*All services that are provided to the outside world should generate extensive logs.
 
*In this example, our FTP server caught a session of an attacker who is interested in publicly writable directories to upload illegal stuff (warez, audio, video, or even worse things) which can be downloaded afterwards.
 
*Many misconfigured web servers from Microsoft allow this. _vti_pvt is a directory which is used to administrate Frontpage uploads to a web server.
