# API Reference: Analyzing API Gateway Access Logs
|
|
|
|
## AWS API Gateway Log Fields
|
|
|
|
```json
|
|
{
|
|
"requestId": "abc-123",
|
|
"ip": "203.0.113.50",
|
|
"httpMethod": "GET",
|
|
"resourcePath": "/api/users/{id}",
|
|
"status": 200,
|
|
"requestTime": "2025-03-15T14:00:00Z",
|
|
"responseLength": 1024
|
|
}
|
|
```
|
|
|
|
## Pandas Log Analysis
|
|
|
|
```python
|
|
import pandas as pd
|
|
|
|
df = pd.read_json("access_logs.json", lines=True)
|
|
|
|
# BOLA detection
|
|
df.groupby("user_id")["resource_id"].nunique()
|
|
|
|
# Auth failure surge
|
|
df[df["status_code"] == 401].groupby("source_ip").size()
|
|
|
|
# Request velocity
|
|
df.set_index("timestamp").resample("1min").size()
|
|
```
|
|
|
|
## OWASP API Top 10 Patterns
|
|
|
|
| Risk | Detection Pattern |
|
|
|------|-------------------|
|
|
| BOLA (API1) | User accessing > 50 unique resource IDs |
|
|
| Broken Auth (API2) | > 100 401/403 from single IP |
|
|
| Excessive Data (API3) | Response size > 10x average |
|
|
| Rate Limit (API4) | > 100 req/min from single IP |
|
|
| BFLA (API5) | DELETE/PUT on read-only endpoints |
|
|
| Injection (API8) | SQL/NoSQL patterns in params |
|
|
|
|
## Injection Regex Patterns
|
|
|
|
```python
|
|
sql = r"union\s+select|drop\s+table|'\s*or\s+'1'"
|
|
nosql = r"\$ne|\$gt|\$regex|\$where"
|
|
xss = r"<script|javascript:|onerror="
|
|
path_traversal = r"\.\./\.\./|/etc/passwd"
|
|
```
