R80 introduces a new policy concept called Layers to efficiently work with the rule base.
For Access Control Policy Two types of layers for maximum flexibility exists, inline layer and ordered layer. Where layers allow separating the security policy into multiple components. In this way creating better security and manageability. Support concurrent-admin's and segregation of duties, allow organizations to reuse of layer either as inline or ordered in multiple policy's to be more efficient.
- In Inline Layers only traffic matched/accepted on the parent rule will reach and be inspected by the inside layer rules.
- In Ordered Layers when an accept rule from the first layer is matched, the gateway goes over the rules in the next layer
For backward compatibility with pre-R80 gateway you will use ordered layers to manage the Firewall rule base and Application control rule base, where first layer needs to be Firewall layer and second layer needs to be Application control and URL Filtering layer.
During an upgrade from pre-R80 to R80 with gateways using policy packages that are using Firewall and Application control policy's, the existing policy will be separated to ordered Layer with Network Layer – Firewall policy rules as the first layer and Application Layer – Application control policy rules as the second layer.
Here is an example of traffic matching using
