Is port 1900 (SSDP / UPnP) dangerous?

Port 1900 is classified as high risk. It is a common target for automated scanning and brute-force attacks. Restrict access to trusted IPs if exposure is necessary.

Should port 1900 be open on my firewall?

Port 1900 should only be open with strict firewall rules whitelisting trusted IP addresses. Enable rate limiting and intrusion detection systems.

What transport protocol does port 1900 use?

Port 1900 (SSDP / UPnP) uses the UDP transport protocol and falls under the System & Infrastructure category.

O que é a porta 1900?

Port 1900 is used by Simple Service Discovery Protocol (SSDP), the foundation for Universal Plug and Play (UPnP) device discovery. Smart TVs, routers, game consoles, and IoT devices use SSDP to advertise and discover services on local networks. This port has been exploited for amplification DDoS attacks when exposed to the internet.

Considerações de segurança

A porta 1900 (SSDP / UPnP) é classificada como alto risco. Esta porta é um alvo comum para varreduras automatizadas e ataques de força bruta. Se precisar expô-la, restrinja o acesso a endereços IP conhecidos.

Recomendação: Use regras de firewall para adicionar IPs confiáveis à lista de permissões. Ative a limitação de taxa e a detecção de intrusões.
