Intro To Cisco Zone Based Firewalls #CCNA #CCNAsecuirty #firewall

With a zone-based firewall solution, zones are created for each part of the network that required different access/traffic control policies. ... These zone-pairs are unidirectional and are configured with a specific traffic policy that is used when traffic passes from the source zone to destination zone.

Security zones are a logical way to group physical and virtual interfaces on the firewall to control and log the traffic that traverses specific interfaces on your network. An interface on the firewall must be assigned to a security zone before the interface can process traffic.
