To create a more personalized user experience, Cortex XDR enables you to define your Server and Security Settings.

From the Cortex XDR management console, navigate to SettingsConfigurationsGeneralServer Settings to define the following:

Define Keyboard Shortcuts

Select the keyboard shortcut for the Cortex XDR capabilities.

  • In the Keyboard Shortcuts section, change the default settings for:

    • Artifact and Asset Views

    • Quick Launcher

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

Select 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

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

  • In the Timestamp Format section, select the timestamp format in which you want to display your Cortex XDR data.

    Note

    The setting is configured per user and not per tenant.

Define 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

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

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 true and field values are evaluated as case sensitive. This setting overwrites any other default configuration except for BIOCs, which will remain case insensitive no matter what this configuration is set to.

Define Incident Mean Time to Resolve (MTTR)

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

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.

Set up Session Security Settings

The session security settings include:

  • 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.

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

  1. From the Cortex XDR management console, select SettingsConfigurationsSecurity Settings.

  2. Under Session Expiration, define the following:

    1. User Login Expiration—Select the number of session hours (1 - 24 hours) after which the user login should expire.

    2. Enable Auto Logout—If desired, enable automatic logout, and then select the required period of user inactivity (10 - 30 minutes).

    3. Dashboard Expiration—Select either 7 Days or As user login expiration (hours) to define the timing of the dashboard expiration.

  3. Under Allowed Sessions, define the following:

    1. Approved Domains—Select Enabled or Disabled. If enabled, specify the domains from which you want to allow the user access to Cortex XDR . You can add or remove domains as necessary.

    2. Approved IP Ranges—Select Enabled or Disabled. If enabled, specify the IP ranges from which you want to allow the user access to Cortex XDR . You can add or remove IP CIDR addresses as necessary.

  4. Under User Expiration, define if you want to Deactivate Inactive User. By default, user expiration is Disabled, when Enabled enter the number of days after which inactive users should be deactivated.

  5. Under Allowed Domains, specify one or more domain names that users in your organization can be used in your Define Distribution List Emails. For example, when generating a report, ensure the reports are not sent to email addresses outside your organization.
