File operations

File Operations trigger in DLP policies

Trigger File operations in DLP policies allows monitoring of user actions on files and directories in selected locations. It enables precise specification of conditions that must be met for the system to execute the appropriate rule. This feature supports effective protection of organizational data against unauthorized access, modification, or deletion.

Types of file operations

The system enables monitoring and control of the following operations:

  • Creation: Detecting creation of new files.

  • Deletion: Monitoring attempts to delete files.

  • Open: Monitoring and logging of file open events also within a defined process.

  • Rename/move: Monitoring changes to file names or locations.

  • Write: Tracking changes saved within files.

Configuration fields

1

Operation type

You must define the operation type. This is a multi-select list.

  • Creation

  • Delete

  • Open

  • Rename/move

  • Save

2

Path mask / Excluded path mask

  • Path mask: Defines the locations in which operations will be monitored.

    • Examples: H:\desktop\test or H:\*.

  • Excluded path mask: Excludes specified locations from monitoring.

    • Example: for the mask H:\*, the exclusion may be H:\desktop\test.

File mask / Excluded file mask

  • File mask: Specifies the files to be included in monitoring.

    • Examples: invoice.pdf, invoice*.pdf, *.txt, *.jpg.

  • Excluded file mask: Excludes specific files from monitoring.

    • Example: for the mask *.jpg, the exclusion test.jpg will cause all JPG files except test.jpg to be considered.

Object type

The dropdown allows selection of the object type:

  • Directories: Monitoring only folder operations.

  • Files: Monitoring only file operations.

  • Files and directories: Monitoring both object types simultaneously.

5

Applies to media

The multi-select field allows specification of media on which operations are to be monitored:

  • Local drive

  • External drive

  • USB flash drive

  • Network share

Additional option for USB flash drives:

Selecting USB flash drives unlocks configuration of USB device groups:

  • USB device groups: A dropdown list initially containing the value “All”. Groups are created from the list of previously detected USB devices.

6

Process mask / Excluded process mask

Works analogously to file and path masks:

  • Process mask: Specifies processes to be included, e.g. chrome.exe, *.exe.

  • Excluded process mask: Excludes specified processes, e.g. for the mask *.exe, the exclusion chrome.exe.

A multi-select field available after tags have been created in the system.

  • Allows restricting the DLP rule to files that have a specific tag (e.g., classification).

  • Example: It is possible to set the mask * (all locations and files), making the only condition for the policy to apply the assignment of a tag to the file.

Practical application

Example:

The rule applies to:

  • Operations: Open.

  • Locations: User desktop.

  • File types: Text files (.txt).

  • Media: Local drive.

  • Process: Word.exe.

Result: The DLP policy will be applied to files .txt located on the local drive in the “Desktop” directory, opened exclusively with Word.

Summary

Trigger File operations allows detailed monitoring and management of access to files in selected locations, on specified media, and when using selected processes. Thanks to flexible configuration of fields, it is possible to precisely tailor DLP rules to the specific requirements of the organization.
