Scope of Guidelines

These guidelines apply to:

  • All users of HawkEye software
  • Security assessments using HawkEye
  • Organizations deploying HawkEye
  • Third-party security consultants
  • Internal security teams

Responsibility Statement

Users of HawkEye are solely responsible for ensuring their activities comply with:

  • Applicable laws and regulations

Legal and Ethical Framework

Legal Compliance

Authorization Requirements

CRITICAL: Never use HawkEye without explicit written authorization.

Required Documentation:

  • Written authorization from network owner
  • Scope definition and limitations
  • Time window specifications
  • Emergency contact information
  • Incident response procedures

Example Authorization Template:

SECURITY ASSESSMENT AUTHORIZATION

  4. Responsible Disclosure: Report vulnerabilities appropriately

Professional Standards

  • Follow industry codes of ethics (ISC2, ISACA, etc.)
  • Maintain professional certifications and training
  • Participate in responsible security community
  • Contribute to security knowledge sharing

Authorization Requirements

Pre-Assessment Authorization

Minimum Required Elements

  1. Written Permission: Signed authorization from authorized representative
  2. Scope Definition: Clear boundaries of assessment activities
  3. Time Constraints: Specific start and end times
  4. Contact Information: 24/7 emergency contacts
  5. Escalation Procedures: Clear incident response chain

Authorization Verification

# Verify authorization before each scan
echo "Authorization verified for: $TARGET_NETWORK"
echo "Authorized by: $AUTHORIZED_BY"
echo "Valid until: $EXPIRATION_DATE"
echo "Emergency contact: $EMERGENCY_CONTACT"

# Log authorization details
python application.py audit-log \
    --action "scan_authorized" \
    --target "$TARGET_NETWORK" \
    --authorized-by "$AUTHORIZED_BY" \
    --expires "$EXPIRATION_DATE"

Scope Management

Defining Boundaries

Include in Scope:

  • Specific IP ranges or CIDR blocks
  • Named systems and applications
  • Specific ports and services
  • Time windows for testing

Exclude from Scope:

  • Production critical systems
  • Third-party hosted services
  • Personal devices
  • Out-of-scope network segments

Scope Validation

# Validate target is within authorized scope
python application.py validate-scope \
    --target 192.168.1.100 \
    --authorization-file auth.json

# Example authorization file
cat > auth.json << 'EOF'
{
    "authorized_ranges": [
        "192.168.1.0/24",
        "10.0.1.0/24"
    ],
    "excluded_ranges": [
        "192.168.1.1",
        "192.168.1.254"
    ],
    "authorized_by": "John Smith, CISO",
    "valid_until": "YYYY-MM-DDT23:59:59Z"
}
EOF

Operational Security

Secure Tool Deployment

Environment Hardening

  1. Isolated Environment: Run HawkEye from dedicated security workstation
  2. Network Segmentation: Use separate network segment for security testing
  3. Access Controls: Implement strong authentication and authorization
  4. Audit Logging: Enable comprehensive activity logging

Configuration Security

# secure_config.yaml
security:
  audit_logging: true
  encrypted_storage: true
  access_control: strict
  network_isolation: true

logging:
  level: INFO
  audit_trail: true
  encryption: true
  retention_days: 90

authentication:
  require_2fa: true
  session_timeout: 3600
  max_failed_attempts: 3

Credential Management

Tool Credentials

  • No Hardcoded Credentials: Never embed credentials in configurations
  • Secure Storage: Use encrypted credential stores
  • Rotation Policy: Regularly rotate service accounts
  • Least Privilege: Grant minimum required permissions

Target System Access

  • Read-Only Access: Use read-only credentials when possible
  • Temporary Accounts: Create temporary accounts for assessments
  • Account Monitoring: Monitor account usage during assessments
  • Cleanup Procedures: Remove temporary accounts after completion

