Configuring the display of a link to a Kaspersky Endpoint Detection and Response detection in the KUMA alert

Expand all | Collapse all

When Kaspersky Endpoint Detection and Response detections are received, KUMA creates an alert for each detection. You can configure the display of a link to a Kaspersky Endpoint Detection and Response detection in KUMA alert information.

You can configure the display of a detection link if you use only one Central Node server in Kaspersky Endpoint Detection and Response. If Kaspersky Endpoint Detection and Response is used in a distributed solution mode, it is impossible to configure the display of the links to Kaspersky Endpoint Detection and Response detections in KUMA.

To configure the display of a link to a detection in KUMA alert details, you need to complete steps in the Kaspersky Endpoint Detection and Response web interface and KUMA.

In the Kaspersky Endpoint Detection and Response web interface, you need to configure the integration of the application with KUMA as a SIEM system. For details on configuring integration, refer to the Kaspersky Anti Targeted Attack Platform documentation, Configuring integration with a SIEM system section.

Configuring the display of a link in the KUMA Console includes the following steps:

1. Adding an asset that contains information about the Kaspersky Endpoint Detection and Response Central Node server from which you want to receive detections, and assigning a category to that asset.
2. Creating a correlation rule.
3. Creating a correlator.

You can use a pre-configured correlation rule. In this case configuring the display of a link in the KUMA Console includes the following steps:

1. Creating a correlator.

   Select the [OOTB] KATA Alert correlation rule.

2. Adding an asset that contains information about the Kaspersky Endpoint Detection and Response Central Node server from which you want to receive detections and assigning a category KATA standAlone to that asset.

Step 1. Adding an asset and assigning a category to it

First, you need to create a category that will be assigned to the asset being added.

To add a category:

1. In the KUMA Console, select the Assets section.
2. On the All assets tab, expand the category list of the tenant by clicking next to its name.
3. Select the required category or subcategory and click the Add category button.

   The Add category details area appears in the right part of the web interface window.

4. Define the category settings:
   1. In the Name field, enter the name of the category.
   2. In the Parent field, indicate the position of the category within the categories tree hierarchy. To do so, click the button and select a parent category for the category you are creating.

      Selected category appears in Parent fields.

   3. If required, define the values for the following settings:
      • Assign a severity to the category in the Priority drop-down list.

        The specified severity is assigned to correlation events and alerts associated with the asset.

      • If required, add a description for the category in the Description field.
      • In the Categorization kind drop-down list, select how the category will be populated with assets. Depending on your selection, you may need to specify additional settings:
        • Manually—assets can only be manually linked to a category.
        • Active—assets will be assigned to a category at regular intervals if they satisfy the defined filter.
          1. In the Repeat categorization every drop-down list, specify how often assets will be linked to a category. You can select values ranging from once per hour to once per 24 hours.

             You can forcibly start categorization by selecting Start categorization in the category context menu.

          2. In the Conditions settings block, specify the filter for matching assets to attach to an asset category.

             You can add conditions by clicking the Add condition buttons. Groups of conditions can be added by using the Add group buttons. Group operators can be switched between AND, OR, and NOT values.

             Using time values

             Some conditions, for example, Anti-virus databases last updated or System last started, use date and time as the operand value. For these conditions, you can use an exact date and time or a relative period.

             To specify a date and time value:

             1. Select an operand, an operator and click the date field.
             2. Do one of the following:
                • Select the exact date in the calendar.

                  By default, the current time is automatically added to the selected date, with millisecond precision. Changing the date in the calendar does not change the specified time. The date and time are displayed in the time zone of the browser. If necessary, you can edit the date and time in the field.

                • In the Relative period list, select a relative period.

                  The period is calculated relative to the start time of the current categorization and takes into account asset information that is up-to-date at that moment. For example, for the condition Anti-virus databases last updated, you can select 1 hour and the >= operator to periodically link to the category those assets for which the anti-virus databases have not been updated for more than 1 hour before the start of categorization.

                • In the date and time field, enter a value manually.

                  You can enter an exact date and time in the DD.MM.YYYY HH:mm:ss.SSS format for the Russian localization and YYYY-MM-DD HH:mm:ss.SSS for the English localization or a relative period as a formula. You can also combine these methods if necessary.

                  If you do not specify milliseconds when entering the exact date, 000 is substituted automatically.

                  In the relative period formulas, you can use the now parameter for the current date and time and the interval parameterization language: +, -, / (rounding to the nearest), as well as time units: y (year), M (month), w (week), d (day), h (hour), m (minute), s (second).

                  For example, for the Information last updated condition, you can specify the value now-2d with the operator >= operator and the value now-1d with the >= operator to regularly link assets to the category if those assets had information updated during the day before the categorization was started; alternatively, you can specify the value now/w with the <= operator to regularly link assets to the category if those assets had information updated between the beginning of the first day of the current week (00:00:00:000 UTC) and now.

                  KUMA stores time values in UTC, but in the user interface time is converted to the time zone of your browser. This is relevant to the relative periods: Today, Yesterday, This week, and This month. For example, if the time zone in your browser is UTC+3, and you select Today as the period, the category will cover assets from 03:00:00.000 until now, not from 00:00:00.000 until now.

                  If you want to take your time zone into account when selecting a relative period, such as Today, Yesterday, This week, or This month, you need to manually add a time offset in the date and time field by adding or subtracting the correct number of hours. For example, if your browser's time zone is UTC+3 and you want the categorization to cover the Yesterday period, you need to change the value to now-1d/d-3h. If you want the categorization to cover the Today period, change the value to now/d-3h.

          3. Use the Test conditions button to make sure that the specified filter is correct. When you click the button, you should see the Assets for given conditions window containing a list of assets that satisfy the search conditions.
        • Reactive—the category will be filled with assets by using correlation rules.
5. Click the Save button.

To add an asset:

1. In the KUMA Console, select the Assets section.
