Policies and actions
You can create policies on Citrix Analytics to help you perform actions on user accounts when unusual or suspicious activities occur. Policies let you automate the process of applying actions such as disable a user, add users to a watchlist. When you enable policies, a corresponding action is applied immediately after an anomalous event occurs and the policy condition is met. You can also manually apply actions on user accounts with anomalous activities.
What are the policies?
A policy is a set of conditions that must be met to apply an action. A policy contains one or more conditions and a single action. You can create a policy with multiple conditions and one action that can be applied to a user’s account.
Risk score is a global condition. Global conditions can be applied to a specific user for a specific data source. You can keep a watch on user accounts that show any unusual activities. Other conditions are specific to data sources and their risk indicators. The conditions contain combinations of risk scores, default risk indicators, and custom risk indicators. You can add up to 4 conditions when creating a policy.
For example, if your organization uses sensitive data, you might want to restrict the amount of data shared or accessed by users internally. But if you have a large organization, it wouldn’t be feasible for a single administrator to manage and monitor many users. You can create a policy wherein, anyone who shares sensitive data excessively can be added to a watchlist or have their account disabled immediately.
Default policies are pre-defined and enabled on the Policies dashboard. They are created based on pre-defined conditions and a corresponding action is assigned to every default policy. You can either use a default policy or modify it based on your requirements.
Citrix Analytics supports the following default policies:
- Successful credentials exploit
- Potential data exfiltration
- Unusual access from a suspicious IP
- Unusual app access from an unusual location
- Low risk user - first time access from new IP
- First time access from device
For information about the preset conditions and actions regarding the preceding default policies, see Continuous risk assessment.
For information about the pre-defined policy for the geofencing use case, see Preconfigured policy.
How to add or remove conditions?
To add more conditions, select Add condition in the IF THE FOLLOWING CONDITION IS MET section of the Create Policy page. To remove a condition, select the - icon that is displayed next to the condition.
Default and custom risk indicators
The conditions menu is segregated based on Default Risk Indicators and Custom Risk Indicators tabs on the Create Policy page. Using these tabs, you can easily identify the type of risk indicator that you want to choose when selecting a condition for policy configuration.
What are the actions?
Actions are responses to suspicious events that prevent future anomalous events from occurring. You can apply actions on user accounts that display unusual or suspicious behavior. You can either configure policies to apply action on the user’s account automatically or apply a specific action manually from the user’s risk timeline.
You can view global actions or actions for each Citrix data source. You can also disable previously applied actions for a user at any time.
Irrespective of the data source that triggers a risk indicator, actions pertaining to other data sources can be applied.
The following table describes the actions that you can take.
|Action Name||Description||Data Sources Applicable On|
|Add to watchlist||When you want to monitor a user for future potential threats, you can add them to a watchlist.||All data sources|
|The Users in Watchlist pane displays all the users that you want to monitor for potential threats based on the unusual activity on their account. Based on your organization’s policy, you can add a user to the watchlist using the Add to watchlist action.|
|To add a user to the watchlist, navigate to the user’s profile, from the Actions menu, select Add to watchlist. Click Apply to enforce the action.|
|Notify administrator(s)||When a risk indicator is triggered for a user, you can manually notify to the administrators or create a policy for automatic notification. This action sends an email notification only to the Citrix Cloud administrators in your organization. You can also select the Citrix Cloud administrators to whom you want to notify. Note: By default, email notifications are disabled for your Citrix Cloud account. To receive email notifications, you need to enable it on your Cloud account. For more information, see Receive emailed notifications.|
|Request user response||When there is any unusual or suspicious activity on the user’s account, you can notify the user to confirm if the user identifies the activity. Based on the activity, you can determine the next course of action to be taken on the user’s account. You can apply this action only when you configure policies. You cannot apply this action manually. Note: To use this action, you must connect your Active Directory with Citrix Cloud and ensure that the user’s email is available in the Active Directory.||All data sources|
|Citrix Gateway actions|
|Log off user||When the action is applied, it logs off the user session that is currently active. It does not block any future user sessions.||Citrix Gateway on-premises and Citrix Application Delivery Management|
|Lock user||When a user’s account is locked due to anomalous behavior, they cannot access any resource through Citrix Gateway until the Gateway administrator unlocks the account.||Citrix Gateway on-premises|
|Unlock user||When a user’s account is accidentally locked although anomalous behavior was not detected, you can apply this action to unlock it and restore access to the account.||Citrix Gateway on-premises|
