Updating a Control Manager network is a two-step process:
Obtain the latest update components from Trend Micro. Control Manager can download components either directly from the Trend Micro update server, or from an alternative location.
Deploy these components to the managed products.
Control Manager deploys update components to managed products, including:
Pattern rules/Cleanup templates*
Engines (scan engines, damage cleanup engines*)
Anti-spam rules
Product programs (depending on the product)
* - Control Manager can only update damage cleanup templates/engines after activating Damage Cleanup Services
Trend Micro strongly recommends regularly updating these components to help ensure managed products can protect your network against the latest threats. For product program updates, refer to the specific program�s documentation.
Deploying updates to managed products is a bandwidth intensive operation. If possible, it is important to perform deployments when it will have the least impact on the network.
You can stagger the deployment of component updates using Deployment Plans.
Furthermore, check that the network connection between your Control Manager server and managed products can accommodate the updates. This will be a factor to consider when deciding how many Control Manager servers your network needs.
The actual bandwidth usage will vary with the actual managed products. The following sections list differences among different Trend Micro products:
