firewall

Just a little confused, normally a firewall applies to everything externally, and all internal servers (instances) can connect freely with each other.

With AWS, it comes with a firewall/security group.

Do these settings apply to each instance?

what about other customers, can there instances connect to my instances if I don't setup iptables on each instance?
