Rule Text
The Palo Alto Networks security platform must deny network communications traffic by default and allow network communications traffic by exception (i.e., deny all, permit by exception).
Description
Discussion Text
A deny-all, permit-by-exception network communications traffic policy ensures that only those connections that are essential and approved are allowed. As a managed boundary interface between networks, the Palo Alto Networks security platform must block all inbound and outbound network traffic unless a policy filter is installed to explicitly allow it. The allow policy filters must comply with the site's security policy. A deny-all, permit–by-exception network communications traffic policy ensures that only those connections that are essential and approved are allowed.
By default, there are two security policies on the Palo Alto Networks firewall:
Allow traffic within the same zone (intra-zone)
Deny traffic from one zone to another zone (inter-zone).
No policy that circumvents the inter-zone policy is allowed. Traffic through the device is permitted by policies developed to allow only that specific traffic that the system or enclave requires.
