  backend services. Use when working with implementing api gateway security controls.

# Implementing Api Gateway Security Controls

## Overview

Cybersecurity skill for implementing api gateway security controls. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "implementing api gateway security controls"
- "Implements security controls at the API gateway layer including authentication e"


- Deploying a centralized authentication and authorization layer for microservice APIs
- Implementing rate limiting, throttling, and quota management across all API endpoints
- Configuring request/response validation against OpenAPI specifications at the gateway level
- Setting up TLS termination, mutual TLS, and certificate management for API traffic
- Integrating WAF rules with the API gateway to block injection, XSS, and known attack patterns

**Do not use** as the sole security layer. API gateways provide defense in depth but backend services must also validate authorization and input.


## 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

- API gateway platform selected and deployed (Kong, AWS API Gateway, Azure APIM, or Apigee)
- OpenAPI/Swagger specifications for all backend APIs
- TLS certificates for the gateway domain
- Identity provider (IdP) configured for OAuth2/OIDC (Okta, Auth0, Azure AD)
- Monitoring and logging infrastructure (CloudWatch, Datadog, ELK)
- Backend service endpoints registered and reachable from the gateway

## 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. **Assess Requirements** — Evaluate current environment and define api gateway security controls implementation requirements.
2. **Design Architecture** — Plan the api gateway security controls architecture, including components, integrations, and data flows.
3. **Configure Components** — Set up and configure each api gateway security controls component according to best practices.
4. **Test Integration** — Validate that all components work together. Run functional and security tests.
5. **Deploy to Production** — Roll out the implementation with monitoring and rollback capabilities.
6. **Validate and Document** — Verify the implementation meets requirements. Document configuration and runbooks.

## Tools

- **Configuration Management** — Infrastructure as code and automation
- **Monitoring Stack** — Observability and alerting
- **Documentation Platform** — Runbooks and architecture docs


## Process

1. **Reconnaissance** — Gather target information, identify attack surface, enumerate services
1. **Analysis/Exploitation** — Execute the technique, analyze results, document findings
1. **Reporting** — Document IOCs, write findings, provide remediation recommendations

## Verification

- [ ] All api gateway security controls 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. |
