Greetings Listers, I've taken up an interest in firewalls & setup up Windows Firewall on my home PC. Over the course of analyzing the logs, I notice there's a lot of traffic on TCP & UDP port 1900. Many online forums say that is a security threat. Should I disable the SSDP service on my home network? Also, is it advisable to leave the port open on corporate networks? Warm regards, Michael Bullut. --- *Cell:* *+254 723 393 114. **Skype Name:* *Michael Bullut.* ***Twitter:** @Kipsang <http://twitter.com/Kipsang/> * *Blog: http://www.kipsang.com/* *E-mail:* *main@kipsang.com* * * *---*
