FWIW, I jail/chroot everything that connects to the net; e.g. browsers,
mail client, tor client, DNS server, nmap, snort, dhcpcd .....
everything.
What are you using to do your chrooting?
.r'
Can I recommend the excellent linux-vserver project? It's a bit more
heavyweight than you were looking for, but basically makes it super
simple to spin up what feel like fully virtualised machines.
Weight-wise it's somewhere between a full virtualisation solution and a
chroot (in fact it's kind of a wrapper around a chroot to make it feel
like a full machine instance). If you are really keen though you can
use the unification utility and effectively hard-link many jails
together which gives you a very, very lightweight way to run up many
instances of a process. Personally I wouldn't boot up a server without
using at least this...
If you just want to harden apache then also look at mod_security which
can give you a chroot and also quite a decent "software firewall" that
may well help. grsecurity (or other rbac) could additionally be used to
constrain the damage a cgi script could cause
Good luck
