Résolution

The Threat Defense console is divided into six sections:

  • Dashboard
  • Protection
  • Zones
  • Devices
  • Reports
  • Settings

Click a section for more information.

The Dashboard displays on login to the Dell Threat Defense console. The Dashboard provides an overview of threats in the environment and provides access to different console information from one page.

Dashboard

Threat Statistics

Threat Statistics provide the number of threats that are found within the Last 24 Hours and the Total for your organization. Clicking a Threat Statistic takes you to the Protection page and displays the list of threats that are related to that statistic.

  • Running Threats: Files that are identified as threats that are currently running on devices in your organization.
  • Auto-Run Threats: Threats that are set to run automatically.
  • Quarantined Threats: Threats that are quarantined within the last 24 hours and the total.
  • Unique to Cylance: Threats that are identified by Cylance but not by other anti-virus sources.

Protection Percentages displays an overview for Threat Protection and Device Protection.

Threat Protection

  • Threat Protection: The percentage of threats you have taken action on (Quarantine, Global Quarantine, Waive, and Safe Lists).

Device Protection

  • Device Protection: The percentage of devices associated with a policy that has Auto-Quarantine enabled.

Threats by Priority displays the total number of threats that require an action (Quarantine, Global Quarantine, Waive, and Safe Lists). The threats are grouped by priority (High, Medium, and Low).

Threats by Priority

A threat is classified as Low, Medium, or High based on the number of the following attributes it has:

  • The file has a Cylance score greater than 80.
  • The file is currently running.
  • The file has been run previously.
  • The file is set to auto run.
  • The priority of the zone where the threat was found.

Threat classifications

Threat Events displays a line graph with the number of threats that are discovered over the last 30 days. Lines are color coded for Unsafe, Abnormal, Quarantined, Waived, and Cleared files.

Threat Events

Threat Classifications displays a heat map of threat types that are found in an environment. Clicking an item jumps the administrator to the Protection section and displays a list of threats of that type.

Threat Classifications

Top Five Lists display Unsafe Threats in an environment that have not been acted upon. Most of the time these lists should be empty.

Top Five Lists

The Protection section is used to evaluate and manage threats affecting devices using Dell Threat Defense. Select the appropriate step below for more information.

Protection

The Dell Threat Defense console provides an in-depth evaluation on "unsafe" or "abnormal" files to help administrators properly mitigate threats in their environment.

To evaluate a file:

  1. In the console, click the Protection tab.

Protection

  1. Under Protection, click a threat to obtain more information.

Evaluating threat stats

Cylance Score: A score of 1 (limited) -100 (high) is assigned by Cylance based on threat attributes.

Quarantined by users in [Tenant]: What actions on file have been taken by users within the environment (Tenant).

Quarantined by all Cylance users: What actions on the file have been taken by users within all Cylance environments.

Classification: General identification of file/threat.

Threat timestamp

First Found: When the file was first found in the environment

Last Found: When the file was last found in the environment

Threat Actions

Global Quarantine: Adds a file to the global quarantine list for the environment. Any time the file appears on a device it will automatically be quarantined in the \q folder.

Safe: Adds a file to the safe list for an environment. If a file is currently quarantined, it will automatically place it back in its original location.

SHA256: The 256 cryptographic hash used to identify the file/threat. An administrator can click the hash to perform a Google search of known occurrences.

MD5: The 128 cryptographic hash used to identify the file/threat. An administrator can click the hash to perform a Google search of known occurrences.

Note: A file/threat may have only known SHA256 or MD5 occurrences. Both are listed to ensure that a comprehensive view is given on the file/threat.

Download File: Allows an administrator to download the file for further evaluation and testing.

Threat Confidence Levels

Cylance Score: A score of 1 (limited) -100 (high) is assigned by Cylance based on threat attributes.

AV Industry: Determines if third-party anti-virus engines identify the file as a threat by checking the virustotal.com index.

Search Google: Searches Google for the hashes and filename for more information about the file/threat.

There may be files that are incorrectly identified as threats within an environment. Administrators can add them to the global safe list to prevent them from being quarantined. Any file that is quarantined before being safe-listed returns to its original location.

Note: Before safe listing an item, it is highly recommended to evaluate a threat.

To safe list a file:

  1. In the console, click the Protection tab.

Protection

  1. Under Protection, check the threat to be safe-listed and then click Safe.

Safe

  1. From the Action Confirmation pop-up, select a file Category from the drop-down menu. This helps with file/threat classification.

Action Confirmation

  1. Populate a Reason for the safe-listing. This provides visibility across the environment.
  2. Click Yes to confirm safe-listing.
Note:
  • Previous safe-listed items can be reviewed and modified at any time under the Settings > Global List section of the Dell Threat Defense console.
  • Files can be safe-listed at the global, policy, or device level. In our example, we safe-listed at the global level.

An administrator may proactively quarantine a file from targeting their devices by adding it to the global quarantine list.

To globally quarantine a file:

  1. In the console, click the Protection tab.

Protection

  1. Under Protection, check the threat to be safe-listed and then click Global Quarantine.

Global Quarantine

  1. In the Action Confirmation pop-up, populate the Reason for the quarantine. This helps provide visibility to other administrators and zone managers.
  2. Click Yes to confirm Global Quarantine.
Note:
  • Previous quarantine items can be reviewed and modified at any time under the Settings > Global List section of the Dell Threat Defense console.
  • Files can be safe-listed at the global or device level. In our example, we quarantined at the global level.

Zones are used to create containers responsible for the management and organization of devices. For more information, reference How to Manage Zones in Dell Threat Defense.

Zones

The Devices section is used to add, manage, and report on devices (agents) within an environment using Dell Threat Defense. The most common actions in this section are Downloading the Installer, Obtaining an Installation Token, Enabling Verbose Logging, and Removing a Device. Click the appropriate step for more information.

Devices

The Dell Threat Defense installer is available directly within the tenant. For steps on how to download Dell Threat Defense, reference How to Download Dell Threat Defense.

In order to install Dell Threat Defense on a device, a valid installation token must be obtained from tenant. For steps on how to obtain an installation token, reference How to Obtain an Installation Token for Dell Threat Defense.

By default, devices contain limited logging for Dell Threat Defense. It is highly recommended to enable verbose logging on a device before troubleshooting or contacting Dell Data Security ProSupport. For more information, reference Dell Data Security International Support Phone Numbers. For more information about how to enable verbose logging, reference How to Enable Verbose Logging in Dell Threat Defense.

Devices are not automatically removed from the Dell Threat Defense console during uninstall. An administrator must manually remove the device from the tenant console. For more information, reference How to Remove a Device from the Dell Threat Defense Administration Console.

The Reports offer Summary and Detail reports to provide overviews and details that are related to devices and threats in an organization.

Reports display threats in an event-based manner. An event represents an individual instance of a threat. For example, if a particular file (specific hash) is located in three different folder locations on the same device, the threat event count will equal 3. Other areas of the Console, such as the Threat Protection page, may display threat counts for a particular file based on the number of devices on which the file is found, regardless of how many instances of the file are present on any given device. For example, if a particular file (specific hash) is located in three different folder locations on the same device, the threat count will equal 1.

Reporting data is refreshed approximately every three minutes. Click Threat Defense Overview, Threat Event Summary, Device Summary, Threat Events, or Devices for more information.
