Configuring Objects
Objects are reusable components for use in your configuration. They can be defined and used in adaptive
security appliance configurations in the place of inline IP addresses. Objects make it easy to maintain
your configurations because you can modify an object in one place and have it be reflected in all other
places that are referencing it. Without objects you would have to modify the parameters for every feature
when required, instead of just once. For example, if a network object defines an IP address and subnet
mask, and you want to change the address, you only need to change it in the object definition, not in
every feature that refers to that IP address.
