However, FTP can become the bane of existence for the admins who must keep these services secure and operational. Poorly secured FTP services can often result in a successful attack on a server.

It can greatly decrease the chances of an attacker gaining access to a server via FTP exploits. Want evidence? The Red Hat, OpenBSD, and SuSE FTP sites all have one thing in common: They all run on VSFTP.
