Amen to that.  It's actually easier to sleep at night if you start off with the
assumption that every single packet is received by both the intended recipient
and the entity you *least* want getting said packet, and then designing your
communications accordingly..

Similarly for spoofed and MITM attacks - assume they WILL happen, and plan
accordingly.

Proper use of IPSec/OpenSSH/OpenSSL, with key/cert checking as appropriate,
goes a LONG way to raising the bar WAY up on the attacker.

Just don't forget about endpoint security - waay too many sites deploy OpenSSL
so credit card info can't be sniffed, and then leave the suckers in plaintext on the
web server. :)
