Adding an asset category

To add an asset category:

1. Open the Assets section in the KUMA web interface.
2. Open the category creation window by doing the following:
   1. In the list of tenants, expand the tenant to which you want to add the new category.
   2. Hover over the parent category and do one of the following:
      • Click the plus () icon.
      • In the menu () select Add subcategory.

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

3. Add information about the category:
   • In the Name field, enter the name of the category. The name must contain 1 to 128 Unicode characters.
   • If necessary, change the category in the Parent drop-down list.
   • The Tenant field displays the tenant whose structure contains your selected parent category. You cannot change the previously selected tenant.
   • If necessary, change the severity of the category in the Severity drop-down list. The default value is Low.
   • If necessary, in the Description field, you can add a note consisting of up to 256 Unicode characters.
4. 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. If an asset no longer matches the specified filter, such an asset is unlinked from the category, regardless of whether the assets were added automatically or manually.

     Active category of assets

     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. Under Conditions, 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.

        Categorization filter operands and operators

        Operand	Operators	Comment
        Build number	=, ilike
        OS	=, ilike	The ilike operator makes the search case-insensitive.
        IP address	inSubnet, inRange	The IP address is indicated in CIDR notation (for example: 192.168.0.0/24). When the inRange operator is selected, you can indicate only addresses from private ranges of IP addresses (for example: 10.0.0.0–10.255.255.255). Both addresses must be in the same range.
        FQDN	=, ilike	The ilike operator makes the search case-insensitive.
        CVE	=, in	The in operator lets you specify an array of CVE (Common Vulnerabilities and Exposures) IDs.
        CVSS	>, >=, =, <=,<	Severity level of CVE vulnerabilities on the asset. The CVSS parameter takes values from 0 to 10. Not applicable to vulnerabilities from Kaspersky Security Center.
        CVE count	>, >=, =, <=, <	The number of unique vulnerabilities with the CVE attribute for the asset. Vulnerabilities without CVEs do not count towards this figure. For categorization by the number of CVEs of a certain severity level, you can use a combined condition. For example: CVE count >= 1 AND CVSS >= 6.5
        Software	=, ilike	Categorization by software installed on the asset. The ilike operator makes the search case-insensitive.
        Software version	=, ilike, in	Categorization by version (build) number of the software installed on the asset. The ilike operator makes the search case-insensitive.
        CII	in	More than one value can be selected.

        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, the Assets for given conditions window containing a list of assets that satisfy the search conditions will be displayed.
   • Reactive—the category will be filled with assets by using correlation rules.
5. Click Save.

The new category will be added to the asset categories tree.
