The normal behaviour is "allow/deny anything specifically allowed/denied" then "deny anything not specified" for firewalls and similar devices. EDIT: Cisco firewalls have an implicit deny at the end of access list statements, but they're no longer the only game in town. Linux iptables depends on what the default policy for any given table is, and BSD pf depends on the admin assigning the first rule as "block all". This question is ambiguous in that the correct answer appears to ignore host-based firewalls which are ubiquitous now.
