A post action represents an operation that happens automatically after the file is processed. For now, the available options are to add tags to a file (only for Amazon S3) and to sanitize files by making use of OPSWAT’s Deep CDR technology.

Enable file tagging for S3 storage

From the left-side navigation menu, go to Storage units
Select the storage for which you wish to enable file tagging
Click on Remediation actions in the actions dropdown
Toggle File tagging from the Remediation Actions window

The post/remediation action adds the following tag names and respective values:

Name	Value	Description
MetaDefenderResult	Allowed / Blocked	The final result of the processing
MetaDefenderFileId	5e7e15f132efdd0006b0e132	A unique file identifier that can be used for further REST API queries
MetaDefenderAnalysisTimestamp	2020-03-28T21:43:40.1500000Z	Date and time in UTC format when file processing has started

Deep CDR

Turning the File Sanitization feature on creates a safer version of the file by stripping it of potentially harmful content. This is done using OPSWAT’s Deep Content Disarm and Reconstruction technology.

To learn more about how to configure Deep CDR, please check the Deep CDR user guide.

Enable Deep CDR

From the left-side navigation menu, go to Storage units
Select the storage for which you wish to enable file tagging
Click on Remediation actions in the actions dropdown
Go to Deep CDR tab in the Remediation Actions menu
Toggle File sanitization
Choose how the original file should be treated after sanitization by selecting one of the three available options
1. Keep original file - the original file will be retained as is
2. Encrypt original file - the original file will be encrypted and retained as a backup. This is useful because later you could decrypt it and revert to the original file if needed
3. Delete original file - the original file will be deleted and only the sanitized version will be available to users (NOTE: You will not be able to revert to the original file anymore)
