Well, I guess that pretty much depends on how you define "so secure". If 
that means 100% secure, then you have a problem. Defining how difficult it 
is to break SSH also depends largly on you knowledge of 
computer networking, especially cryptography and how SSH is implemented in 
FreeBSD. I guess you should do a google search for all of this(Bruce 
Schneier has a relatively good book on Cryptography and Hill on Coding 
Theory) but for remote control of your computer I would prefer keeping 
port 22 and SSH because it is relatively secure in the end.
