Status Indicator (

)

Identifies whether there is enough endpoint data to analyze an alert.

Check box to select one or more alerts on which to perform actions. Select multiple alerts to assign all selected alerts to an analyst, or to change the status or severity of all selected alerts.

ACTION

Action taken by the alert sensor, either Detected or Prevented with action status displayed in parenthesis. Options are:

AGENT OS SUB TYPE

The operating system subtype of the agent from which the alert was triggered.

ALERT ID

A unique identifier that Cortex XDR assigns to each alert.

ALERT NAME

Module that triggered the alert. If the alert was generated by Cortex XDR , the Alert Name will be the specific Cortex XDR rule that created the alert (BIOC, IOC, or Correlation Rule name). If from an external system, it will carry the name assigned to it by Cortex XDR . Alerts that match an alert starring policy also display a purple star.

Alerts that contain a Featured Alert Field are displayed with flag.

Alerts associated with Identity Analytics are displayed with an Identity Analytics tag.

ALERT SOURCE

Source of the alert: BIOC, Analytics BIOC, Correlation, IOC, XDR Agent, Firewall, or Analytics.

ALERT TRIGGERED AN AUTOMATION RULE

indicates that the alert triggered an automation rule.

APP-ID

Related App-ID for an alert. App-ID is a traffic classification system that determines what an application is irrespective of port, protocol, encryption (SSH or SSL) or any other evasive tactic used by the application. When known, you can also pivot to the Palo Alto Networks Applipedia entry that describes the detected application.

APP CATEGORY

APP-ID category name associated with a firewall alert.

APP SUBCATEGORY

APP-ID subcategory name associated with a firewall alert.

APP TECHNOLOGY

APP-ID technology name associated with a firewall alert.

CATEGORY

Alert category based on the alert source. An example of an XDR Agent alert category is Exploit Modules. An example of a BIOC alert category is Evasion. If a URL filtering category is known, this field also displays the name of the URL filtering category.

CGO SIGNATURE

Signing status of the CGO:

CGO SIGNER

The name of the software publishing vendor that signed the file in the causality chain that led up to the alert.

CLOUD IDENTITY TYPE

Classification is used to map the identity type that initiated an operation that triggered an alert. For example, Service, Application, and Temporary Credentials.

CLOUD IDENTITY SUB-TYPE

A more specific classification of the identity initiated the operation. For example, for Identity Type: Temporary Credentials the subtype could be Assumed Role.

CLOUD OPERATION TYPE

Represents what has happened because of the identity operation. For example, Create, Delete, and Modify.

CLOUD PROJECT

Represents the cloud provider folders or projects. For example, AWS Accounts and Azure Subscriptions.

CLOUD PROVIDER

The name of the cloud provider where the alert occurred:

CLOUD REFERENCED RESOURCE

Represents the resources that are referenced in the alert log. In most cases, the referred resource will be where the operation was initiated on.

CLOUD RESOURCE TYPE

Classifications are used to map similar types of resources across different cloud providers. For example, EC2, Google Compute Engine, and Microsoft Compute are all mapped to Compute.

CLOUD RESOURCE SUB-TYPE

A more specific classification is used to map the types of resources. For example, DISK, VPC, and Subnet are all mapped to Compute.
