      sudo ufw default deny incoming
      sudo ufw default allow outgoing
      sudo ufw enable

      Best Practices:

    20. Exclude high-usage folders (e.g., project directories) from real-time scans to avoid performance degradation.
    21. Update signatures daily via Windows Update (Windows) or `freshclam` (ClamAV).
    22. Monitor firewall logs for anomalous connections (e.g., unexpected outbound traffic to known malicious IPs).

      23. Network Security: VPN and Ad-Blocking for Public Wi-Fi

      Public networks (e.g., YorkU’s open Wi-Fi, coffee shop hotspots) are prime targets for man-in-the-middle (MITM) attacks, DNS spoofing, and traffic interception. A VPN with DNS leak protection and an ad-blocker creates a defense-in-depth strategy to obscure browsing activity and reduce tracking.

      Recommended Tools:

    23. VPN: ProtonVPN (free tier supports 3 devices) or WireGuard (self-hosted for advanced users).
    24. Ad-Blocker: uBlock Origin (browser extension) or Pi-hole (network-wide ad-blocking on Linux/macOS).
    25. DNS: Cloudflare (1.1.1.1) or Quad9 (9.9.9.9) to mitigate DNS-based attacks.

      26. Automating VPN Activation on Untrusted Networks:
      Use network scripts to detect public Wi-Fi and trigger VPN connections automatically.

      Windows (Batch/PowerShell):

      @echo off
      :: Check if connected to YorkU's public Wi-Fi (replace SSID with actual name)
      netsh wlan show interfaces | find "YorkU-Guest" >nul
      if %errorlevel% equ 0 (
      echo Connecting to ProtonVPN...
      "C:\Program Files\ProtonVPN\protonvpn.exe" -connect
      )

      macOS/Linux (Bash):

      #!/bin/bash

      Detect public Wi-Fi and connect to WireGuard

      PUBLIC_SSID="YorkU-Guest"
      if iwgetid -r | grep -q "$PUBLIC_SSID"; then
      echo "Public network detected. Activating WireGuard..."
      sudo wg-quick up wg0
      fi

      DNS Hardening (System-Wide):

      # macOS: Set Cloudflare DNS
      networksetup -setdnsservers Wi-Fi 1.1.1.1 1.0.0.1

      Linux: Edit /etc/resolv.conf (use systemd-resolved for persistence)

      sudo nano /etc/resolv.conf

      Add: nameserver 9.9.9.9

      Ad-Blocking Configuration:

    26. uBlock Origin: Enable EasyList, EasyPrivacy, and Malware Domains lists.
