Security Agent Update Process

After you have set up and saved the customized update source list, the update process proceeds as follows:

1. The Security Agent updates from the first source on the list.

2. If unable to update from the first source, the Security Agent updates from the second source, and so on.

3. If unable to update from all sources, the Security Agent checks the following settings on the Update Source screen:

   Table 1. Additional Settings for Custom Update Sources

   Setting	Description
   Update Agents update components, domain settings, and agent programs and hot fixes, only from the Apex One server	If this setting is enabled, Update Agents update directly from the Apex One server and disregard the Customized Update Source List. If disabled, Update Agents apply the customized update source settings configured for normal agents.
   Security Agents update the following items from the Apex One server if all customized sources are unavailable or not found:
   Components	If this setting is enabled, the agent updates components from the Apex One server. If disabled, the agent then tries connecting directly to the Trend Micro ActiveUpdate server if any of the following is true: In Agents > Agent Management, click Settings > Privileges and Other Settings > Other Settings (tab) > Update Settings, the option Security Agents download updates from the Trend Micro ActiveUpdate Server is enabled. The ActiveUpdate server is not included in the Customized Update Source List. Note: Only components can be updated from the ActiveUpdate server. Domain settings, programs and hot fixes can only be downloaded from the Apex One server or Update Agents. You can speed up the update process by configuring agents to only download pattern files from the ActiveUpdate server. For more information, see ActiveUpdate Server as the Security Agent Update Source.
   Domain settings	If this setting is enabled, the agent updates domain-level settings from the Apex One server.
   Security Agent programs and hot fixes	If this setting enabled, the agent updates programs and hot fixes from the Apex One server.

4. If unable to update from all possible sources, the agent quits the update process.
