Citrix Gateway

Configuring Antivirus, Firewall, Internet Security, or Antispam Expressions

October 5, 2020

Contributed by:

You configure settings for antivirus, firewall, Internet security, and antispam policies within the Add Expression dialog box. The settings for each policy are the same: the differences are the values that you select. For example, if you want to check the user device for Norton AntiVirus Version 10 and ZoneAlarm Pro, you create two expressions within the session or preauthentication policy that specify the name and version number of each application.

When you select Client Security as the expression type, you can configure the following:

Component: The type of client security, such as antivirus, firewall, or registry entry.
Name: The name of the application, process, file, registry entry, or operating system.
Qualifier: The version or the value of the component for which the expression checks.
Operator: Checks if the value exists or is equal to the value.
Value: The application version for antivirus, firewall, Internet security, or antispam software on the user device.
Frequency: Frequency with which a post-authentication scan is run, in minutes.
Error weight: A weight assigned to each error message contained in a nested expression when multiple expressions have different error strings. The weight determines which error message appears.
Freshness: Defines how old a virus definition can be. For example, you can configure the expression so virus definitions are no older than three days.
