Figure 1: VCMServer Installation
IIS, the web application, SQL Server, and the Collector service are installed on a server machine referred to as the
“Collector host”. Several different types of personnel utilize the five components of VCM. Domain administrators
create the accounts and manage the infrastructure in which VCM runs. The infrastructure includes domain controllers,
routers, certificate servers, SMTP email, domain name service (DNS) and DHCP. A VCM installer loads the VCM
software and configures IIS, SQL server, the Collector, and other services. The installer is also the first VCM
administrator and is responsible for authorizing the other administrators and regular VCM users from the inventory of
accounts managed by the domain administrators. VCM users and administrators log on to VCM and use its web
interface to administer managed machines via the Agents, run Compliance tests, and generate reports. Agents can be
installed, upgraded, and un-installed by either VCM administrators, users or managed machine administrators.
Conceptually, the VCM services, hosts, and personnel can be organized into the following trust zones:
