Email messages attachment filtering

The attachment filtering functionality is not applied to outgoing email messages.

Malicious applications can be distributed in the form of attachments in email messages. You can configure filtering based on the type of message attachments so that files of the specified types are automatically renamed or deleted. By renaming an attachment of a certain type, Kaspersky Endpoint Security can protect your computer against automatic execution of a malicious application.

To configure filtering of attachments:

1. In the main application window, click the button.
2. In the application settings window, select Essential Threat Protection → Mail Threat Protection.
3. Click Advanced Settings.
4. In the Attachment filter block, do one of the following:
   • Disable filtering. If this option is selected, the Mail Threat Protection component does not filter files that are attached to email messages.
   • Rename attachments of selected types. If this option is selected, the Mail Threat Protection component will replace the last extension character found in the attached files of the specified types with the underscore character (for example, attachment.doc_). Thus, in order to open the file, the user must rename the file.
   • Delete attachments of selected types. If this option is selected, the Mail Threat Protection component deletes attached files of the specified types from email messages.
5. If you selected the Rename attachments of selected types option or the Delete attachments of selected types option during the previous step, select the check boxes opposite the relevant types of files.
6. Save your changes.
