## Security Best Practices

### Secure Development Lifecycle (SDLC)

```python theme={null}
class SecureSDLC:
    def __init__(self):
        self.security_gates = [
            'requirements_security_review',
            'design_security_review', 
            'code_security_scan',
            'penetration_testing',
            'security_acceptance_testing'
        ]
    
    def security_requirements_checklist(self):
        """Security requirements for new features."""
        return {
            'authentication': 'How will users be authenticated?',
            'authorization': 'What permissions are required?',

    def pre_deployment_security_checklist(self):
        """Security checklist before deployment."""
        checklist = [
            'security_scan_passed',

### Security Training & Awareness

    def assign_security_training(self, employee, role):
        """Assign role-appropriate security training."""
        
        required_modules = self.get_required_modules(role)
        
        for module in required_modules:
            SecurityTrainingAssignment.objects.create(
                employee=employee,

    def track_training_completion(self):
        """Track and report on security training completion."""
        
        completion_stats = SecurityTrainingAssignment.objects.values(
            'training_module'
        ).annotate(
            total_assigned=Count('id'),
            completed=Count('id', filter=Q(status='completed')),
            overdue=Count('id', filter=Q(
                status='assigned',
                due_date__lt=timezone.now()
            ))
        )
        
        return completion_stats
