Theres a great cisco document called "Essential IOS Consideration Every ISP
Should Consider" and covers unused services, NTP, security, routing
protocols, ACLs, etc.

You can find it here

        I personally don't like the idea of having to pull out the NVRAM. 
I would just configure a user mode password for the console and AUX ports.
Any way here are some awesome links on how to secure cisco IOS routers and a
good secure BGP config to boot as well. I would be VERY carefule with these
configs some of the things that it suggests may not fit your network.

If you have physical access you can still open the box pull the NVRAM
and your back in business.
in response to: What about physically disabling all the external ports ?

If you pull the NVRAM and place it in another router ? Otherwise I don't
understand after you physically disable (remove ) the external ports, how
you could work around it ?
