Open ports on your devices are a potential vulnerability that may let intruders gain remote access to your system and introduce malware that can grant them access to your data. We recommend checking the list of open ports in router settings and closing them unless they have been opened intentionally for specific well-understood purposes. If you are opening a port intentionally, make sure that you are using strong passwords and that software on the device that listens on that port is up to date.
