Group tasks are performed on the devices of the selected administration group. For more information on tasks, refer to Kaspersky Security Center documentation.

To create a group task:
1. Open Kaspersky Security Center Administration Console.
2. Do one of the following:
  - In the Administration Console tree, select the Managed devices folder to create a group task for all devices managed using Kaspersky Security Center.
  - In the Managed devices folder of the Administration Console tree, select the folder with the name of the administration group, which includes the required devices.
3. In the workspace, select the Tasks tab.
4. Click Create a task.
  The task creation wizard will start.
5. Select the required task and click Next.
6. Follow the instructions of the task creation wizard.

The task creation wizard allows you to configure the following settings:

IOC collection
To configure IOC collection:
1. In the IOC collection group of settings click Browse.
2. In the context menu, do one of the following:
  - Select the Browse for folder item to add a group of IOC files to the IOC collection.

  3. On the Areas tab, select the areas on protected device drives where to look for indicators of compromise.
    You can select one of the predefined areas, or specify the paths to the desired areas manually.
  4. On the Exclusions tab, select the Apply exclusions check box and specify the paths to the areas on the protected device drives that do not need to be scanned during the task execution.
  5. Click OK to save the changes and close the FileItem document scan settings window.
5. To configure additional settings for the selected RegistryItem IOC document:

Retrospective IOC Scan
Retrospective IOC Scan is an operation mode of the IOC Scan task, when Kaspersky Endpoint Agent searches for indicators of compromise based on the data received during a time interval specified by the user. This mode is intended for searching for indicators of compromise based on the data on network activity of protected devices. Kaspersky Endpoint Agent analyzes data in the operating system logs and in browsers on devices.

IOC (Indicator of Compromise) is a set of data about a malicious object or malicious activity.

The Retrospective IOC Scan mode is available only for Standard IOC Scan tasks.

To enable the Retrospective IOC Scan mode:
1. In the Retrospective IOC Scan group of settings enable the Perform Retrospective IOC Scan within the interval option.
2. Specify the time interval.
  During the task execution, the application analyzes data collected during the specified time interval, including the boundaries of the specified interval (from 00:00 on the start date until 23:59 on the end date). The default interval starts at 00:00 on the day preceding the task creation day and ends at 23:59 on the day when the task was created.
If during execution of the IOC Scan task with the Perform Retrospective IOC Scan within the interval option enabled the application does not find any data for the specified time interval to be analyzed, it does not inform about this. In this case, the application shows no indicators of compromise in the task completion report.
Application actions on IOC detection
To configure Kaspersky Endpoint Agent actions on IOC detection:
1. In the Actions section, select the Take response actions when an Indicator of Compromise is detected check box.
2. Select the Isolate device from the network check box to enable network isolation of the device on which indicator of compromise is detected by Kaspersky Endpoint Agent.
3. Select the Run Endpoint Protection Platform scan of critical areas on the device check box so that Kaspersky Endpoint Agent sends a command to EPP application to scan critical areas on all the devices of the administration group on which indicators of compromise are detected.
When configuring the task settings in Kaspersky Security Center Administration Console, the Do not perform actions on critical system files check box is available only if the Quarantine and delete response action is selected for the task (this setting can be configured only in Kaspersky Security Center Web Console).
Task start schedule
To configure the schedule settings for IOC Scan task:
1. In the Tasks schedule section, select the Run by schedule check box.
2. In the Frequency list select one of the following options to run IOC Scan tasks: At specified time, Every hour, Every day, Every week or On application launch.
3. If you select the At specified time option, specify the day and time to start the task in the Run by schedule section.
4. If you select one of the following options: Every hour, Every day or Every week, configure the following settings in the Run by schedule section:
  1. In the Every list, select the task run frequency. For example, once a day or twice a week on Tuesdays and Thursdays.
  2. In the Start time and Start date lists, select the date and time from which the schedule applies.
5. To configure advanced schedule settings, click the Advanced button and perform the following actions in the Advanced window:
  1. If you want to set a maximum timeout for the task execution, select the Stop tasks that run longer than check box and specify the number of hours and minutes after which the task will automatically terminate.
  2. If you want the task schedule to be valid until a certain date, select the Cancel schedule from check box and specify the expiration date for the schedule.
  3. If you want the application to start IOC Scan tasks that were not completed on time as soon as possible, select the Run missed tasks check box.
  4. If you want to avoid simultaneous access of a large number of workstations to the Administration Server as well as to run the task on workstations not precisely according to the schedule, but randomly within a certain time interval, select the Randomize the task start time within the interval check box and specify the start interval in minutes.
  5. Click OK.
Running the task from a Kaspersky Security Center user account
To select Kaspersky Security Center user account, under which you want to run the task,

perform one of the following actions in the group of settings for selecting an account to start the task:
- Select the default account and click Next.
- Enter the name and password of the user whose account permissions will be used to start the task.
Task name
The task name cannot be longer than 100 characters long and cannot contain special characters ("* <>? \: |).

Identifiers of all IOC files that are used in the same IOC Scan task must be unique. The presence of IOC files with the same identifier can affect the correctness of the task execution results.

If, when creating the IOC Scan task, you upload some IOC files that are not supported by Kaspersky Endpoint Agent then when the task starts, the application will use only supported IOC files.

Semantic errors and IOC terms and tags in IOC files that are not supported by the application do not cause the task execution errors. The application just does not detect matches in such sections of IOC files.
