Carbon Black App Control User Guide
- Preface
  This is your guide to day-to-day administration and security monitoring tasks: monitoring executable files on your network using App Control; configuring the App Control Server; managing computers running the App Control Agent; and managing App Control Console users.
- App Control Overview
- Using the Console
  This section covers the basics of using the Carbon Black App Control Console: how to log in and out, how to navigate in the user interface from the Home page and menu system, and how to view the information Carbon Black App Control makes available to you through tables, details pages, and dashboards.
- Managing Console Login Accounts
  This section describes how to create and manage login accounts for the Carbon Black App Control Console. It also describes how to define user roles that grant access to specified features, and in some cases limit this access by policy.
- Managing Computers
  This section describes the steps necessary to install Carbon Black App Control agents on computers. It also describes how to upgrade or uninstall agents, view the details agents provide to the Carbon Black App Control Console and manage operating system updates on agent-managed systems.
- Creating and Configuring Policies
  This section explains how to create policies and change their settings, including Enforcement Levels.
- Managing Virtual Machines
  This section explains how Carbon Black App Control efficiently manages virtual machines, called clones in the console, and the template computers on which they are based.
- File, Publisher, and Application Information
  This section describes the location and contents of file information in Carbon Black App Control. It also includes:
- Approving and Banning Software
  This section describes how to approve or ban software using Carbon Black App Control. It includes information about both global and local file approval.
- Deleting Files
  This section describes how to use the Carbon Black App Control Console to delete files on Windows endpoints.
- Reputation Approval Rules
  This section describes reputation approval rules, which can be used to automatically approve files based on the file and publisher trust ratings that Carbon Black File Reputation provides.
- Managing File-Signing Certificates
  This section describes advanced features for using file-signing certificates in Carbon Black App Control file monitoring and enforcement activities.
- Managing Devices
  This section describes features for tracking and control of storage devices detected on computers running the Carbon Black App Control Agent.
- Custom Software Rules
  Custom rules define actions you want the agent to take in response to file, directory, or process activity that matches conditions you specify. They may be used to optimize performance, protect file integrity, create a trusted file path for software distribution, or meet other special needs
- Memory Rules
  Memory Rules let you protect a process from being accessed or altered by other processes or users.
- Registry Rules
  This chapter describes Registry rules, which control what happens when there is an attempt to make changes in the Windows Registry at locations that match paths you specify. If you choose, you can limit enforcement of the rules to specified users and/or processes.
- Script Rules
  This chapter describes Script rules, which identify files to be tracked and managed as scripts by Carbon Black App Control. The Carbon Black App Control Server includes built-in script rules, and you can create custom rules to identify other scripts.
- YARA Rules
  Carbon Black App Control provides content-based inspection by using YARA rules, which enables more granular control of the security policy in your environment. YARA rules are descriptions of malware samples that can help you detect and classify malware in files. In a rule, the criteria for the rule is defined and tags are specified. When the rule is enabled, tags are assigned to files that meet the criteria for the rule.
- Expert Rules
  Expert rules are Custom, Memory, and Registry rules created with a special interface that provides many more options than the standard interface for these rules. They are intended for expert users working with Carbon Black Support or Technical Services.
- Rapid Configs
  This chapter describes Rapid Configs, which are sets of rules that can be used to accomplish tasks such as application optimization, operating system and application hardening, and approval of files delivered by software distribution systems.
- Event Rules
  There are Event rules, which allow you to specify an action to be performed when an event matches filters you define.
  - Enable, Disable, and Delete Event Rules
    You can enable, disable, or delete specific Event rules on either the Event Rules (table) page or the Edit Event Rule page.
    - Disable Processing of All Event Rules
      By default, the App Control Server is configured to process any enabled event rules. This means that the Enabled/Disabled/Simulate setting for each rule determines how and whether that rule functions. However, you can deactivate the event rule feature so that no event rules are processed.
    - Test a Rule before Enabling It
      Event rule actions, such as bans, approvals, and moving computers between policies, can cause serious security and operational issues if not properly configured. Because of this, it is strongly recommended that any new rule be run in Simulate only mode before it is fully enabled – this is one of the options on the Add Event Rule and Edit Event Rule pages.
  - Creating and Editing Event Rules
    You can create a new event rule by copying and modifying the settings of an existing rule or by creating the rule from scratch.
  - Sample Event Rules
    The Event Rules page, which you access by choosing Rules > Event Rules on the console menu, includes several sample rules. You can click on the View Details button to open the Event rule details page for any of these rules to see how they are specified.
- Endpoint Notifiers and Approval Requests
  This chapter describes the Carbon Black App Control features that involve interactions with endpoint users.
- Events, Alerts and Meters
  This section explains how to use Carbon Black App Control event reports and alerts to monitor file activity and other key operations on your network. It also describes tools for detecting propagation of files on your network and for keeping track of the number of times a specified file executes.
- Monitoring Change: Baseline Drift Reports
  This section describes how to use Baseline Drift Reports, which allow you to track changes in the inventory of files on systems running the Carbon Black App Control Agent.
- Advanced Threat Detection
  This section describes how you enable and use Carbon Black App Control’s Advanced Threat Indicators, and how you can monitor threats through events, file details, and alerts.
- Using and Customizing Dashboards
  Carbon Black App Control Dashboards are configurable pages containing compact windows called portlets, each of which provides access to Carbon Black App Control-related information or controls.
- Locating Files
  This section describes how to use the Find Files page to locate or verify the existence of specific executable files on computers running the Carbon Black App Control Agent. Find Files locates instances of files, not their listings in the File Catalog.
- System Configuration
  This section describes settings that enable you to configure and maintain your Carbon Black App Control Server installation. Access to the System Configuration page is available only to login accounts in the Administrators group or in customized groups with View System Configuration and Manage System Configuration check boxes selected.
- Unified Management of Multiple Servers
  If you have multiple Carbon Black App Control servers, you can centralize the management of those servers. Unified Management allows you to specify that one server can control many common management functions for any connected Carbon Black App Control servers.
- Monitoring System Health
  This section introduces the System Health page, which provides Carbon Black App Control administrators with the ability to monitor the health and performance of the Carbon Black App Control Server.
- Live Inventory SDK: Database Views
  In addition to the access provided to the Live Inventory of files and computers through the console, Carbon Black App Control provides public views into the database. You can create your own reporting and data analysis solutions through the use of these public views.
- Carbon Black App Control API
  The Carbon Black App Control API is intended for programmers who want to write code to interact with Carbon Black App Control, either using custom scripts or from other applications. It is a RESTful API that can be consumed over HTTPS protocol using any language that can create get URI requests and post/put JSON requests as well as interpret JSON responses.
- Carbon Black App Control Connector
  This section provides instructions for configuring and using the Connector, which integrates the Carbon Black App Control Server with one or more network security devices or services.

