Failed FTP login signature

["Atkins, Dwane P" <ATKINSD () uthscsa edu>]

In an attempt to possible thwart attacks prior to arriving a the
desktop, we are looking for a signature that would alert us as to when
someone is trying to FTP or SSH into a system on our network.  I am
thinking that if someone has typed in 5 or 6 passwords and has not
connected, then they certainly do not have a need to be there.

 

Does anyone out there have a signature for this type of incident?

 

We would probably be looking at Telnet, SSH, FTP and possible HTTP.


Thanks 


Dwane