Data Protection

Scan Data Security

Data Classification

  • Highly Sensitive: Vulnerability details, system configurations
  • Sensitive: Network topology, service inventories
  • Internal: Scan metadata, timing information
  • Public: General methodology, tool information

Protection Measures

# Encrypt scan results
gpg --cipher-algo AES256 --compress-algo 1 --symmetric \
    --output scan_results.json.gpg scan_results.json

# Secure file permissions
chmod 600 scan_results.json.gpg
chown security:security scan_results.json.gpg

# Secure deletion of unencrypted data
shred -vfz -n 3 scan_results.json

Data Retention

Retention Policies

  • Active Assessments: Retain during assessment period
  • Completed Assessments: Retain per organizational policy (typically 1-3 years)
  • Compliance Requirements: Follow regulatory retention requirements
  • Secure Disposal: Use secure deletion methods

Data Lifecycle Management

# Automated data lifecycle management
cat > data_lifecycle.sh << 'EOF'
#!/bin/bash

# Archive old scan data
find /scan_results -name "*.json" -mtime +30 -exec gzip {} \;

# Move archived data to secure storage
find /scan_results -name "*.gz" -mtime +90 -exec mv {} /secure_archive/ \;

# Securely delete expired data
find /secure_archive -name "*.gz" -mtime +1095 -exec shred -vfz -n 3 {} \;
EOF

Privacy Protection

Personal Data Handling

  • Minimize Collection: Collect only necessary information
  • Data Anonymization: Remove or mask personal identifiers
  • Access Controls: Restrict access to authorized personnel
  • Consent Management: Obtain consent where required

GDPR Compliance

# Example privacy protection implementation
def sanitize_scan_results(results):
    """Remove or mask personal data from scan results"""
    sanitized = results.copy()
    
    # Remove personal identifiers
    if 'user_accounts' in sanitized:
        sanitized['user_accounts'] = ['[REDACTED]'] * len(sanitized['user_accounts'])
    
    # Mask IP addresses if required
    if 'internal_ips' in sanitized:
        sanitized['internal_ips'] = [mask_ip(ip) for ip in sanitized['internal_ips']]
    
    return sanitized

Network Courtesy

Rate Limiting

Conservative Defaults

# Conservative scanning configuration
scanning:
  default_threads: 10
  default_timeout: 10
  rate_limit: 25
  retry_attempts: 2
  delay_between_requests: 100

network_courtesy:
  respect_robots_txt: true
  avoid_peak_hours: true
  monitor_impact: true
  emergency_stop: true

Dynamic Rate Adjustment

# Monitor network impact and adjust rates
def monitor_network_impact():
    """Monitor network performance and adjust scanning rates"""
    response_times = measure_response_times()
    error_rates = measure_error_rates()
    
    if response_times > threshold or error_rates > threshold:
        reduce_scan_rate()
        log_impact_detected()
    
    return current_scan_rate

Impact Minimization

Timing Considerations

  • Avoid Peak Hours: Schedule scans during maintenance windows
  • Business Hours: Respect business operational hours
  • Time Zones: Consider global operations and time zones
  • Maintenance Windows: Coordinate with system maintenance

Resource Management

# Resource-conscious scanning
python application.py scan \
    --target 192.168.1.0/24 \
    --threads 5 \
    --rate-limit 10 \
    --timeout 15 \
    --nice-priority \
    --monitor-impact

Incident Response

Emergency Procedures

Immediate Response

  1. Stop Scanning: Immediately halt all scanning activities
  2. Assess Impact: Determine scope and severity of incident
  3. Notify Stakeholders: Contact emergency contacts and management
  4. Document Incident: Record all relevant details
  5. Preserve Evidence: Maintain logs and scan data

Emergency Stop Procedures

# Emergency stop all HawkEye processes
pkill -f "python.*application.py"

# Log emergency stop
echo "$(date): EMERGENCY STOP - All scanning halted" >> emergency.log

# Notify emergency contacts
python application.py emergency-notify \
    --incident "Scanning halted due to network impact" \
    --severity "HIGH"
