Manage Alerts

You can manage Cortex XDR alerts and view alert details from the Alerts page.

Copy Alerts

You can copy an alert into memory as follows:
  • Copy the URL of the alert record
  • Copy the value for an alert field
  • Copy the entire row of alert record
With either option, you can paste the contents of memory into an email to send. This is helpful if you need to share or discuss a specific alert with someone. If you copy a field value, you can also easily paste it into a search or begin a query.
  • Create a URL for an alert record:
    1. From the
      Alerts
      page, right-click the alert you want to send.
    2. Select
      Copy alert URL
      .
      Cortex XDR saves the URL to memory.
    3. Paste the URL into an email or use as needed to share the alert.
  • Copy a field value in an alert record:
    1. From the
      Alerts
      page, right-click the field in the alert that you want to copy.
    2. Select
      Copy text to clipboard
      .
      Cortex XDR saves the field contents to memory.
    3. Paste the value into an email or use as needed to share information from the alert.
  • Copy the entire row of alert record
    1. From the
      Alerts
      page, right-click on one or more alerts you want to copy.
    2. Select
      Copy entire row(s)
      .
    3. Paste the value into an email or use as needed to share information from the alert.

Analyze an Alert

To help you understand the full context of an alert, Cortex XDR provides a powerful analysis view that empowers you to make a thorough analysis very quickly.
The Causality View is available for XDR agent alerts that are based on endpoint data and for alerts raised on network traffic logs that have been stitched with endpoint data.
To view the analysis:
  1. From the
    Alerts
    page, locate the alert you want to analyze.
  2. Right-click anywhere in the alert, and select
    Investigate Causality Chain
    .
  3. Choose whether to open the Causality View card for an alert in a new tab or the same tab.
    You can also view the causality chain over time using the Timeline view.
  4. Review the chain of execution and available data for the process and, if available, navigate through the processes tree.

Create Profile Exceptions

For XDR Agent alerts, you can create profile exceptions for Window processes, BTP, and JAVA deserialization alerts directly from the
Alerts
table.
  1. Right-click an
    XDR Agent
    alert which has a category of
    Exploit
    and
    Create alert exception
    .
  2. Select an
    Exception Scope
    :
    • Global
      —Apply the exception across your organization.
    • Profile
      —Apply the exception to an existing profile or click and enter a
      Profile Name
      to create a new profile.
  3. Add
    the scope.
  4. (
    Optional
    ) View your profile exceptions.
    1. Navigate to
      Endpoints
      Policy Management
      Profiles
      .
    2. In the
      Profiles
      table, locate the OS in which you created your global or profile exception and right-click to view or edit the exception properties.

Create a Featured Alert Field

To better highlight alerts that are significant to you, Cortex XDR enables you to label specific alert attributes as Featured Alert Fields. Featured alert fields help you track in the Alerts Table alerts that involve a specific host names, user names, and IP addresses.
  1. Navigate to
    Investigation
    Incident Management
    Featured Fields
    and select a type of featured field:
    • Hosts
    • Users
    • IP Addresses
    • Active Directory
  2. In the field type table,
    Add featured
    Field Name
    to define a list of alert fields you want flagged in the Alerts Table. You can either
    Create New
    featured alert field from scratch or
    Upload from File
    .
    • To create a new alert field:
    1. Enter one or more field values and
      Add
      to the list.
    2. (
      Optional
      ) Add a comment.
    3. Add the featured alert field.
    • To import fields:
    1. Browse
      or
      Drag and Drop
      your
      CSV
      file of field values.
      Download example file
      to ensure you using the correct format.
    2. Import
      your file.
  3. (
    Optional
    ) Manage your featured alert field list.
    • Locate the alert field you want to edit or delete.
    • Right-click and
      Edit
      Field Name
      to modify the field definition, or
      Delete
      Field Name
      to remove the featured flag.
  4. Investigate alerts that contain the featured alert fields.
    • Navigate to the Alerts Table.
    • In the Alerts table, sort according to the following fields:
      • Contains Featured Host
      • Contains Featured User
      • Contains Featured IP Address
    • In the
      Alert Name
      field, Cortex XDR displays alerts that contain a matching featured field value with a featured-alert-field-flag.png flag.
      Featured Active Directory values are displayed in the User and Host fields accordingly.
    • (
      Optional
      ) Create an incident scoring rule using the Alert table
      Contains Featured
      Field Name
      fields to further highlight and prioritize alerts containing the Host, User, and IP address attributes.

View Generating BIOC or IOC Rule

Easily view the BIOC or IOC rules that generated alerts directly from the Alerts table.
  1. From the
    Alerts
    page, locate alerts with
    Alert Sources
    :
    XDR BIOC
    and
    XDR IOC
    .
  2. Right-click the row, and select
    View generating rule
    .
    Cortex XDR opens the BIOC rule that generated the alert in the
    BIOC Rules
    page. If the rule has been deleted, an empty table is displayed.
  3. Review the rule, if necessary, right-click to perform available actions.

Retrieve Additional Alert Details

To easily access additional information relating to an alert:
  1. From the
    Alerts
    page, locate the alert for which you want to retrieve information.
  2. Right-click anywhere in the alert, and select one of the following options:
    • Retrieve alert data
      —Cortex XDR can provide additional analysis of the memory contents when an exploit protection module raises an XDR Alert. To perform the analysis you must first retrieve alert data consisting of the memory contents at the time the alert was raised. This can be done manually for a specific alert, or you can enable Cortex XDR to automatically retrieve alert data for every relevant XDR Alert. After Cortex XDR receives the data and performs the analysis, it issues a verdict for the alert. You can monitor the retrieval and analysis progress from the
      Action Center
      (pivot to view
      Additional data
      ). When analysis is complete, Cortex XDR displays the verdict in the
      Advanced Analysis
      field.
    • Retrieve related files
      —To further examine files that are involved in an alert, you can request the Cortex XDR agent send them to the Cortex XDR management console. If multiple files are involved, Cortex XDR supports up to 20 files and 200MB in total size. The agent collects all requested files into one archive and includes a log in JSON format containing additional status information. When the files are successfully uploaded, you can download them from the Action Center for up to one week.
    • View full endpoint details
      —Jump to a filtered view of the Endpoint Administration page by endpoint ID. This unique ID is assigned by the Cortex XDR agent to identify the endpoint.
    • For
      PAN NGFW
      source type alerts,
      Download triggering packet
      —Download the session PCAP containing the first 100 bytes of the triggering packet directly from Cortex XDR. To access the PCAP, you can download the file from the Alerts table, Incident, or Causality view.
  3. Navigate to
    Response
    Action Center
    to view retrieval status.

Export Alert Details to a File

To archive, continue investigation offline, or parse alert details, you can export alerts to a tab-separated values (TSV) file.
  1. From the
    Alerts
    page, adjust the filters to identify the alerts you want to export.
  2. When you are satisfied with the results, click the download icon ( download-to-file-icon.png ).
    The icon is grayed out when there are no results.
    Cortex XDR exports the filtered result set to the TSV file.
