🔐 BlueWall – Firewall Auditor

BlueWall is a firewall auditing tool for pfSense and OPNsense configurations. It parses XML exports, identifies strengths and weaknesses, simulates attack scenarios, and provides compliance scoring against frameworks like NIST CSF, CIS Controls, ISO 27001, PCI DSS, SOC 2, and COBIT 2019.

✨ Features

• ✅ Parse pfSense/OPNsense XML configs (rules, NAT, aliases, schedules).
• ✅ Detect firewall strengths & weaknesses.
• ✅ Simulate attack & exfiltration scenarios (e.g., brute force, reverse shell).
• ✅ Generate a security score (1–10) with details.
• ✅ Map findings to major security frameworks.
• ✅ Export interactive HTML reports with graphs & charts.

📦 Installation

From RubyGems

gem install bluewall

From Source

git clone https://github.com/yourusername/bluewall.git
cd bluewall
bundle install

🚀 Usage

Export your firewall configuration (config.xml) from pfSense/OPNsense, then run:

bluewall config.xml

You’ll get:

• Console summary (strengths, weaknesses, score).
• Optional detailed compliance breakdown.
• Optional interactive HTML report.

--- BlueWall Audit Report ---
Firewall Type: PFSENSE_LIKE
Strengths:
  - Explicit 'DENY all' inbound rule on WAN detected
Weaknesses:
  - Rule allows SSH from any source on WAN (**Critical risk!**)
Overall Security Score (1–10): 5.4

🎯 Compliance Mapping

BlueWall maps findings against:

• NIST Cybersecurity Framework (CSF)
• CIS Controls
• ISO/IEC 27001
• PCI DSS
• SOC 2
• COBIT 2019

🛣️ Roadmap & Future Features

• 🔄 Live Firewall API Support – direct audits via pfSense/OPNsense API.
• 📡 SIEM / Log Integration – export to Splunk, ELK, Graylog.
• 🧪 Custom Attack Profiles – extend simulations with YAML/JSON configs.
• 📜 JSON/Markdown Reports – lightweight and developer-friendly outputs.
• 🌐 Web Dashboard – interactive UI for reports and history.
• 🔒 More Frameworks – add HIPAA, GDPR, FedRAMP mappings.
• 📊 Asset-aware Risk Scoring – weight rules by criticality.
• 🧩 Plugin System – allow custom rules & attack modules.
