Some days ago I happened to open my event log and found lots of attacks
have been going on to my SQL server 2005. Maybe for some months. I have
been using firewall and Windows integrated authentication. The attacks
might be not quite successful. Anyway, I changed the SQL server port from
1433 to something another. Strikingly all the attacks have gone. Now I am
curious why they use port number 1433. Is there any reason to use the
port, benefit or something? Or is there any danger or caution to use
something other than 1433?
