42 Chapter 2 • Designing a Managed Antivirus Infrastructure Introduction In a managed Norton AntiVirus Corporate Edition (NAVCE) environment, server groups will provide a physical and logical structure in which to manage your network clients. Server groups create a manageable collection of servers and workstations running the NAVCE software that you, the administrator, can configure quite easily and efficiently, as changes made once will propagate to all members of the server group without any additional effort. You can also perform NAVCE-related tasks like scheduling regular hard disk scans and performing ad-hoc virus sweeps of an entire server group with only one or two. | 42 Chapter 2 Designing a Managed Antivirus Infrastructure Introduction In a managed Norton AntiVirus Corporate Edition NAVCE environment server groups will provide a physical and logical structure in which to manage your network clients. Server groups create a manageable collection of servers and workstations running the NAVCE software that you the administrator can configure quite easily and efficiently as changes made once will propagate to all members of the server group without any additional effort. You can also perform NAVCE-related tasks like scheduling regular hard disk scans and performing ad-hoc virus sweeps of an entire server group with only one or two mouse clicks thus freeing you to attend to other matters. NAVCE servers within a server group can serve several different functions in managing your NAVCE clients. Each server group contains a primary server that acts as the staging point for all configuration changes and updates that you make to the server group any changes will be copied to the primary server first and then circulated to the rest of the server group.Any additional servers within the group are considered secondary servers.They provide load balancing by acting as parent servers to NAVCE clients receiving updates from the primary server and copying them to the NAVCE clients under their jurisdiction.A final server type that can be quite useful on a large enterprise network is the master primary server which acts as a single point of contact with the Symantec Web site to download all product and definition updates.To better understand this take a look at Figure 2.1. In this diagram you can see that the master primary server receives updates from the Symantec Web site www.symantec.com and copies them out to the primary servers of the three different server groups shown. Each server group then has several secondary servers functioning in addition to the primary server which then copies the updates to the NAVCE clients within each group. .
