n00b response here

I thought using ACLs or otherwise protecting the BGP endpoint was best 
practice.  Thus it's really hard to even try break an MD5 protected BGP 
session if you can't even establish the TCP connection.

Everything that I've seen or set up had an ACL to only allow the peer(s) 
to be able to connect to (from memory) TCP port 179.

Is there something that I've missed the boat on?