  The DasCLI.exe program, referred to as DASCLI, is an executable which provides Command Line Interface (CLI) access to the Carbon Black App Control Windows Agent. Messages are transmitted between DASCLI and the Agent.
- Diagnostic Files
  The Carbon Black App Control Console includes a page that displays certain diagnostic files for the Carbon Black App Control Server and its agents. These files can be useful when you are investigating issues in your Carbon Black App Control environment with the assistance of Carbon Black Support.
- Uploading Files from Agents
  This topic describes uploading files from agents.
- Exporting Data for External Analysis
  This section provides instructions for configuring and using Carbon Black App Control External Analytics, which enables the Carbon Black App Control Server to export data it collects from endpoints to external analysis tools.

Enable, Disable, and Delete Event Rules

You can enable, disable, or delete specific Event rules on either the Event Rules (table) page or the Edit Event Rule page.

On the Event Rules page, you can select one or more rules and either enable or disable them using the Action menu.

Note: You cannot select the Simulate Only option on this menu. To enable a rule in Simulate Only mode, use the Edit Event Rule page. For a sample work flow for Simulate only rules, see Test a Rule before Enabling It.

On the console menu, navigate to the Rules > Event Rules page.
The Event Rules page appears, showing the available rules and their status.
Select the check-box next to one or more rules in the table.
On the Action drop-down menu, select Enable or Disable and confirm your choice in the confirmation dialog.
The checked rules are enabled or disabled according to your menu choice.
To activate Simulate only mode, which allows you to see what the effect of an event rule might be without having it take the action specified in its definition, click the View Details button next to the rule whose status you want to change.
The Edit Event Rule page opens.
In the Status field, click the radio button for Enabled, Simulate Only, or Disabled.
Make any other changes to the rule properties, then click Save to stay on the page to monitor events processed by the rule, or Save & Exit to leave the page.

Note: If an event rule depends on a particular configuration of an analysis tool, such as an analysis environment with a specific operating system, and if that environment becomes unavailable, the rule is disabled automatically after waiting several minutes for the environment to become available again.

You can delete Event rules within the Event Rules page by selecting the checkbox next to one or more rules in the table, and clicking Delete from the Action drop-down menu.
