 In the normal ACLs there is an implied "deny all" at the end.

i have never liked the ASA/security level approach that PIX uses--i
would rather not have implied policies.  i'm told you can assign
multiple interfaces the same security level, which will block the
implied policies for those interfaces, but i have not tried it and i
think it may not be supported (the documentation i've read doesn't
mention that case at all).

 According to Cisco, no traffic flows between two interfaces with the same
 level, while you can make it, I think it is not a supported config (I
didn't try it
 neither) nevertheless you can assign levels from 1-99 to the interfaces
connected to
 the Pix this is usually used to build a DMZ ......
