Usually, routers can secure your network from external threats, especially when coupled with a strong firewall. And if your network is infected, remove router viruses or other malware immediately. Take steps to verify the safety of devices you introduce to your network. If a device is infected with malware, it could bypass security restrictions and infect other devices on your network.Īlthough potentially dangerous, the convenience of UPnP usually far outweighs the risk. If not, UPnP poses serious security risks, since it’s built into many new devices - even unverified ones connected to your network. UPnP is generally safe as long as your router is updated and secure. UPnP helps network devices connect to each other for easy discovery and quick communication. Before your next session, learn how to boost your gaming rig and discover if you should use a VPN for gaming. For optimal gaming, performance and security are also crucial. UPnP quickly links your console to your network so you can start playing immediately. Game consoles like Nintendo Switch need network access for online gaming. UPnP helps these new bits of technology connect to your TV or monitors with ease. Internet TV devices like Apple TV and Roku sticks have helped video streaming cut into the cable TV market. But with the convenience of synced IoT devices, comes a variety of new risks - it’s now more crucial than ever to protect your IoT devices. UPnP unites all these devices without any hassle. Whether in a smart home or at the office, IoT devices work best when interconnected with other devices nearby. Here are some of the most common uses of UPnP: As technology becomes more interconnected, the ability to quickly connect different apps and devices within the same network becomes more important. UPnP is used to conveniently connect different home devices - such as printers, gaming consoles, and smart home devices - in the same local network. Unlike port forwarding, UPnP network connections are automatic, so its security is arguably worse. Both protocols allow potentially infected devices to skip security procedures and connect directly to a network, potentially creating huge vulnerabilities. It allows apps and other devices on your network to open and close ports so they can connect with remote devices.Īlthough convenient and fast, UPnP and port forwarding can be dangerous. UPnP automates the port forwarding process. Port forwarding creates an association map between devices on a router’s local area network and its public, wide area network. Port forwarding, also called port mapping, establishes connections over the internet between devices on a home or local network and those on other private or public networks. And no matter if you use a public or private IP address, learn how to hide your IP address to keep your device from being identified on unsafe public Wi-Fi networks. Presentation: Sometimes a device can contain a URL that a client can access to get information or be used to change device settings.Ī lot of online troubleshooting begins with your IP address, so it’s helpful to know how to find your IP in case you need it. Here’s how a device uses UPnP to connect to a network:Īddressing: A new device joins a network and is assigned an IP address.ĭiscovery: The device shares its IP and other identifying information with other devices on the network.ĭescription: The device displays its unique services to the network.Ĭontrol: Other network devices (clients) start interacting with the new device.Įventing: Clients start subscribing “event notifications” to the new device, informing it when its services are needed. But under the hood, the process is more complicated. Most of the time, the way UPnP works is simple: you bring home a device, connect it to your local network, and it instantly connects to your other devices. It uses standard networking protocols - like TCP/IP, HTTP, XML, and SOAP - so that almost any device can automatically connect.Ĭommon devices that use UPnP include smartphones, printers, smart TVs, routers, and game consoles. Usually, devices connecting to a network require manual port forwarding, but UPnP simplifies network connectivity.
