Let's dig into Agent Updates with VIPRE Endpoint Security Server, what they are, and how the agent receives them.

Types of Agent Updates

There are two different types of updates:

• Threat definition updates identify and remediate malware in your environment and are updated several times each day, as often as hourly. The full threat definitions are approximately 70 MB and reside on each machine that contains a VIPRE Agent. The average update chunk size is approximately 67 KB.
• Software updates pertain to the Agent software and occur a few times a year. Software Updates are approximately 15 MB. These software updates can include patches, version releases, or Beta releases (Beta releases are only made available by request) for VIPRE Antivirus Business, VIPRE Business Premium, and VIPRE Endpoint Security, as well as different languages besides English.

Distributing Agent Updates

When an agent is first installed, it immediately gets threat definitions updates. The Agents receive ongoing updates based on the policy they are assigned. Both definitions and software updates are sent from VIPRE Site Service (VSS) on ports 18082. If you enabled “Download via the Internet if local updates are unavailable,” Agents will obtain their definition updates from VIPRE Security’s update server (Port 80) if they are unable to contact the update server specified in the policy.

Updates are NOT delivered from the VIPRE Admin Console or by a request over the Internet from the Agent.

In order for VSS to get the updates for distribution, it is required that both Simple Object Access Protocol (SOAP) headers and Internet access be allowed from the machine hosting VSS to the external Internet.

Specifically, set SOAP via port 80 outbound and inbound for the following:

• updates.sunbeltsoftware.com - checks for software updates and allows software and definition updates to be distributed.
• ne.edgecastcdn.net - allows software updates and definition updates to be distributed.

Steps to configure updates for your environment:

1. Select agent software for the site
2. Manage site updates
3. Manage agent updates for policies
4. If necessary, create a remote update server
