All component updates originate from the Trend Micro ActiveUpdate server. When updates are available, the OfficeScan server and Smart Scan Server (local or global) download the updated components. There are no component download overlaps between the two servers because each one downloads a specific set of components.
You can configure both the OfficeScan server and Smart Scan Server to update from a source other than the Trend Micro ActiveUpdate server. To do this, you need to set up a custom update source. If you need assistance setting up this update source, contact your support provider.
The OfficeScan server downloads most of the components that clients need. The only component it does not download is the Smart Scan Pattern, which is downloaded by a Smart Scan Server.
If an OfficeScan server manages a large number of clients, updating may utilize a significant amount of server computer resources, affecting the server’s stability and performance. To address this issue, OfficeScan has an Update Agent feature that allows certain clients to share the task of distributing updates to other clients.
The following table describes the different component update options for the OfficeScan server and clients, and recommendations when to use them:
|
Server-client update options |
|
Update Option |
Description |
Recommendation |
|
ActiveUpdate server | OfficeScan server | Clients |
The OfficeScan server receives updated components from the Trend Micro ActiveUpdate server (or other update source) and initiates component update on clients. |
Use this method if there are no low-bandwidth sections between the OfficeScan server and clients. |
|
ActiveUpdate server | OfficeScan server | Update Agents | Clients |
The OfficeScan server receives updated components from the ActiveUpdate server (or other update source) and initiates component update on clients. Clients acting as Update Agents then notify clients to update components. |
If there are low-bandwidth sections between the OfficeScan server and clients, use this method to balance the traffic load on the network. |
|
ActiveUpdate server | Update Agents | Clients |
Update Agents receive updated components directly from the ActiveUpdate server (or other update source) and notifies clients to update components. |
Use this method only if you experience problems updating Update Agents from the OfficeScan server or from other Update Agents. Under most circumstances, Update Agents receive updates faster from the OfficeScan server or from other Update Agents than from an external update source. |
|
ActiveUpdate server | Clients |
OfficeScan clients receive updated components directly from the ActiveUpdate server (or other update source). |
Use this method only if you experience problems updating clients from the OfficeScan server or from Update Agents. Under most circumstances, clients receive updates faster from the OfficeScan server or from Update Agents than from an external update source. |
A Smart Scan Server downloads the Smart Scan Pattern. Smart scan clients do not download this pattern. Clients verify potential threats against the pattern by sending scan queries to the Smart Scan Server.
See Smart Scan Server for more information about Smart Scan Servers and Smart Scan Server Update for server update details.
The following table describes the update process for Smart Scan Servers.
|
Smart Scan Server update process |
|
Update Process |
Description |
|
ActiveUpdate server | Global Smart Scan Server |
The Global Smart Scan Server receives updates from the Trend Micro ActiveUpdate server. Smart scan clients that are not connected to the corporate network send scan queries to the Global Smart Scan Server. |
|
ActiveUpdate server | Local Smart Scan Server |
A local Smart Scan Server (integrated or standalone) receives updates from the Trend Micro ActiveUpdate server. Smart scan clients that are connected to the corporate network send scan queries to the local Smart Scan Server. |
