1.2.1.c: Deny All Other Traffic
Examine all "deny" rules to verify that all other inbound and outbound traffic is explicitly denied


Examination of all inbound and outbound "deny" rules to make sure that there is a firewall rule to deny traffic for undocumented inbound and outbound connections can help to close gaps that would allow unwanted and bad traffic. Using an explicit "deny all" or an implicit deny after allow statement can help to close such gaps.
