What default firewall/IDS does Debian come with following an initial install?

Note: during install I selected all major components and did not include any additional
packages wile installer was running aptitude.

AFAIK there is no default firewall.

I always recommend shorewall because it is very powerful, but pretty
easy to setup. If you prefer a graphical one than firestarter is also a
good choice.

Andrei
