content: Came to say this. Back when I did front line support,  I was always amazed by those who thought they could put a computer the public internet - base LAMP/WAMP configuration, no firewall - and then just never touch it again.  Why is my bandwidth bill so high/server slow?  Well...you have a 100Mb upload,  100% of which is being used to send UDP nonsense towards some server in Uzbekistan... What backups?  Sigh...