|Citrix Content Collaboration actions|
|Disable user||Citrix Analytics enables you to restrict or revoke their access by disabling their Content Collaboration account.||Citrix Content Collaboration|
|After their account is disabled, the user will see a notification. The notification on the logon page of their account asks them to reach their Content Collaboration administrator for further information.|
|Expire all links||When a user triggers the excessive file sharing indicator, Citrix Analytics enables you to expire all the links associated with that indicator.||Citrix Content Collaboration|
|When a user shares files excessively, the Excessive File Sharing risk indicator is triggered and the shared links are expired. When the shared links are expired, the link becomes invalid and it is not accessible by the users with whom the link was shared.|
|Change links to view-only sharing||When a user shares files excessively, you can apply this action. This action prevents other users from downloading, copying, or printing the files associated with the share links. For more information, see View-only sharing.|
|Remove folder access permission||When a user uploads an infected file, you can block the access permission of the user. The user’s access is restricted to the folder where the infected file was uploaded.|
|Remove upload permission to folder||When a user uploads an infected file, you can block the upload permission of the user. The user’s upload permission is restricted to the folder where the infected file was uploaded.|
|Citrix Virtual Apps and Desktops actions|
|Log off user||When the action is applied, it logs off the user session that is currently active. It does not block any future user sessions.||On-premises Virtual Apps and Desktops and Citrix Virtual Apps and Desktops service|
|Start session recording||If there is an unusual event on the user’s Virtual Desktops account, the administrator can begin recording the user’s activities of future logon sessions. If the user is on Virtual Apps and Desktops 7.18 or a greater version, the administrator can dynamically start and stop recording the user’s current logon session.||On-premises Virtual Apps and Desktops|
If you apply the Disable user action for a Content Collaboration user, the user’s account is not disabled until the Content Collaboration administrator sees the notification. During the interim period, the user can use their Content Collaboration account and the data continue to be processed by Citrix Analytics. After the Content Collaboration administrator disables the user’s account, the user must contact their Content Collaboration administrator to have their account reactivated. The Citrix Analytics administrator cannot enable disabled Content Collaboration accounts.
For on-premises Virtual Apps and Desktops, you must download an agent from Citrix Analytics and install it on the Delivery Controller to perform the Log Off User and the Start Session Recording actions. For more information on the agent, see Enable Analytics on Virtual Apps and Desktops Sites.
You can change a share link to the view-only sharing mode in the following ways:
On a user’s risk timeline, select the Excessive file sharing risk indicator. Click Actions > Change links to view-only sharing action. The action gets applied on the user account that triggered the risk indicator.
The Change links to view-only sharing action works only with the Excessive file sharing risk indicator. For any other risk indicators, if you apply this action, it does not take effect.
On the Share Links dashboard, click a share URL. You are redirected to the Share link risk timeline. Click Action > Change links to view-only sharing. The action gets applied on the particular share link.
The administrator must have an Enterprise account in Content Collaboration to use the Change links to view-only sharing action.
The View-Only Sharing is a feature available on a request in the Enterprise accounts of Citrix Content Collaboration. Before applying the Change links to view-only sharing action in Citrix Analytics, ensure that the View-Only Sharing feature is already enabled in the Content Collaboration Enterprise accounts of the user and the administrator. For more information, see the Citrix support article- CTX208601.
What happens when you apply this action?
This action prevents other users from downloading, copying, or printing the files associated with the share links.
The view-only sharing action applies only on the following file types:
Microsoft Office files
Image files (requires SZC v3.4.1 or later):
Audio and video files stored on a Citrix-managed Storage Zone.
Configure policies and actions
For example, following the steps below, you can create an Excessive file sharing policy. Using this policy, when a user in your organization shares an unusually large amount of data, the share links are automatically expired. You are notified when a user shares data that exceeds that user’s normal behavior. By applying the Excessive file sharing policy, and taking immediate action, you can prevent data exfiltration from any user’s account.
To create a policy, do the following:
After signing in to Citrix Analytics, go to Security > Policies > Create Policy.
From the IF THE FOLLOWING CONDITION IS MET list box, select the default or the custom risk indicator conditions upon which you want an action applied.
From the THEN DO THE FOLLOWING list, select an action.
In the Policy Name text box, provide a name and enable the policy using the toggle button provided.
Click Create Policy.
After creating a policy, the policy appears on the Policies dashboard.
The Policies dashboard displays the policies associated with the data sources that are successfully discovered and connected to Citrix Analytics. The dashboard does not display the policies that have conditions defined for the undiscovered data sources.
