Developed by **Farros FR** ([farrosfr.com](https://farrosfr.com)).\n\n## Project Overview\n\nThis suite provides a \"defense-in-depth\" approach to content filtering, tackling the problem at both the Operating System and Browser levels.\n\n### 1. OS-Level Hardening ([harden.ps1](https://github.com/farrosfr/noa/blob/main/harden.ps1))\n\nThe PowerShell script applies deep system changes to prevent filtering bypasses at the network level:\n\n- **System-wide DNS Enforcement:** Forces OpenDNS FamilyShield on all network adapters (IPv4 and IPv6).\n- **DNS over HTTPS (DoH) Lock:** Uses Registry Policies to force secure DoH templates for Chrome, Edge, Firefox, and Brave, preventing users from switching to unfiltered DNS within the browser.\n- **SafeSearch Enforcement:** Modifies the system `hosts` file to force Google, YouTube, Bing, and DuckDuckGo into SafeSearch mode.\n- **Firewall Evasion Blocking:** Implements outbound firewall rules to block known IP ranges used for content filtering bypasses.\n\n### 2. Browser-Level Protection (Extensions)\n\nAvailable for both **Chrome** and **Firefox**, these extensions provide real-time content inspection and redirection:\n\n- **Keyword Filtering:** Automatically detects and blocks access to sites based on custom keywords (e.g., piracy, adult content).\n- **Domain Whitelisting:** Easily exclude trusted domains like `farrosfr.com` or `google.com`.\n- **Dynamic Redirection:** Redirects blocked attempts to a specified educational or neutral URL.\n- **Settings Lock (Firefox):** Features a \"Challenge-Response\" lock mechanism. To modify settings, the user must manually type a randomized 15-character string, preventing impulsive changes to the filter.\n\n## Installation\n\n### Windows Hardening\n\n1. Open PowerShell as **Administrator**.\n2. Navigate to the project directory.\n3. Run the script:\n\n   ```powershell\n   .\\harden.ps1\n   ```\n\n4. Restart your browser for changes to take effect.\n\n### Browser Extensions\n\n#### Chrome\n\n1. Go to `chrome://extensions/`.\n2. Enable **Developer mode**.\n3. Click **Load unpacked** and select the `chrome/` folder.\n\n#### Firefox\n\n1. Go to `about:debugging#/runtime/this-firefox`.\n2. Click **Load Temporary Add-on...**.\n3. Select the `manifest.json` inside the `firefox/` folder.\n\n## Configuration\n\nThe Firefox extension includes a popup dashboard to:\n\n- Update blocked keywords.\n- Manage excluded domains.\n- Set the redirection target.\n- Toggle the **Settings Lock** for strict enforcement.\n\n## Credits\n\nDeveloped with 💻 by **Farros FR**.\n\n- **Website:** [https://farrosfr.com](https://farrosfr.com)\n- **GitHub:** [https://github.com/farrosfr/noa](https://github.com/farrosfr/noa)\n\n---\n*Disclaimer: Use this tool responsibly.
