Starting Kaspersky Security Center tasks automatically

Kaspersky Security Center tasks can be started automatically by Correlators. When certain conditions are met, the correlator activates response rules that contain the list of Kaspersky Security Center tasks to start and identify the relevant assets.

To configure Response resource that can be used by Correlators to start Kaspersky Security Center task automatically:

1. In the KUMA web interface, select Resources → Response.
2. Click the Add response button and set parameters as described below:
   • In the Name field enter the resource name that will let you identify it.
   • In the Type drop-down list, select ksctasks (Kaspersky Security Center tasks).
   • In the Kaspersky Security Center task drop-down list, select the tasks that must be run when the correlator linked to this response resource is triggered.

     You can select several tasks. When a response is activated, it picks only the first task from the list of the selected tasks that match the relevant asset. The rest of the matching tasks are disregarded. If you want to start multiple tasks based on one condition, you need to create multiple response rules.

   • Under Event field, select the event fields that will trigger the correlators. Possible values:
     • SourceAssetID
     • DestinationAssetID
     • DeviceAssetID
3. If necessary, in the Workers field specify the number of response processes that can be run simultaneously.
4. If necessary, use the Filter settings block to specify the conditions under which events will be processed by the created resource. You can select an existing filter resource from the drop-down list or create a new filter.

   Creating a filter in resources

   1. In the Filter drop-down list, select Create new.
   2. If you want to keep the filter as a separate resource, select the Save filter check box.

      In this case, you will be able to use the created filter in various services.

      This check box is cleared by default.

   3. If you selected the Save filter check box, enter a name for the created filter resource in the Name field. The name must contain from 1 to 128 Unicode characters.
   4. In the Conditions settings block, specify the conditions that the events must meet:
      1. Click the Add condition button.
      2. In the Left operand and Right operand drop-down lists, specify the search parameters.

         Depending on the data source selected in the Right operand field, you may see fields of additional parameters that you need to use to define the value that will be passed to the filter. For example, when choosing active list you will need to specify the name of the active list, the entry key, and the entry key field.

      3. In the operator drop-down list, select the relevant operator.

         Filter operators

         • =—the left operand equals the right operand.
         • <—the left operand is less than the right operand.
         • <=—the left operand is less than or equal to the right operand.
         • >—the left operand is greater than the right operand.
         • >=—the left operand is greater than or equal to the right operand.
         • inSubnet—the left operand (IP address) is in the subnet of the right operand (subnet).
         • contains—the left operand contains values of the right operand.
         • startsWith—the left operand starts with one of the values of the right operand.
         • endsWith—the left operand ends with one of the values of the right operand.
         • match—the left operand matches the regular expression of the right operand. The RE2 regular expressions are used.
         • hasBit—checks whether the left operand (string or number) contains bits whose positions are listed in the right operand (in a constant or in a list).
         • hasVulnerability—checks whether the left operand contains an asset with the vulnerability and vulnerability severity specified in the right operand.
         • inActiveList—this operator has only one operand. Its values are selected in the Key fields field and are compared with the entries in the active list selected from the Active List drop-down list.
         • inDictionary—checks whether the specified dictionary contains an entry defined by the key composed with the concatenated values of the selected event fields.
         • inCategory—the asset in the left operand is assigned at least one of the asset categories of the right operand.
         • inActiveDirectoryGroup—the Active Directory account in the left operand belongs to one of the Active Directory groups in the right operand.
         • TIDetect—this operator is used to find events using CyberTrace Threat Intelligence (TI) data. This operator can be used only on events that have completed enrichment with data from CyberTrace Threat Intelligence. In other words, it can only be used in collectors at the destination selection stage and in correlators.
      4. If necessary, select the do not match case check box. When this check box is selected, the operator ignores the case of the values.

         The selection of this check box does not apply to the InSubnet, InActiveList, InCategory or InActiveDirectoryGroup operators.

         This check box is cleared by default.

      5. If you want to add a negative condition, select If not from the If drop-down list.
      6. You can add multiple conditions or a group of conditions.
   5. If you have added multiple conditions or groups of conditions, choose a search condition (and, or, not) by clicking the AND button.
   6. If you want to add existing filters that are selected from the Select filter drop-down list, click the Add filter button.

      You can view the nested filter settings by clicking the button.

5. Click Save.

The Response resource is created. It can now be linked to a Correlator that would trigger it, starting a Kaspersky Security Center task as a result.