For example, you have selected a risk indicator from Content Collaboration as a condition for your policy. But you do not have a subscription to use Citrix Content Collaboration and therefore Citrix Analytics does not discover this data source. So, your policy does not appear on the Policies dashboard.
However, turning off data processing for an already connected data source does not affect the existing policies on the Policies dashboard.
Request user response
Request End User Response is a global action using which you can alert a user immediately after you detect an unusual activity. When you apply the action, an email notification is sent to the users for any usual activities detected in their Citrix accounts. The users need to response through the email about the legitimacy of their activity.
Prerequisite: To use this action, you must connect your Active Directory with Citrix Cloud and ensure that the user’s email is available in the Active Directory. For information on how to connect your Active Directory, see Connect Active Directory to Citrix Cloud.
Based on the user’s response, you can determine the next course of action that you want to take. If you receive a response that the user performed the reported activity, then the activity is not suspicious and you need not take action on the user’s account. The daily limit to send security alerts to the user is three emails.
Consider a Citrix Content Collaboration user whose risk score has exceeded 80 in a duration of 80 minutes. You can alert the user about this unusual behavior by applying the Request End User Response action. A security alert is sent to the user from the email ID
The email contains the following information:
User’s activity that triggered the risk indicator
Date and time of the user activity
Locations (cities and countries) from where products or services are successfully accessed. If the city or country is unavailable, the corresponding value is shown as “Unknown”
The Request End User Response action is added to the user’s risk timeline.
The Request End User Response action is supported only when your organization is onboarded to the United States region. If your organization is onboarded to the European Union region in Citrix Cloud, you cannot use this action.
How to set the user response time?
You can configure the user’s response time to your security alert email. If the user does not respond about the reported activity within the specified time period, the user is added to the watchlist for monitoring.
Follow the steps to configure the user’s response time:
Click Settings > Alert Settings > End User Email Settings.
On the End User Email Settings page, enter the number of minutes on the text box.
Click Save Changes.
You can also add a banner, header text, and footer text in the security alert email to make it look legitimate, attract users’ attention, and increase the response time. For more information, see End user email settings.
Notify user after applying disruptive action
In this action type, you can apply a disruptive action such as Log off user and Lock user on the user’s account when an unusual activity is detected. When an action is applied on the user’s account, services to their account might be interrupted. In such instances, the user must contact the administrator to be able to access their account like before.
Consider a Citrix Content Collaboration user whose risk score has exceeded 80 in a duration of 80 minutes. You can log the user off. Once this task is performed, the user cannot access their account and an email notification is sent to the user from the email ID
email@example.com. The email contains details of the event such as the activity, device, date and time, and the IP address. The user must contact the administrator to access their account as before.
Apply an action manually
Consider a user, Lemuel who signs in to a network by using a new device for the first time. To monitor her account since her behavior is unusual, you can use the Notify administrator(s) action.
To manually apply the action to the user, you must:
Navigate to a user’s profile and select the appropriate risk indicator. From the Actions menu, select the Notify administrator(s) action and click Apply.
By default, an email notification is sent to all Citrix Cloud administrators to monitor her account. You can also select the Citrix Cloud administrators to whom you want to notify. The action applied is added to her risk timeline, and the action details are displayed on the right pane of the risk timeline page.
By default, email notifications are disabled for your Citrix Cloud account. To receive email notifications, you need to enable it on your Cloud account. For more information, see Receive emailed notifications.
You can view the Policies dashboard to manage all the policies created on Citrix Analytics to monitor and identify inconsistencies on your network. On the Policies dashboard, you can:
View the list of policies
Details of the policy
Name of the policy
Status – Enabled or disabled.
Duration of the policy – Number of days the policy has been active or inactive.

On the Modify Policy page, click the Enabled slider button on the bottom of the page.
Citrix Analytics supports the following modes on policies:
Enforcement mode - In this mode, the configured policies impact user accounts.
Monitor mode - In this mode, the configured policies do not impact user accounts. You can set policies to this mode if you want to test any policy configurations.
Use the following instructions to configure modes on policies:
Navigate to Security > Policies.
On the Policies page, select the icon at the top right corner, that is displayed next to the Search bar. The SELECT MODE window is displayed.
Select the mode of your choice and click Save Settings.
The default policies created by Analytics are set to monitor mode. As a result, the existing policies also inherit this mode. You can assess the impact of all the policies together and then, change them to enforcement mode.
Self-service search for Policies
On the self-service search page, you can view the user events that have satisfied the conditions defined in the policies. The page also displays the actions applied on these user events. Filter the user events based on the applied actions.
