The Device Manager pane is used to install policy packages to devices. When ADOMs are enabled, the Device Manager pane is used to install policy packages to the devices in an ADOM.
Policy packages can include header policies and footer policies. You can create header and footer policies by using the global ADOM. The global ADOM allows you to create header and footer policies once, and then assign the header and footer policies to multiple policy packages in one or more ADOMs.
For example, a header policy might block all network traffic to a specific country, and a footer policy might start antivirus software. Although you have unique policy packages in each ADOM, you might want to assign the same header and footer policies to all policy packages in all ADOMs.
Following is a visual summary of the process and a description of what occurs in the global ADOM layer, ADOM layer, and device manager layer.
Global ADOM layer
The global ADOM layer contains two key pieces: the global object database and all header and footer policies.
Header and footer policies are used to envelop policies within each individual ADOM. These are typically invisible to users and devices in the ADOM layer. An example of where this would be used is in a carrier environment, where the carrier would allow customer traffic to pass through their network but would not allow the customer to have access to the carrier’s network assets.
The ADOM layer is where FortiManager manages individual devices, VDOMs, or groups of devices. It is inside this layer where policy packages and folders are created, managed, and installed on managed devices. Multiple policy packages and folders can be created here. The ADOM layer contains one common object database per ADOM, which contains information such as addresses, services, antivirus and attack definitions, and web filtering and email filter.
Device manager layer
The device manager layer records information on devices that are centrally managed by the FortiManager unit, such as the name and type of device, the specific device model, its IP address, the current firmware installed on the unit, the device’s revision history, and its real-time status.
