[CentOS] iptables

I ran:

iptables -L

and see this:

Chain INPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere            state
RELATED,ESTABLISHED
ACCEPT     icmp --  anywhere             anywhere
ACCEPT     all  --  anywhere             anywhere
REJECT     all  --  anywhere             anywhere            reject-with
icmp-host-prohibited

Does the

REJECT all

over-ride the

ACCEPT all

Would "DROP all" be better so people banging on the ports don't see a reply?

I ran the gui tool to open ssh and it is in between ACCEPT all and REJECT
all.  Why does it work if there is a REJECT all after it?

Thanks,
