Using Objects and Security Zones

Working with Security Zones

Chapter 4

you can expand each zone to view which interfaces on which devices belong to 

each zone.

All interfaces in a security zone must be of the same type, that is, 

all inline, passive, switched, or routed. Further, after you create a security zone, 

you cannot change the type of interfaces it contains.

You cannot delete a security zone that is in use. After you add or remove 

interfaces from a zone, you must reapply the device configuration to the devices 

where the interfaces reside. You must also reapply the access control and 

network discovery policies that use the zone.

To add a security zone:

: Admin/Access Admin/Network Admin

1. Select Objects > Object Management.

The Object Management page appears.

2. Select Security Zones.
