Shield Events

Box Shield must be purchased and enabled on a Box enterprise in order to take advantage of the advanced security offerings outlined below.

Shield threat detection delivers context-rich alerts on potential threats, such as compromised accounts and data theft, based on anomalous user behavior.

The possible alerts produced by Shield are for:

Suspicious locations
Suspicious sessions
Anomalous downloads
Malicious content

All Shield threat detection alert events are produced within the enterprise event stream. These events follow the standard event object schema and the event_type value is set to SHIELD_ALERT.

Information about the specific type of shield alert that triggered the event will be supplied within the additional_details object.

A suspicious locations alert is produced when when Shield detects a user accessing content from an unusual, excluded geographic location, or 'host' IP address. It can be identified by the Suspicious Locations value within additional_details.shield_alert.rule_category.

The additional_details payload will provide the following details:

A suspicious sessions alert is produced when Shield detects a user accessing content in a session characterized by unusual user-agent strings, unusual IDs, uncommon types of applications, new IP addresses, and an improbably rapid change in the person's log-in location.

Smart Access enables Box Admins to define and enforce classification-based access policies to control access and prevent the unintentional leakage of sensitive content.

Smart Access policies can be configured in enforced or monitoring mode. In all event types, a field named controlMode appears to say whether the policy is in enforced or monitoring mode.

If an admin creates a Shield access policy that enforces download or print restriction and an end user is blocked from downloading or printing a file, an event is produced within the enterprise event stream. If the access policy is set to monitor potential download and print violations, events will also be generated when a user is viewing a folder with a file restricted from download or print, viewing a file in preview that is restricted from download or print, and when a user requests to download a file through the API that is restricted from download or print. These events follow the standard event object schema and the event_type value set to SHIELD_DOWNLOAD_BLOCKED.

If downloading is blocked, the additional-details payload of the SHIELD_DOWNLOAD_BLOCKED event will provide the below details.

For the Box Web App, the additional_details payload will provide the following details:

"additional_details": {
  "shield_download_enforcement": {

Admins, please note that you may see two enterprise events instead of one when a justification is chosen from the share modal. For example, one SHIELD_EXTERNAL_COLLAB_INVITE_BLOCKED_MISSING_JUSTIFICATION event and one SHIELD_EXTERNAL_COLLAB_INVITE_JUSTIFIED event.

If a 3rd-party application, including published custom applications with which your organization is integrated, is restricted from downloading a file or a folder, an event is produced within the enterprise event stream. These events follow the standard event object schema, with the event_type value set to SHIELD_DOWNLOAD_BLOCKED.

For 3rd-party applications, the additional_details payload will provide the following details:

"additional_details": {
  "shield_download_enforcement": {

      "type": "file",

If download of a file or folder is restricted via the FTP protocol, an event is produced within the enterprise event stream. These events follow the standard event object schema, with the event_type value set to SHIELD_DOWNLOAD_BLOCKED.
