a secure base system

hi all,

i have a little question. i'm asked to set up a base system, which has to be secure. we want a system from which we can easily install a compromised system. so i had a few ideas to make it as secure and yet as usable as possible:

- use debian testing (stable is too old, unstable is ... well... you know ;))
- /var and /tmp mounted nosuid and noexec
- grsec kernel
- use lvm (so you don't need to worry about the sizes af the partitions)
- remote logging to our logging server
- all this in hardware raid 1 for easy transfer to other systems
- iptables with all connections refused (you need physical access to do something)
- maybe allow ssh (no root logins)?

==> is this ok, too paranoia or is there somenting i'm missing, and cound it be even more safe?

how about a compiler? normally, all soft on it is compiled by hand, but it is also "necessary" for a local exploit.

any ideas? remarks?

tnx in advance
