implementing-zero-trust-with-beyondcorp
Helps your agent configure BeyondCorp for application access based on identity and device posture.
What it does
This tool helps set up Google's BeyondCorp security system. It works without needing private networks (VPNs), checking who you are and if your device is secure for every access. The goal is to protect your applications and data.
When to use it
- ✓When you want to protect your applications without using VPNs.
- ✓When setting up access rules based on user identity and device status.
- ✓To ensure your systems' security meets compliance requirements.
Example of what to ask your AI
“Set up BeyondCorp to protect my web application.”

How it works
The tool configures Google's 'Identity-Aware Proxy' (IAP) to check each access. It creates rules that define who can access what, based on user identity and device characteristics (like operating system and encryption status).
Installation

Implementing Zero Trust with BeyondCorp
Overview
Google BeyondCorp Enterprise implements the zero trust security model by eliminating the concept of a trusted network perimeter. Instead of relying on VPNs and network location, BeyondCorp authenticates and authorizes every request based on user identity, device posture, and contextual attributes. Identity-Aware Proxy (IAP) serves as the enforcement point, intercepting all requests to protected resources and evaluating them against Access Context Manager policies. This skill covers configuring IAP for web applications, defining access levels based on device trust and network attributes, and auditing access policies for compliance.
When to Use
- When deploying or configuring implementing zero trust with beyondcorp capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation
Prerequisites
- Google Cloud project with BeyondCorp Enterprise license
- IAP API enabled (iap.googleapis.com)
- Access Context Manager API enabled (accesscontextmanager.googleapis.com)
- GCP resources to protect (Compute Engine, App Engine, or GKE services)
- Endpoint Verification deployed on managed devices
- Python 3.9+ with google-cloud-iap library
Steps
Step 1: Enable IAP on Target Resources
Configure Identity-Aware Proxy on Compute Engine, App Engine, or HTTPS load balancer backends.
Step 2: Define Access Levels
Create Access Context Manager access levels based on IP ranges, device attributes (OS version, encryption, screen lock), and geographic location.
Step 3: Bind Access Policies
Apply access levels as IAP conditions to enforce context-aware access decisions on protected resources.
Step 4: Audit and Monitor
Query IAP audit logs, verify policy enforcement, and identify gaps in zero trust coverage.
Expected Output
JSON report containing IAP-protected resources, access level definitions, policy binding audit results, and zero trust coverage metrics.
FAQ
What is 'Zero Trust'?
It's a security model that assumes nothing is trusted by default. Every access attempt, even from within the network, needs to be verified and authorized.
What is 'Identity-Aware Proxy' (IAP)?
It's a Google tool that acts like a digital gatekeeper. It sits in front of your applications and verifies the identity and permissions of those trying to access them before allowing entry.
Do I need a Google Cloud project?
Yes, you need a Google Cloud project with the BeyondCorp Enterprise license active and the necessary APIs enabled.
