Objects

An object is a container of information that you can use in one or more security policies. Objects make it easy to maintain policy consistency. You can create a single object, use it different policies, modify the object, and that change is propagated to every policy that uses the object. Without objects, you would need to modify all the policies, individually, that require the same change.

When you onboard a device, CDO recognizes all the objects used by that device, saves them, and lists them on the Objects page. From the Objects page, you can edit existing objects and create new ones to use in your security policies.

CDO calls an object used on multiple devices a shared object and identifies them in the Objects page with this badge .

Sometimes a shared object develops some "issue" and is no longer perfectly shared across multiple policies or devices:

• Duplicate objects are two or more objects on the same device with different names but the same values. These objects usually serve similar purposes and are used by different policies. Duplicate objects are identified by this issue icon:

• Inconsistent objects are objects on two or more devices with the same name but different values. Sometimes users create objects in different configurations with same name and content but over time the values of these objects diverge which creates the inconsistency. Inconsistent objects are identified by this issue icon:

• Unused objects are objects that exist in a device configuration but are not referenced by another object, an access-list, or a NAT rule. Unused objects are identified by this issue icon:

You can also create objects for immediate use in rules or policies. You can create an object that is unassociated with any rule or policy.

You can view the objects managed by CDO by navigating to the Objects menu or by viewing them in the details of a network policy.

CDO allows you to manage network and service objects across supported devices from one location. With CDO, you can manage objects in these ways:

• Search for and filter all your objects based on a variety of criteria.

• Find duplicate, unused, and inconsistent objects on your devices and consolidate, delete, or resolve those object issues.

• Find unassociated objects and delete them if they are unused.

• Discover shared objects that are common across devices.

• Evaluate the impact of changes to an object on a set of policies and devices before committing the change.

• Compare a set of objects and their relationships with different policies and devices.

• Capture objects in use by a device after it has been on-boarded to CDO.

If you have issues with creating, editing, or reading objects from an onboarded device, see Troubleshoot Cisco Defense Orchestrator for more information.
