Managing assets

Assets represent the computers of the organization. You can add assets to KUMA; in that case, KUMA automatically adds asset IDs when enriching events, and when you analyze events, you can get additional information about computers in the organization.

You can add assets to KUMA in the following ways:

• Import assets:
  • From the MaxPatrol report.
  • On a schedule from Kaspersky Security Center and KICS for Networks.

    By default, assets are imported every 12 hours, this frequency can be configured. On-demand import of assets is also possible; such on-demand import does not affect the scheduled import time. From the Kaspersky Security Center database, KUMA imports information about devices with installed Kaspersky Security Center Network Agent that has connected to Kaspersky Security Center, that is, has a non-empty 'Connection time' field in the SQL database. KUMA imports the following information about the computer: name, address, time of connection to Kaspersky Security Center, information about hardware and software, including the operating system, as well as vulnerabilities, that is, information received from Kaspersky Security Center Network Agents.

• Create assets manually through the web interface or via the API.

  You can add assets manually. In this case, you must manually specify the following information: address, FQDN, name and version of the operating system, hardware information. Information about the vulnerabilities of assets cannot be added through the web interface. You can provide information about vulnerabilities if you add assets using the API.

You can manage KUMA assets: view information about assets, search for assets, add, edit or delete assets, and export asset data to a CSV file.

Asset categories

You can categorize the assets and then use the categories in filter conditions or correlation rules. For example, you can create alerts of a higher severity level for assets from a higher-severity category. By default, all assets fall into the Uncategorized assets category. A device can be added to multiple categories.

By default, KUMA assigns the following severity levels to asset categories: Low, Medium, High, Critical. You can create custom categories, categories can be nested.

Categories can be populated in the following ways:

• Manually
• Active: dynamic if the asset meets the specified conditions. For example, the moment the asset is upgraded to a specified OS version or placed in a specified subnet, the asset is moved to the specified category.
  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.

     Categorization filter operands and operators

     Operand	Operators	Comment
     Build number	>, >=, =, <=, <
     OS	=, like	The "like" operator ensures that the search is not case sensitive.
     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	=, like	The "like" operator ensures that the search is not case sensitive.
     CVE	=, in	The "in" operator lets you specify an array of values.
     Software	=, like
     CII	in	More than one value can be selected.
     Anti-virus databases last updated	>=,<=
     Last update of the information	>=,<=
     Protection last updated	>=,<=
     System last started	>=,<=
     KSC extended status	in	Extended status of the device. More than one value can be selected.
     Real-time protection status	=	Status of Kaspersky applications installed on the managed device.
     Encryption status	=
     Spam protection status	=
     Anti-virus protection status of mail servers	=
     Data Leakage Prevention status	=
     KSC extended status ID	=
     Endpoint Sensor status	=
     Last visible	>=,<=

  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—When a correlation rule is triggered, the asset is moved to the specified group.

In KUMA, assets are categorized by tenant and by category. Assets are arranged in a tree structure, where the tenants are located at the root, and the asset categories branch from them. You can view the tree of tenants and categories in the Assets → All assets section of the KUMA web interface. When a tree node is selected, the assets assigned to it are displayed in the right part of the window. Assets from the subcategories of the selected category are displayed if you specify that you want to display assets recursively. You can select the check boxes next to the tenants whose assets you want to view.

To open the context menu of a category, hover the mouse cursor over the category and click the ellipsis icon that is displayed to the right of the category name. The following actions are available in the context menu:
