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.
