Explanation:
The file named isitbad.zip was not uploaded to Advanced Malware Protection (AMP) for analysis, and its
disposition is unknown. AMP is a feature of the Cisco Email Security Appliance (ESA) that can be used to test a
given file against a file reputation service in the cloud. The file reputation service that is used by AMP attempts
to authenticate a Secure Hash Algorithm 256 (SHA256) hash for the file that is being uploaded against the file
reputation database. The service also rates the data fidelity of the uploaded file by assigning it a reputation
score.
The AMP log output in this scenario indicates that the file named isitbad.zip has been determined to be 174,401
bytes and is a ZIP application file. The file was not uploaded to the cloud service, which is indicated by the
value of the Disposition field, which is unscannable. If the file had been uploaded, the upload_action field wouldcontain the same value, which is 1, and the Disposition field would contain a phrase that indicates that the file
was either unknown, or malicious. If the file that is being analyzed is already known to the file reputation
service, the upload_action field will contain a value of either 0 or 2 and will not be uploaded to the cloud.
