    The shortcut value must be a keyboard letter, A through Z, and cannot be the same for both shortcuts.

Select Timezone
Abstract

Learn more about configuring a specific timezone.

Select your own specific timezone. Selecting a timezone affects the timestamps displayed in the Cortex XDR management console, auditing logs, and when exporting files.

  • In the Timezone section, select the timezone in which you want to display your Cortex XDR data.

Define Timestamp Format
Abstract

    Note

    The setting is configured per user and not per tenant.

Define Scoped Server Access
Abstract

Learn more about defining scoped server access.

Select Disabled or Enabled. When Enabled, access restrictions are enforced only to users with an assigned scope. A user can inherit scope permissions from a group or have a scope assigned directly on top of the role assigned from the group.

If enabled, you must select the SBAC Mode, type, which is defined per tenant.

  • Permissive—Enables users with at least one scope tag to access the relevant entity with that same tag.

  • Restrictive—Users must have all the scoped tags that are tagged within the relevant entity of the system.

Note

From version 3.5, if SBAC was enabled for any users before the upgrade, this setting will be enabled by default.

Define Distribution List Emails
Abstract

Learn more about defining a list of email addresses as distribution lists for Cortex XDR.

Define a list of email addresses Cortex XDR can use as distribution lists. The defined email addresses are used to send product maintenance, updates, and new version notifications. The email addresses are in addition to e-mails registered with your CSP account.

  • In the Email Contacts section, enter the email addresses you want to include in a distribution list. Make sure to select network-mapper-enter.png after each email address you enter.

Define XQL Configuration Settings
Abstract

Learn more about defining Cortex Query Language (XQL) configuration settings, which control your XQL queries.

The XQL Configuration settings control your Cortex Query Language (XQL) queries in the system. To make it easier for you to configure Case Sensitivity across Cortex XDR in one central area, you can configure case sensitivity (config case_sensitive = true | false) is applied throughout the application. By default, this setting is set to false and field values are evaluated as case insensitive. This setting overwrites any other default configuration except for BIOCs, which will remain case insensitive no matter what this configuration is set to.

Note

From Cortex XDR version 3.3, the default case sensitivity setting was changed to case insensitive (config case_sensitive = false). If you've been using Cortex XDR before this version was released, the default case sensitivity setting is still configured to be case sensitive (config case_sensitive = true).

Define Incident Mean Time to Resolve (MTTR)
Abstract

Learn more about defining the target incident Mean Time to Resolve (MTTR) applied according to the incident severity.

Define the target incident MTTR you want to be applied according to the incident severity.

  • In the Define the Incident target MTTR per incident severity section, enter within how many days and hours you want incidents resolved according to the incident severity Critical, High, Medium, and Low.

    The defined MTTR is used to display the Resolved Incident MTTR dashboard widgets.

Define the Impersonation Role
Abstract

Learn more about the type of role permissions granted to the Palo Alto Networks Support team when opening support tickets.

Define the type of role permissions granted to the Palo Alto Networks Support team when opening support tickets. By default, Palo Alto Networks Support is granted read-only access to your tenant.

  • In the Impersonation Settings section, define the level and duration of the permissions.

    • Select one of the following Role permissions:

      • Read-Only—Default setting, grants read-only access to your tenant.

      • Support related actions—Grants permissions to tech support file collection, dump file collection, investigation query, Correlation Rule, BIOC and IOC rule editing, alert starring, exclusion, and exception editing.

      • Full role permissions—No limitations are applied, grants full permissions to all actions and content on your tenant.

    • Set the Permission Reset Timeframe.

      If you selected Support related actions or Full role permissions in the Role field, set a specific timeframe for how long these permissions are valid. Select either 7 Days, 30 Days, or No time limitation.

    We recommend that Role permissions are granted only for a specific timeframe, and full administrative permissions is granted only when specifically requested by the support team.

  • Session Expiration—Enables you to define the number of hours after which the user login session will expire, and automatic logout for user inactivity. You can also define expiration time for the Cortex XDR dashboard.

  • Allowed Sessions—Enables you to define approved domains and approved IP address ranges through which access to Cortex XDR should be allowed.

    To ensure tenant stability, some of Palo Alto Networks' monitoring tools require external IP address access. When Approved IP ranges are Enabled, access to Palo Alto managed monitoring tools are allowed by default.

  • User Expiration—Enables you to deactivate an inactive user, and also set the user deactivation trigger period.

  • Approved Domains—Enables you to specify one or more domain names that can be used in your distribution lists.

  • Approved IP Ranges—If enabled, specify the IP address ranges from which you want to allow user access (login) to Cortex XDR. You can also choose to limit API access from specific IP addresses.
