Active Agent
The Active Agent serves as the contact window between the WFBS-SVC server and all WFBS-SVC Agents in a company.
It is responsible for:
  • Communicating with the WFBS-SVC server
  • Distributing updates and pattern files to other clients
The Active Agent periodically checks the Trend Micro ActiveUpdate (TMAU) Server for component and pattern file updates. If there are updates, the Active Agent downloads the update and notifies Inactive Agents about the update.
Inactive Agents are then given a random time between 0 seconds to 15 minutes to download the update from the Active Agent. This prevents excessive utilization of the Active Agent's system resources.
Using the Active Agent election algorithm, WFBS-SVC Agents in a company elect one Agent to be the Active Agent. If the device hosting the current Active Agent becomes unavailable, all other Agents immediately elect a new Active Agent.
Inactive Agents
All the WFBS-SVC Agents, other than the Active Agent, are known as Inactive Agents. Inactive Agents are updated by the Active Agent.
Updates in WFBS-SVC
WFBS-SVC enables upgrading to the latest components hassle-free by having the Active Agent automatically receive updated components from the Trend Micro Active Update Server. All Inactive Agents then receive updates from the Active Agent. By default, Agents are updated every two hours.
Currently, only Windows Agents use the Active Agent update method. All other Agents receive their updates from Trend Micro Active Update servers.
Agents not connected to the LAN will receive updates from Trend Micro Active Update instead of from the Active Agent.
Trend Micro recommended settings for component updates provide reasonable protection to small and medium-sized business. If necessary, you can run manual updates any time for all devices in a group by clicking Devices > {group} > Other > Update Now.
Incremental Update Support
ActiveUpdate supports incremental updates of pattern files. Rather than downloading the entire pattern file each time, ActiveUpdate can download only the portion of the file that is new, and append it to the existing pattern file. This efficient update method can substantially reduce bandwidth needed to update your antivirus software.
Default Update Times
The default update times for the following agents are:
  • Windows Agent: Every hour
  • Mac Agent: Every hour
  • Android Agent: Every 24 hours
Additionally, as soon as you install the Agent, all components are immediately updated.
The Trend Micro recommended settings for component updates provide reasonable protection to small- and medium-sized business. If necessary, you can run Manual updates.
Note: Generally, Trend Micro updates the scan engine or program only during the release of a new version. However, Trend Micro releases pattern files frequently.
Manual Updates
The Active Agent periodically checks commands from the WFBS-SVC. If they include Update Now, the Active Agent downloads the update from Trend Micro Active Update, and then notifies Inactive Agents to update.
