Internet TCP port 1900 is primarily used by the Simple Service Discovery Protocol (SSDP), which is a part of the Universal Plug and Play (UPnP) protocol standard. UPnP is commonly used in home networks to allow devices to discover each other's presence on the network and establish functional network services. Examples of software that use this port include media servers, game consoles, and other networked consumer electronics. It is also used by Microsoft's Windows operating system for network device discovery.
TCP port 1900 is associated with the Simple Service Discovery Protocol (SSDP), which is a network protocol for advertisement and discovery of network services and presence information. In the past, hackers have exploited this port to perform Distributed Denial of Service (DDoS) attacks. They send a large number of SSDP requests to a targeted server, overwhelming it and causing it to become unresponsive. Additionally, hackers have used this port to gain unauthorized access to devices on a network by exploiting vulnerabilities in the SSDP. This can lead to data breaches and other security incidents. Therefore, it is crucial to secure this port and monitor it for any suspicious activities.
