Network zones are address-based network zone information as reported by or assigned to connectors and integrated as an asset property. You can access zone through the Zones Tab of the Assets resource trees, and the Zone Editor.
The system can gather and integrate zone information by any of the methods. Only one method can apply with a given connector.
If an AUP file (ArcSight SmartConnector Content update) is installed with a connector, the zone information, if present, provides addressed-based recognition.
If a defaultzones.csv file is installed in the connector's ARCSIGHT_HOME/system/agent/acp directory, it overrides an AUP file if present.
If the various zone URI values are set in the Connector Editor, in the Network section of the Networks: Content tab, they override URIs from an AUP file, a defaultzones.csv file, or the defaults.
