Managing Firewall Settings to Block Remote Access

Firewalls serve as a critical line of defense by controlling incoming and outgoing network traffic. Configuring your firewall to block remote access ports can significantly reduce exposure.

Key ports to consider blocking:

– **TCP 3389** — used by Windows Remote Desktop.
– **TCP 5900-5902** — used by VNC and Screen Sharing.
– **TCP 22** — used by SSH (common on macOS and Linux).

Most operating systems include built-in firewalls that can be configured as follows:

**Windows Firewall Configuration:**

  • Open **Windows Defender Firewall**.
  • Select **Advanced Settings**.
  • Create **Inbound Rules** to block the ports mentioned above.
  • Specify the action to **Block the connection**.

**macOS Firewall Configuration:**

  • Open **System Preferences** > **Security & Privacy** > Firewall.
  • Turn on the firewall and enable Firewall Options.
  • Add apps or services to block incoming connections.
Port Service Purpose Recommended Action
