It is not recommended to disable network ports on your Windows Operating System as a general security measure. Instead, focus on implementing other security practices like using a firewall, keeping your system and applications updated, using strong passwords, and being cautious with email attachments and downloads.
Although disabling unnecessary network ports improves security, it is important to take care to avoid disrupting critical services. In general, only ports that are not actively used should be deactivated.
The commonly recommended methods are:
• Close unused ports: Disable ports that are not needed for your specific use case.
• Firewall configuration: Use a firewall to control incoming and outgoing traffic. Allow only the ports you need and block the rest.
• Remote Desktop and Administration: Disable remote desktop and administration ports (such as RDP - TCP port 3389) if they are not needed.
• File sharing: Disable the file sharing port if you do not need it. B. SMB (TCP ports 139, 445) or FTP (TCP ports 20, 21).
• Unused services: Disable unnecessary services and their associated ports. Review and update the list regularly based on your system's needs.
Always use caution when changing your system's network configuration, as disabling critical ports or services can affect functionality. Additionally, keeping your operating system and software up to date, using strong passwords, and practicing good security are important to your overall system security.
