File Security Actions
File Security Profile Actions
When creating File Rules within a File Security Profile (FSP), Actions must be applied to each File Matcher rule. File Matcher rules are processed in the order of rule priority as indicated by their numerical order in the File Rules column.
The following Actions can be applied to each File Matcher in an FSP:
| Action | Description |
|---|---|
| Allow | Allows the file to pass, logging the event and file information |
| Block | Blocks the file from passing, logging the event and file information |
| Fast Scan | This applies static analysis and hash-based malware scanning engines to files to look for matches to known malware. Fast Scan can be customized by adding specific file types and built-in scanning Dictionaries when the File Matcher is created/edited.This method of malware scanning has the least impact on the end user's experience. Files with malware detected are blocked and logged. |
| Deep Scan | This directs the matched file to the Atmos Sandbox engine, where the file is dynamically analyzed to detect deeply embedded malware that requires executing or opening the file to trigger an attack. The Atmos Sandbox engine enables dynamic analysis of files to detect deeply embedded malware that activates upon execution or opening. If malware is detected, the file is blocked and logged for further review. |
Reviewing Scan Results Using the Exploration Screen and Filters
Use the following steps to review Static and Dynamic scan results from the Exploration screen utilizing Filters.
