security: shared vs. vps

i'm trying to decide between a shared server and a virtual private server. one issue is security. is either one more susceptible to intrusion than the other? this is assuming that in the shared server scenario, there are no rwx permissions for 'other' on my home directory (i.e. other users on the machine just can't cd into my area...).

a dedicated server is out of the question right now, moneywise.

specifically, i have a couple of sensitive files (being read by a cgi) that i wish to keep private. i can change the permissions of the files and their directory to 400. what else can i do to protect them?

thanks,

t
