Custom Patterns

DjangoAPI Guard allows you to add custom patterns for detecting suspicious activity.

---

Adding Custom Patterns

from djangoapi_guard import SusPatternsManager

def setup_patterns():
    SusPatternsManager.add_pattern(r"malicious_pattern.*", custom=True)

---

Pattern Types

# Custom XSS pattern
SusPatternsManager.add_pattern(r"<script\s*src=.*>", custom=True)

# Custom SQL injection pattern
SusPatternsManager.add_pattern(r";\s*DROP\s+TABLE", custom=True)

# Custom file path pattern
SusPatternsManager.add_pattern(r"\.\.\/.*\/etc\/passwd", custom=True)

---

Managing Patterns

# Remove a custom pattern
success = SusPatternsManager.remove_pattern(r"malicious_pattern.*", custom=True)

# Get all patterns
all_patterns = SusPatternsManager.get_all_patterns()

# Get only custom patterns
custom_patterns = SusPatternsManager.get_custom_patterns()

---

Pattern Testing

from guard_core.sync.utils import detect_penetration_attempt
from django.http import JsonResponse

def test_patterns(request):
    is_suspicious, trigger_info = detect_penetration_attempt(request)
    return JsonResponse({
        "suspicious": is_suspicious,
        "trigger_info": trigger_info,
    })
