Cisco Cisco Email Security Appliance C160 Mode D'Emploi

Advanced Malware Protection uses cloud-based services to protect against zero-day and targeted 
file-based threats in email attachments by: 

Obtaining each file’s reputation. 

Analyzing behavior of certain files with unknown reputations. 

Notifying you about files that are determined to be threats after they have entered your network. 

These features are available only for  incoming messages. Files attached to outgoing messages are not 
evaluated. 

Threat verdicts can change as new information emerges. A file may initially be evaluated as unknown or 
clean, and the file may therefore be released to the recipient. If the threat verdict changes, you will be 
alerted, and the file and its new verdict appear in the AMP Verdict Updates report. You can investigate 
the point-of-entry message as a starting point to remediating any impacts of the threat. 

Verdicts can also change from malicious to clean. 

When the appliance processes subsequent instances of the same file, the updated verdict is immediately 
applied.
