See the causality of a cloud-type alert—the entire process execution chain that led up to the alert in the Cortex XSIAM app.

The Cloud Causality View provides a powerful way to analyze and respond to Cortex XSIAM alerts and Cloud Audit Logs. The scope of the Cloud Causality View is the Causality Instance (CI) of an event to which this alert pertains. The Cloud Causality View presents the event identity and /or IP address and the actions performed by the identity on the cloud resource. On each node in the CI chain, Cortex XSIAM provides information to help you understand what happened around the event.

The Causality View comprises the following sections:


Summarizes information about the alert you are analyzing, including the type of Cloud Provider, Project, and Region on which the event occurred. Select View Raw Log to view the raw log as provided by the Cloud Provider in JSON format.

Causality Instance Chain

Includes the graphical representation of the Causality Instance (CI) along with other information and capabilities to enable you to conduct your analysis.

The Causality View presents a single event CI chain. The CI chain is built from Identity and Resource nodes. The Identity node represents for example keys, service accounts, and users, while the Resource node represents for example network interfaces, storage buckets, or disks. When available, the chain might also include an IP address and alerts that were triggered on the Identity and Cloud Resource.

Causality data is displayed as follows:

The Causality View provides an interactive way to view the CI chain for an alert. You can move it, extend it, and modify it. To adjust the appearance of the CI chain, you can enlarge/shrink the chain for easy viewing using the size controls on the right. You can also move the chain around by selecting and dragging it. To return the chain to its original position and size, click causality-view-reset-icon.png in the lower-right of the CI graph.

Identity Node

Displays the name of the identity, generated alert information, and if available the associated IP address.

To further investigate the user:

  1. Hover over an Identity node to display, if available, the identity Analytics Profiles.

  2. Select the Identity node to display in the Entity Data section additional information about the Identity entity.

  3. Select the Alert icon to display in the Entity Data section additional information about the alert.

IP Address Node

Displays the IP address associated with the Identity.


Lists the type of operations performed by the identity on the cloud resources. Hover over the operation to display the original operation name as provided by the Cloud Provider.

Cloud Resource Node

Displays the referenced resource on which the operation was performed. Cortex XSIAM displays information on the following resources:


Type of Resource


Compute Instance Resource


Disk Resource


General Resource


Image Resource


Network Interface Resource


Security Group (FW Rule) Resource


Storage Bucket Resource


Virtual Private Cloud (VPC) Resource

To further investigate the resource:

  1. Hover over a Resource node to display, if available, the resource Analytics Profiles and Resource Editors statistics.

  2. Select the Resource node to display in the Entity Data section additional information about the Resource entity.

Entity Data

Provides additional information about the entity that you selected. The data varies by the type of entity but typically identifies information about the entity related to the cause of the alert and the circumstances under which the alert occurred.

Events Table

Displays up to 100,000 related events and up to 1,000 related alerts.

To continue the investigation, in the Alerts table, you can perform the following actions from the right-click pivot menu:

  • Investigate Causality Chain of the associated alert.

  • Open in XQL to populate the event in an XQL search query that you can further refine if needed.

  • Manage Alert to perform available actions.

  • Pivot to views to view the related incidents.

In the All Events table, Cortex XSIAM displays detailed information about each of the related events. To simplify your investigation, Cortex XSIAM scans your Cortex XSIAM data aggregating the events that have the same Identity or Resource and displays the entry with an cloud-causality-aggregated-events.png aggregated icon. Right-click and select Show Grouped Events to view the aggregated entries.

Entries highlighted in red indicate that the specific event triggered an alert. To continue the investigation, right-click to View in XQL.
