Interface

Each interface can be assigned to a security zone and/or interface group. You then apply your security policy based on zones or groups. For example, you can assign the "inside" interface to the "inside" zone; and the "outside" interface to the "outside" zone. You can configure your access control policy to enable traffic to go from inside to outside, but not from outside to inside, for example. Some policies only support security zones, while other policies support zones and groups.

For more information about interface objects, see Security Zones and Interface Groups.

To add interface objects, see Create Security Zone and Interface Group Objects.
