Configuring Centralized Reporting for Advanced Malware Protection Features 
If you will centralize reporting on a Security Management appliance, see important configuration 
requirements in the Advanced Malware Protection sections in the email reporting chapter of the online 
help or user guide for your management appliance. 
File Reputation and File Analysis Reporting and Tracking 
Identifying Files by SHA-256 Hash 
Because filenames can easily be changed, the appliance generates an identifier for each file using a 
Secure Hash Algorithm (SHA-256). If an appliance processes the same file with different names, all 
instances are recognized as the same SHA-256. If multiple appliances process the same file, all instances 
of the file have the same SHA-256 identifier. 
In most reports, files are listed by their SHA-256 value (in an abbreviated format).
