Overview

Endpoint monitoring uses the Code42 app to capture file activity on user devices in real time, helping you track user behavior to identify potential data leaks or security problems.

  • Code42's file exfiltration detection captures file activity anywhere on a user's device, not just within the user's backup file selection, related to removable media, cloud services, uploads and downloads via web browsers and other applications, and file restores. It also searches contents of files selected for backup for specified text patterns.
  • Forensic File Search reports on all file activity on a device, which enables you to search file metadata to gain a clearer understanding of file activity throughout the organization.

Endpoint monitoring types

Enabling endpoint monitoring in your Code42 environment allows you to detect the following categories of potential file exfiltration activity:

  • Removable media: Monitors file activity on removable media, such as USB drives or SD cards.
  • Cloud service: Monitors file activity in folders on the device used for syncing with cloud services, including Box, Box Drive (Mac only), Dropbox, Google Backup and Sync, Apple iCloud, and Microsoft OneDrive.
  • Application activity: Identifies files opened in apps commonly used for uploading and downloading files, such as a web browser, Slack, FTP client, or curl.
  • File restore: Monitors files restored through the Code42 app and the administration console, both by users and administrators.
  • Pattern matching: Checks for the existence of known malicious files or patterns of sensitive data based on YARA rules for text (non-binary) files included in the user's backup file selection.
  • Forensic File Search: Provides detailed visibility about file activity on user devices (including files not selected for backup) and in cloud services such as Google Drive and Microsoft OneDrive. See Forensic File Search use cases for more details.

Considerations

  • Code42 recommends only enabling endpoint monitoring in a small, test organization at first. If your Code42 environment contains more than 5,000 users, contact your Customer Success Manager (CSM) for assistance creating a deployment strategy.
  • Most endpoint monitoring types listed above are supported for Windows and Mac devices only. Forensic File Search is the only type also supported on Linux devices.
  • If Compliance Settings are activated for an organization, you cannot enable endpoint monitoring for that organization or any of its child organizations that inherit settings. Parent and sibling organizations are not affected.
Google Drive File Stream activity not detected by endpoint monitoring
Google's Drive File Stream retrieves files by mounting a temporary internal drive partition on the user's device and streaming files to the temporary drive. The Code42 app only monitors file movement to external drives, so it does not detect this activity.

Before you begin

  1. Ensure your Code42 environment meets the following requirements:
  2. Create a test organization, and then add a small number of test users to use in the steps below for initial endpoint monitoring testing. Alternatively, use the Change Organization command to move a small number of existing users into the test organization.

Enable endpoint monitoring for file exfiltration detection

Step 1: Lock archive encryption key settings

Endpoint monitoring requires standard archive encryption. Before enabling endpoint monitoring for an organization, you must lock the Archive Encryption Key setting to prevent users or administrators from changing it later.

Disabled inheritance
If you disable inheritance for an organization, that organization is not affected by changes to its parent organization.
  1. Sign in to the administration console.
  2. Go to Organizations > Active.
  3. Select an organization.
  4. From the action menu, select Device Backup Defaults.
  5. In the General section, deselect Use device defaults from parent.
  6. Select the Security tab.
  7. In the Archive Encryption Key section:
    1. Deselect Use default archive encryption key setting.
    2. Verify that Standard is selected.
    3. Click the Lock icon to prevent users from changing this setting.
    4. Review the confirmation message and click OK.
  8. Click Save.

Step 2: Enable endpoint monitoring for organizations

Start with a test organization
Code42 recommends enabling endpoint monitoring in a test organization first to ensure settings are properly configured to capture the user activity you want to monitor. Once you see the desired results with a small number of users, then start enabling endpoint monitoring one organization at a time.
  1. Sign in to the administration console.
  2. Select Organizations > Active.
  3. Select an organization.
  4. From the action menu, select Edit.
  5. Select Endpoint Monitoring.
  6. Deselect Inherit settings from parent, if necessary.
Disabled inheritance
If you disable inheritance for an organization, that organization is not affected by changes to its parent organization.
  1. Select one or more detection types to enable them.
  2. Click Save to immediately apply your changes to all devices in this organization and all of its inheriting child organizations.

Optional configuration steps

Advanced settings
Steps 3 - 6 below are optional configuration settings, and are not required to start capturing file activity. If you want to configure any of these items to override the Code42 defaults, click the + icon next to each step for detailed instructions.

Step 3: Configure pattern matching

Step 4: Enable automatic file scan for removable media

Step 5: Exclude paths from monitoring

Step 6: Enable automatic file scanning of cloud folders

Review file activity

Details of monitored exfiltration activity are available in both the Investigation section of the Code42 administration console and in the Code42 app for Splunk.

Advanced search options
If you are licensed for Code42 Forensic File Search with the endpoint data source, user activity for Cloud Folders, Removable Media, and Application Activity is also available via the Investigation > Forensic Search section of the administration console.

Exposure filters in Forensic File Search introduce more advanced search options, and also display some file activity details in the administration console that were previously only available via CSV export. For more details, see the Forensic File Search reference guide

From the administration console

  1. Sign in to the administration console.
  2. Select Investigation > User Activity.
  3. Enter a username.
  4. Enter a date range.
  5. Click Search.
  6. Review the Activity Results.
  7. For more details, select the action menu in the upper-right of any chart and select Export CSV. The exported file contains extensive details about the file activity. 

Permissions for Investigation access
The Customer Cloud Admin role includes access to the Investigation section of the administration console automatically. To grant access to a user with a different role, assign the Security Center User role.  

If file exfiltration detection is included in your product plan but you can’t access the Investigation section of the administration console, go to My Profile to ensure you have the required permissions. Contact our Customer Champions for support if you do not have the necessary role or permissions.

In the Code42 app for Splunk

Install the Code42 app for Splunk to gain access to dashboards and other detailed information about file exfiltration activity in your Code42 environment.

For more information on Splunk, including their free trial that can be used with the Code42 app for Splunk, see Splunk's documentation.
