Hosts

Most resources that are referenced in an IT or cloud infrastructure are conceptually “hosted on” or “hosted by” other resources. For example, “applications” are hosted on “web servers” or “users” may be hosted on a “network connected device” or a “terminal”. In addition, networked resources are “hosted” by some device attached to some network.

The host resource often provides context or location information for the resource it is hosting at the time the Actual Event was observed and recorded (e.g., an IP address, software agent, platform, etc.). Providing a means to record host information with a CADF Event Record is valuable for audit purposes because compliance policies and rules are often based on such information.
