# Configuring Identity Aware Proxy With Google Iap

## Overview

Cybersecurity skill for configuring identity aware proxy with google iap. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "configuring identity aware proxy with google iap"
- "Configuring Google Cloud Identity-Aware Proxy (IAP) to enforce per-request ident"


- When protecting Google Cloud applications (App Engine, Cloud Run, GKE, Compute Engine) with identity-based access
- When implementing context-aware access requiring device posture and location verification
- When providing secure access to internal tools without VPN or public IP exposure
- When needing per-request authentication and authorization for web applications and TCP services
- When configuring programmatic access to IAP-protected resources using service accounts

**Do not use** for non-HTTP applications that cannot be placed behind an HTTPS load balancer, for public-facing applications that need unauthenticated access, or when applications handle their own authentication and IAP would conflict with existing auth flows.


## 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

- Google Cloud project with billing enabled
- IAP API enabled (`gcloud services enable iap.googleapis.com`)
- Application deployed behind HTTPS Load Balancer, App Engine, or Cloud Run
- Cloud Identity or Google Workspace for user management
- Access Context Manager API enabled for access levels
- OAuth consent screen configured for the project

## 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 identity aware proxy.
2. **Gather Resources** — Collect tools, data, and access needed for identity aware proxy.
3. **Execute Process** — Carry out identity aware proxy operations methodically.
4. **Verify Quality** — Check results against acceptance criteria.
5. **Document Outcomes** — Record findings, decisions, and next steps.

## Tools

- **google iap** — 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 identity aware proxy 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. |
