If there are additional files or processes that you want the Host Sensor to ignore you can configure custom exclusions to identify paths for files and processes that you do not want Host Sensors to monitor. TDR makes this easier with predefined exclusion lists for interoperability with popular third-party AV software. To resolve this issue, you must add exclusions in the AV software and in TDR. In some cases, the TDR Host Sensor might have conflicts with the antivirus (AV) software installed on your endpoints. This section contains links to additional resources from third parties that should be reviewed before configuring antivirus software on Citrix XenApp servers.You can enable TDR exclusions for software or files that you want the TDR Host Sensor to ignore. Required Antivirus Software Configuration for the EdgeSight Server: CTX114906 – Required Antivirus Software Configuration for the EdgeSight Server.

Required Antivirus Software Configuration for the EdgeSight Agent: CTX111062 – Required Antivirus Software Configuration for the EdgeSight Agent. Provisioning Services Antivirus Best Practices: CTX124185 – Provisioning Services Antivirus Best Practices. In addition to the XenApp-specific antivirus configurations detailed in the previous section, Citrix recommends applying the settings outlined in the following articles, if applicable. Recommended Settings for Other Citrix Technologies If using the streamed user profile feature of Citrix Profile management, ensure the antivirus solution is configured to be aware of Hierarchical Storage Manager (HSM) drivers. The following list contains general antivirus recommendations that should be reviewed prior to implementing any type of exclusions or optimizations: Citrix also recommends organizations to engage their antivirus and security teams to review the following guidelines before proceeding with any type of production deployment. Citrix does not recommend implementing any of these exclusions or optimizations until rigorous testing has been conducted in a lab environment to thoroughly understand the tradeoffs between security and performance. However, the following guidelines typically represent the best tradeoff between security and performance. It is important to understand that antivirus exclusions and optimizations increase the attack surface of a system and might expose computers to a variety of real security threats. Warning! This article contains antivirus exclusions. These antivirus guidelines are not vendor-specific and are independent of the version of XenApp deployed, except where explicitly stated.

This article provides guidelines for configuring antivirus software in Citrix XenApp environments and resources for configuring antivirus software on other Citrix technologies and features (EdgeSight, Provisioning Services, and so on).
