Configuration Of Zone-Based Firewall on Cisco IOS Router with 3 Zones #ZoneBasedFirewall #CiscoIOSRouter #NetworkSecurity Zone-Based Policy Firewall (ZBPF) (Zone Based Firewall) is the successor of Cisco IOS Legacy Firewall called (CBAC) Context-Based Access Control. Concept of ZBPF is zone, which groups different interfaces sharing the same security attributes or the same level of trust. In Zone-based firewall, logical zones are created. A zone is assigned to an interface. By default, traffic from one zone to another is not allowed. After creating a zone, a class-map policy is made which will identify the type of traffic, like ICMP, on which the policies will be applied.
