All component updates originate from the Trend Micro ActiveUpdate server. When updates are available, the OfficeScan server and smart protection sources (Smart Protection Server or Smart Protection Network) download the updated components. There are no component download overlaps between the OfficeScan server and smart protection sources because each one downloads a specific set of components.
You can configure both the OfficeScan server and Smart Protection 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 smart protection sources.
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 on 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 protection source (Smart Protection Server or Smart Protection Network) 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 protection source.
See Smart Protection Sources for more information about smart protection sources.
The following table describes the update process for smart protection sources.
|
Smart Protection Source Update Process |
|
Update Process |
Description |
|
ActiveUpdate server | Smart Protection Network |
The Trend Micro Smart Protection Network receives updates from the Trend Micro ActiveUpdate server. Smart scan clients that are not connected to the corporate network send queries to the Trend Micro Smart Protection Network. |
|
ActiveUpdate server | Smart Protection Server |
A Smart Protection Server (integrated or standalone) receives updates from the Trend Micro ActiveUpdate server. Smart protection clients that are connected to the corporate network send queries to the Smart Protection Server. |
|
Smart Protection Network | Smart Protection Server |
A Smart Protection Server (integrated or standalone) receives updates from the Trend Micro Smart Protection Network. Smart protection clients that are connected to the corporate network send queries to the Smart Protection Server. |
