mDNS, SSDP and WS-Discovery: What They Reveal About Devices
Local discovery protocols can reveal names, services, printers, media devices, management interfaces and other context that ordinary ping sweeps may miss.

mDNS advertises local names and services
Multicast DNS is commonly used for service discovery on local networks. Devices may advertise hostnames and service types without a central DNS server.
SSDP and UPnP expose service descriptions
SSDP can announce devices and URLs describing capabilities. It is common in consumer, media and some appliance environments.
WS-Discovery is common in Windows-adjacent environments
Printers, scanners and other devices may use WS-Discovery for local discovery and setup.
Combine protocols instead of trusting one signal
A device that ignores ICMP may still advertise through mDNS or SSDP. Scantide Auditor can use multiple discovery signals during authorized local reviews to build stronger evidence.

Field experience from the archive
Historical source · JufCorp: Securing Windows Server with a baseline security11. Disable any unused services and network protocols. They can be a point of entry and for the unused network protocols, you bascially fill your local network with useless chatter that comsume bandwidth. This also goes for workstations and printers and so on.
Historical source · JufCorp: Securing your server environment - Part III - Operating systemsGo through all services started and make sure the ones they don't use SYSTEM accounts etc unless they need to. Should the service running contain a bug and someone manages to exploit that bug, they've got SYSTEM access to your server, meaning the entire server. If you have service-users running services instead and those user are locked down, you'll minimize the damage at least When setting up the server, make sure to disable services not in use. Both from a security point of view and for performance. Windows for instance starts quite a few services that you probably don't use nor need.
In many environments, local firewalls are disabled out of pure laziness. "We can't be bothered troubleshooting why SQL traffic doesn't work .." Have local firewalls enabled , enable logging so you can easily find what's going on. If you're in a shared environment you'll also get alerted about noisy neighbors . Local firewalls also enables you to utilize a brute force prevention software and have those attacks mitigated, no matter where they come from. If you want, I'll happily help you out with getting a brute force prevention software in place.

Printer Security: Printers store documents, have web interfaces, and can be entry points. Update firmware, disable unnecessary services, use authentication.
