# Firewall Rule Generator

## Overview

This skill provides automated assistance for firewall rule generator tasks within the GCP Skills domain.

## When to Use

This skill activates automatically when you:
- Mention "firewall rule generator" in your request
- Ask about firewall rule generator patterns or best practices
- Need help with google cloud platform skills covering compute, storage, bigquery, vertex ai, and gcp-specific services.

Overview

This skill automates generation of firewall rules and configuration patterns for Google Cloud Platform environments. It provides step-by-step guidance, produces production-ready rule snippets, and validates outputs against common standards. Use it to speed up firewall rule authoring while following GCP best practices.

How this skill works

The skill inspects your intent and environment context to propose firewall rules tailored to GCP resources (VPCs, instances, service tags, and target tags). It generates concrete configuration snippets (gcloud commands, Terraform blocks, or YAML) and runs basic validation checks for missing fields, CIDR correctness, and rule conflicts. It also offers recommended scopes, logging settings, and priority values to align with security policies.

When to use it

When you need to create or update firewall rules for GCP VPCs and compute resources
When you want production-ready gcloud or Terraform snippets for firewall policies
When validating existing rules for missing fields, overlapping CIDRs, or priority issues
When you need recommended rule scopes, logging, or deny/allow patterns
When you want step-by-step deployment guidance or rollback steps

Best practices

Use least-privilege rules: restrict source CIDRs and ports to the minimum required
Prefer service- or target-tags for broad groupings and avoid wide IP ranges
Set explicit priority and logging for rules that control critical access
Use deny rules sparingly and document exceptions with comments or labels
Keep rules modular and manage via IaC (Terraform or Deployment Manager) for reproducibility

Example use cases

Generate a secure SSH access rule limited to a corporate CIDR and with logging enabled
Create Terraform firewall resource blocks that enforce internal-only database access
Validate an existing rule set for overlapping priorities or unintended wide-open ports
Produce gcloud commands to add a deny rule for traffic to a sensitive subnet
Draft CI/CD automation steps to deploy and roll back firewall changes safely

FAQ

Can this skill output Terraform and gcloud examples?

Yes. It can generate gcloud commands, Terraform resources, or YAML snippets depending on your preferred workflow.

Does it check permissions or apply rules for me?

It validates configuration structure and common issues but does not apply changes; you must run the generated commands with appropriate credentials.
