There are few reasons to have syslog listening on that port: There might be some services running on you host (not that I know any) that try to write to the loopback interface rather than a UNIX socket. In that case you can force syslog only to bind to the loopback interface adding "-b localhost". Also, you should have your local firewall block incoming traffic.
