -d $DB_NAME -c "SELECT version();"
   ```

3. **Log Analysis**
   ```bash
   # View recent logs
   tail -f /var/log/auth_hierarchy.log | grep "ERROR"
   ```
