They talk about iACL and tACL design philosophy.

What traffic you should permit/deny on your network is, of course, 
situationally-specific.  Depends on what kind of network it is, what 
servers/services/applications/users you have, et. al.  You may need one 
set of ACLs at the peering/transit edge, and other, more specific ACLs, 
at the IDC distribution gateway, customer aggregation gateway, et. al.
