    • Other violation details such as violence occurrence time and detection message

Behavior checks with no violations

Apart from violation details, you can visualize a 3-week traffic prediction based on the machine learning algorithm. As an administrator, this 3-week prediction enables you to:

  • Analyze the traffic pattern even if no violations are observed

  • Take troubleshooting actions for any unusual traffic patterns observed from the predictions

  • Observe that Citrix ADM is processing data, apart from the anomalies

In the Security Violations page, click the Behavior checks with no violation tab to view the 3-week traffic prediction.

No violation

The security violations are displayed. Consider that you want to view the traffic prediction for Excessive Unique IPs Per Geo.

Prediction example

From the example image, you can view:

  • Expected Unique IP Range – Citrix ADM has predicted the expected IP range based on the traffic pattern

  • Unique IP – Citrix ADM has predicted about 1970 unique IPs that will be transacting with the app from Malaysia

Using this data, you can proactively take precautionary steps to avoid these excessive unique IPs.

If Citrix ADM does not have any predictions for a security violation, you can view the following message:
