# Service discovery nmap -p 5357 <target>
It works in conjunction with , where UDP acts as the discovery mechanism, and TCP 5357 serves the actual device metadata over HTTP. 2. Reconnaissance and Enumeration
Port 5357 – WSDAPI (Web Services for Devices) - PentestPad
Disable or restrict inbound traffic on port 5357 using Windows Defender Firewall unless explicitly required for network discovery (e.g., dedicated print servers).
Enumeration is the first step when targeting port 5357. You must determine the exact service, operating system version, and configuration details. Nmap Scanning
Securing port 5357 involves reducing its network visibility and disabling unnecessary services. Firewall Filtering
Port 5357 (TCP) is the default endpoint utilized by the Microsoft . WSDAPI is an implementation of the WS-Discovery protocol, designed to enable Windows assets to discover and communicate with web-service-enabled hardware—primarily network printers, scanners, and file shares—without manual configuration or central directory servers.
