# Securing Api Gateway With Aws Waf

## Overview

Cybersecurity skill for securing api gateway with aws waf. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "securing api gateway with aws waf"
- "Securing API Gateway endpoints with AWS WAF by configuring managed rule groups f"


- When deploying API Gateway endpoints that require protection against common web attacks
- When implementing rate limiting and throttling to prevent API abuse and DDoS attacks
- When building bot detection and mitigation for API endpoints exposed to the internet
- When compliance requires WAF protection for all public-facing API endpoints
- When customizing access controls based on IP reputation, geolocation, or request patterns

**Do not use** for network-level DDoS protection (use AWS Shield), for application logic vulnerabilities (use SAST/DAST tools), or for internal API security between microservices (use service mesh authentication and authorization).


## When NOT to Use

- When you lack proper authorization for testing
- For production systems without change management
- When the task requires legal or compliance expertise beyond technical scope


## Prerequisites

- AWS API Gateway (REST or HTTP API) deployed with public endpoints
- IAM permissions for `wafv2:*` and `apigateway:*` operations
- CloudWatch and S3 or Kinesis Firehose configured for WAF logging
- Understanding of the API's expected traffic patterns for rate limiting configuration
- IP reputation lists or threat intelligence feeds for custom IP blocking

## Workflow

```python
# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}
```

1. **Define Objectives** — Clarify the goals and scope for api gateway.
2. **Gather Resources** — Collect tools, data, and access needed for api gateway.
3. **Execute Process** — Carry out api gateway operations methodically.
4. **Verify Quality** — Check results against acceptance criteria.
5. **Document Outcomes** — Record findings, decisions, and next steps.

## Tools

- **aws waf** — Primary tool for this skill
- **Analysis Platform** — Data processing and visualization
- **Collaboration Tools** — Team coordination and knowledge sharing


## Process

1. **Design** — Define interface, identify patterns, plan implementation
1. **Implement** — Write code following existing conventions, add tests
1. **Verify** — Run tests, check integration, validate behavior

## Verification

- [ ] All api gateway procedures executed completely and documented
- [ ] Findings validated against multiple data sources
- [ ] False positives identified and filtered
- [ ] Results documented with evidence and timestamps
- [ ] Recommendations provided with risk-based prioritization

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
